Appendix A – Cisco Nexus 9372 Switch Configuration
To keep pace with the market, you need systems that support rapid, agile development processes. Cisco HyperFlex™ Systems let you unlock the full potential of hyper-convergence and adapt IT to the needs of your workloads. The systems use an end-to-end software-defined infrastructure approach, combining software-defined computing in the form of Cisco HyperFlex HX-Series Nodes, software-defined storage with the powerful Cisco HyperFlex HX Data Platform, and software-defined networking with the Cisco UCS fabric that integrates smoothly with Cisco® Application Centric Infrastructure (Cisco ACI™).
Together with a single point of connectivity and management, these technologies deliver a pre-integrated and adaptable cluster with a unified pool of resources that you can quickly deploy, adapt, scale, and manage to efficiently power your applications and your business
This document provides an architectural reference and design guide for up to a 4000 user mixed workload on a 32-node (16 Cisco HyperFlex HXAF220c-M4SX servers plus 8 Cisco UCS B200 M4 blade servers and 8 Cisco UCS C220 M4 rack servers) Cisco HyperFlex system. We provide deployment guidance and performance data for VMware Horizon 7 virtual desktops running Microsoft Windows 10 with Office 2016 Linked-Clone, Instant-Clone and Persistent virtual desktops as well as Windows Server 2016 RDS server-based sessions on vSphere 6. The solution is a pre-integrated, best-practice data center architecture built on the Cisco Unified Computing System (UCS), the Cisco Nexus® 9000 family of switches and Cisco HyperFlex Data Platform software version 2.1.1b.
The solution payload is 100 percent virtualized on Cisco HyperFlex HXAF220c-M4SX hyperconverged nodes, Cisco UCS C220 M4 rack servers and Cisco UCS B200 M4 blade servers booting via on-board Flex-Flash controller SD cards running VMware vSphere 6.0 U3 hypervisor. The virtual desktops are configured with VMware Horizon 7, which incorporates both traditional persistent and non-persistent virtual Windows 7/8/10 desktops, hosted applications and remote desktop service (RDS) server 2008 R2, server 2012 R2 or server 2016 based desktops. The solution provides unparalleled scale and management simplicity. VMware Horizon instant-clone floating assignment Windows 10 desktops (2000,) full clone desktops (1000) or RDSH server based desktops (1000) can be provisioned on a thirty two node Cisco HyperFlex cluster. Where applicable, this document provides best practice recommendations and sizing guidelines for customer deployment of this solution.
The solution boots 4000 virtual desktops and RDSH virtual server machines in 15 minutes or less, insuring that users will not experience delays in accessing their virtual workspace on HyperFlex.
The solution provides outstanding virtual desktop end user experience as measured by the Login VSI 4.1 Knowledge Worker workload running in benchmark mode. Average end-user response times for all tested delivery methods is under 1 second, representing the best performance in the industry.
Introduction
A current industry trend in data center design is towards small, granularly expandable hyperconverged infrastructures. By using virtualization along with pre-validated IT platforms, customers of all sizes have embarked on the journey to “just in time capacity” using this new technology. The Cisco Hyper Converged Solution can be quickly deployed, thereby increasing agility and reducing costs. Cisco HyperFlex uses best of breed storage, server and network components to serve as the foundation for desktop virtualization workloads, enabling efficient architectural designs that can be quickly and confidently deployed and scaled out.
Audience
The audience for this document includes, but is not limited to; sales engineers, field consultants, professional services, IT managers, partner engineers, and customers who want to take advantage of an infrastructure built to deliver IT efficiency and enable IT innovation.
Purpose of this Document
This document provides a step-by-step design, configuration, and implementation guide for the Cisco Validated Design for a Cisco HyperFlex All-Flash system running four different VMware Horizon 7 workloads with Cisco UCS 6248UP Fabric Interconnects and Cisco Nexus 9300 series switches.
What’s New?
This is the first Cisco Validated Design with Cisco HyperFlex All-Flash system running Virtual Desktop Infrastructure with compute only nodes included. It incorporates the following features:
· Validation of Cisco Nexus 9000 with Cisco HyperFlex
· Support for the Cisco UCS 3.1(2) release and Cisco HyperFlex v 2.1.1
· VMware vSphere 6.0 U3 Hypervisor
· VMware Horizon 7 Instant Clones, Linked Clones, Persistent Desktops and RDSH shared server sessions
The data center market segment is shifting toward heavily virtualized private, hybrid and public cloud computing models running on industry-standard systems. These environments require uniform design points that can be repeated for ease if management and scalability.
These factors have led to the need predesigned computing, networking and storage building blocks optimized to lower the initial design cost, simply management, and enable horizontal scalability and high levels of utilization.
The use cases include:
· Enterprise Data Center (small failure domains)
· Service Provider Data Center (small failure domains)
· Commercial Data Center
· Remote Office/Branch Office
· SMB Standalone Deployments
This Cisco Validated Design prescribes a defined set of hardware and software that serves as an integrated foundation for both Horizon Microsoft Windows 10 virtual desktops and Horizon RDSH server desktop sessions based on Microsoft Server 2016. The mixed workload solution includes Cisco HyperFlex hardware and Data Platform software, Cisco Nexus® switches, the Cisco Unified Computing System (Cisco UCS®), VMware Horizon and VMware vSphere software in a single package. The design is efficient such that the networking, computing, and storage components occupy 34-rack units footprint in an industry standard 42U rack. Port density on the Cisco Nexus switches and Cisco UCS Fabric Interconnects enables the networking components to accommodate multiple HyperFlex clusters in a single Cisco UCS domain.
A key benefit of the Cisco Validated Design architecture is the ability to customize the environment to suit a customer's requirements. A Cisco Validated Design scales easily as requirements and demand change. The unit can be scaled both up (adding resources to a Cisco Validated Design unit) and out (adding more Cisco Validated Design units).
The reference architecture detailed in this document highlights the resiliency, cost benefit, and ease of deployment of a hyper-converged desktop virtualization solution. A solution capable of consuming multiple protocols across a single interface allows for customer choice and investment protection because it truly is a wire-once architecture.
The combination of technologies from Cisco Systems, Inc. and VMware Inc. produced a highly efficient, robust and affordable desktop virtualization solution for a virtual desktop, hosted shared desktop or mixed deployment supporting different use cases. Key components of the solution include the following:
· More power, same size. Cisco HX-series nodes, Cisco UCS rack servers and Cisco UCS blade servers with dual 14-core 2.6 GHz Intel Xeon (E5-2690v4) processors and 512GB of memory for VMware Horizon support more virtual desktop workloads than the previously released generation processors on the same hardware. The Intel Xeon E5-2690 v4 14-core processors used in this study provided a balance between increased per-server capacity and cost.
· Fault-tolerance with high availability built into the design. The various designs are based on multiple Cisco HX-Series nodes, Cisco UCS rack servers and Cisco UCS blade servers for virtual desktop and infrastructure workloads. The design provides N+1 server fault tolerance for every payload type tested.
· Stress-tested to the limits during aggressive boot scenario. The 4000 user mixed hosted virtual desktop and hosted shared desktop environment booted and registered with the Horizon 7 in under 15 minutes, providing our customers with an extremely fast, reliable cold-start desktop virtualization system.
· Stress-tested to the limits during simulated login storms. All 4000 users logged in and started running workloads up to steady state in 48-minutes without overwhelming the processors, exhausting memory or exhausting the storage subsystems, providing customers with a desktop virtualization system that can easily handle the most demanding login and startup storms.
· Ultra-condensed computing for the datacenter. The rack space required to support the initial 4000 user system is 34 rack units, including Cisco Nexus Switching and Cisco Fabric interconnects. Incremental 4000 seat Cisco HyperFlex clusters can be added in 30 rack unit groups, conserving valuable data center floor space.
· 100 percent virtualized: This CVD presents a validated design that is 100 percent virtualized on VMware ESXi 6.0. All of the virtual desktops, user data, profiles, and supporting infrastructure components, including Active Directory, SQL Servers, VMware Horizon components, Horizon VDI desktops and RDSH servers were hosted as virtual machines. This provides customers with complete flexibility for maintenance and capacity additions because the entire system runs on the Cisco HyperFlex hyper-converged infrastructure with stateless Cisco UCS HX-series servers. (Infrastructure VMs were hosted on two Cisco UCS C220 M4 Rack Servers outside of the HX cluster to deliver the highest capacity and best economics for the solution.)
· Cisco data center management: Cisco maintains industry leadership with the new Cisco UCS Manager 3.1(2) software that simplifies scaling, guarantees consistency, and eases maintenance. Cisco’s ongoing development efforts with Cisco UCS Manager, Cisco UCS Central, and Cisco UCS Director insure that customer environments are consistent locally, across Cisco UCS Domains and across the globe. Cisco UCS software suite offers increasingly simplified operational and deployment management, and it continues to widen the span of control for customer organizations’ subject matter experts in compute, storage and network.
· Cisco 10G Fabric: Our 10G unified fabric story gets additional validation on 6200 Series Fabric Interconnects as Cisco runs more challenging workload testing, while maintaining unsurpassed user response times.
· Cisco HyperFlex storage performance: Cisco HyperFlex provides industry-leading hyper converged storage performance that efficiently handles the most demanding I/O bursts (for example, login storms), high write throughput at low latency, delivers simple and flexible business continuity and helps reduce storage cost per desktop.
· Cisco HyperFlex agility: Cisco HyperFlex System enables users to seamlessly add, upgrade or remove storage from the infrastructure to meet the needs of the virtual desktops.
· Cisco HyperFlex vCenter integration: Cisco HyperFlex plugin for VMware vSphere provides easy-button automation for key storage tasks such as storage provisioning and storage resize, cluster health status and performance monitoring directly from the VCenter web client in a single pane of glass. Experienced vCenter administrators have a near zero learning curve when HyperFlex is introduced into the environment.
· VMware Horizon 7 advantage: VMware Horizon 7 follows a new unified product architecture that supports both hosted-shared desktops and applications (RDS) and complete virtual desktops (VDI). This new Horizon release simplifies tasks associated with large-scale VDI management. This modular solution supports seamless delivery of Windows apps and desktops as the number of user increase. In addition, PCoIP and Blast extreme enhancements help to optimize performance and improve the user experience across a variety of endpoint device types, from workstations to mobile devices including laptops, tablets, and smartphones.
· Optimized for performance and scale. For hosted shared desktop sessions, the best performance was achieved when the number of vCPUs assigned to the Horizon 7 RDSH virtual machines did not exceed the number of hyper-threaded (logical) cores available on the server. In other words, maximum performance is obtained when not overcommitting the CPU resources for the virtual machines running virtualized RDS systems.
· Provisioning desktop machines made easy: VMware Horizon 7 provisions hosted virtual desktops as well as hosted shared desktop virtual machines for this solution using a single method for both, the “Automated floating assignment desktop pool.” “Dedicated user assigned desktop pool” for persistent desktops was provisioned in the same Horizon 7 administrative console. Horizon 7 introduces a new provisioning technique for non-persistent virtual desktops called “Instant-clone.” The new method greatly reduces the amount of life-cycle spend and the maintenance windows for the guest OS.
Cisco Desktop Virtualization Solutions: Data Center
The Evolving Workplace
Today’s IT departments are facing a rapidly evolving workplace environment. The workforce is becoming increasingly diverse and geographically dispersed, including offshore contractors, distributed call center operations, knowledge and task workers, partners, consultants, and executives connecting from locations around the world at all times.
This workforce is also increasingly mobile, conducting business in traditional offices, conference rooms across the enterprise campus, home offices, on the road, in hotels, and at the local coffee shop. This workforce wants to use a growing array of client computing and mobile devices that they can choose based on personal preference. These trends are increasing pressure on IT to ensure protection of corporate data and prevent data leakage or loss through any combination of user, endpoint device, and desktop access scenarios (Figure 1).
These challenges are compounded by desktop refresh cycles to accommodate aging PCs and bounded local storage and migration to new operating systems, specifically Microsoft Windows 10 and productivity tools, specifically Microsoft Office 2016.
Figure 1 Cisco Data Center Partner Collaboration
Some of the key drivers for desktop virtualization are increased data security, the ability to expand and contract capacity and reduced TCO through increased control and reduced management costs.
Cisco Desktop Virtualization Focus
Cisco focuses on three key elements to deliver the best desktop virtualization data center infrastructure: simplification, security, and scalability. The software combined with platform modularity provides a simplified, secure, and scalable desktop virtualization platform.
Simplified
Cisco UCS and Cisco HyperFlex provide a radical new approach to industry-standard computing and provides the core of the data center infrastructure for desktop virtualization. Among the many features and benefits of Cisco UCS are the drastic reduction in the number of servers needed and in the number of cables used per server, and the capability to rapidly deploy or re-provision servers through Cisco UCS service profiles. With fewer servers and cables to manage and with streamlined server and virtual desktop provisioning, operations are significantly simplified. Thousands of desktops can be provisioned in minutes with Cisco UCS Manager service profiles and Cisco storage partners’ storage-based cloning. This approach accelerates the time to productivity for end users, improves business agility, and allows IT resources to be allocated to other tasks.
Cisco UCS Manager automates many mundane, error-prone data center operations such as configuration and provisioning of server, network, and storage access infrastructure. In addition, Cisco UCS B-Series Blade Servers, C-Series and HX-Series Rack Servers with large memory footprints enable high desktop density that helps reduce server infrastructure requirements.
Simplification also leads to more successful desktop virtualization implementation. Cisco and its technology partners like VMware have developed integrated, validated architectures, including predefined hyper-converged architecture infrastructure packages such as HyperFlex. Cisco Desktop Virtualization Solutions have been tested with VMware vSphere.
Secure
Although virtual desktops are inherently more secure than their physical predecessors, they introduce new security challenges. Mission-critical web and application servers using a common infrastructure such as virtual desktops are now at a higher risk for security threats. Inter–virtual machine traffic now poses an important security consideration that IT managers need to address, especially in dynamic environments in which virtual machines, using VMware vMotion, move across the server infrastructure.
Desktop virtualization, therefore, significantly increases the need for virtual machine–level awareness of policy and security, especially given the dynamic and fluid nature of virtual machine mobility across an extended computing infrastructure. The ease with which new virtual desktops can proliferate magnifies the importance of a virtualization-aware network and security infrastructure. Cisco data center infrastructure (Cisco UCS and Cisco Nexus Family solutions) for desktop virtualization provides strong data center, network, and desktop security, with comprehensive security from the desktop to the hypervisor. Security is enhanced with segmentation of virtual desktops, virtual machine–aware policies and administration, and network security across the LAN and WAN infrastructure.
Scalable
Growth of a desktop virtualization solution is accelerating, so a solution must be able to scale, and scale predictably, with that growth. The Cisco Desktop Virtualization Solutions support high virtual-desktop density (desktops per server) and additional servers scale with near-linear performance. Cisco data center infrastructure provides a flexible platform for growth and improves business agility. Cisco UCS Manager service profiles allow on-demand desktop provisioning and make it just as easy to deploy dozens of desktops as it is to deploy thousands of desktops.
Cisco HyperFlex servers provide near-linear performance and scale. Cisco UCS implements the patented Cisco Extended Memory Technology to offer large memory footprints with fewer sockets (with scalability to up to 1 terabyte (TB) of memory with 2- and 4-socket servers). Using unified fabric technology as a building block, Cisco UCS server aggregate bandwidth can scale to up to 80 Gbps per server, and the northbound Cisco UCS fabric interconnect can output 2 terabits per second (Tbps) at line rate, helping prevent desktop virtualization I/O and memory bottlenecks. Cisco UCS, with its high-performance, low-latency unified fabric-based networking architecture, supports high volumes of virtual desktop traffic, including high-resolution video and communications traffic. In addition, Cisco HyperFlex helps maintain data availability and optimal performance during boot and login storms as part of the Cisco Desktop Virtualization Solutions. Recent Cisco Validated Designs based on VMware Horizon, Cisco HyperFlex solutions have demonstrated scalability and performance, with up to 4000 hosted virtual desktops and hosted shared desktops up and running in 15 minutes.
Cisco UCS and Cisco Nexus data center infrastructure provides an excellent platform for growth, with transparent scaling of server, network, and storage resources to support desktop virtualization, data center applications, and cloud computing.
Savings and Success
The simplified, secure, scalable Cisco data center infrastructure for desktop virtualization solutions saves time and money compared to alternative approaches. Cisco UCS enables faster payback and ongoing savings (better ROI and lower TCO) and provides the industry’s greatest virtual desktop density per server, reducing both capital expenditures (CapEx) and operating expenses (OpEx). The Cisco UCS architecture and Cisco Unified Fabric also enables much lower network infrastructure costs, with fewer cables per server and fewer ports required. In addition, storage tiering and deduplication technologies decrease storage costs, reducing desktop storage needs by up to 50 percent.
The simplified deployment of Cisco HyperFlex for desktop virtualization accelerates the time to productivity and enhances business agility. IT staff and end users are more productive more quickly, and the business can respond to new opportunities quickly by deploying virtual desktops whenever and wherever they are needed. The high-performance Cisco systems and network deliver a near-native end-user experience, allowing users to be productive anytime and anywhere.
The key measure of desktop virtualization for any organization is its efficiency and effectiveness in both the near term and the long term. The Cisco Desktop Virtualization Solutions are very efficient, allowing rapid deployment, requiring fewer devices and cables, and reducing costs. The solutions are also extremely effective, providing the services that end users need on their devices of choice while improving IT operations, control, and data security. Success is bolstered through Cisco’s best-in-class partnerships with leaders in virtualization and through tested and validated designs and services to help customers throughout the solution lifecycle. Long-term success is enabled through the use of Cisco’s scalable, flexible, and secure architecture as the platform for desktop virtualization.
The ultimate measure of desktop virtualization for any end user is a great experience. Cisco HyperFlex delivers class-leading performance with sub-second base line response times and index average response times at full load of just under one second.

Figure 2 shows the VMware Horizon 7 on vSphere 6 built on Cisco Validated Design components and the network connections. The reference architecture reinforces the "wire-once" strategy, because as additional storage is added to the architecture, no re-cabling is required from the hosts to the Cisco UCS fabric interconnect.
Physical Topology
The Cisco HyperFlex system is composed of a pair of Cisco UCS 6248UP Fabric Interconnects, along with up to 16 HXAF-Series rack mount servers per cluster. In addition, up to 16 compute only servers can be added per cluster. Adding Cisco UCS 5108 blade chassis allows use of Cisco UCS B200 M4 blade servers for additional compute resources in a hybrid cluster design. Cisco UCS C240 and C220 servers can also be used for additional compute resources. Up to 8 separate HX clusters can be installed under a single pair of Fabric Interconnects. The Fabric Interconnects both connect to every HX-Series rack mount server, and both connect to every Cisco UCS 5108 blade chassis. Upstream network connections, also referred to as “northbound” network connections are made from the Fabric Interconnects to the customer datacenter network at the time of installation.
For this study, we uplinked the Cisco 6248UP Fabric Interconnects to Cisco Nexus 9372PX switches.
Figure 3 and Figure 4 illustrate the hyperconverged and hybrid hyperconverged, plus compute only topologies.
Figure 3 Cisco HyperFlex Standard Topology
Figure 4 Cisco HyperFlex Hyperconverged Plus Compute Only Node Topology
Fabric Interconnects
Fabric Interconnects (FI) are deployed in pairs, wherein the two units operate as a management cluster, while forming two separate network fabrics, referred to as the A side and B side fabrics. Therefore, many design elements will refer to FI A or FI B, alternatively called fabric A or fabric B. Both Fabric Interconnects are active at all times, passing data on both network fabrics for a redundant and highly available configuration. Management services, including Cisco UCS Manager, are also provided by the two FIs but in a clustered manner, where one FI is the primary, and one is secondary, with a roaming clustered IP address. This primary/secondary relationship is only for the management cluster, and has no effect on data transmission.
Fabric Interconnects have the following ports, which must be connected for proper management of the Cisco UCS domain:
· Mgmt: A 10/100/1000 Mbps port for managing the Fabric Interconnect and the Cisco UCS domain via GUI and CLI tools. Also used by remote KVM, IPMI and SoL sessions to the managed servers within the domain. This is typically connected to the customer management network.
· L1: A cross connect port for forming the Cisco UCS management cluster. This is connected directly to the L1 port of the paired Fabric Interconnect using a standard CAT5 or CAT6 Ethernet cable with RJ45 plugs. It is not necessary to connect this to a switch or hub.
· L2: A cross connect port for forming the Cisco UCS management cluster. This is connected directly to the L2 port of the paired Fabric Interconnect using a standard CAT5 or CAT6 Ethernet cable with RJ45 plugs. It is not necessary to connect this to a switch or hub.
· Console: An RJ45 serial port for direct console access to the Fabric Interconnect. Typically used during the initial FI setup process with the included serial to RJ45 adapter cable. This can also be plugged into a terminal aggregator or remote console server device.
HX-Series Rack Mount Servers
The HX-Series converged servers are connected directly to the Cisco UCS Fabric Interconnects in Direct Connect mode. This option enables Cisco UCS Manager to manage the HX-Series rack-mount Servers using a single cable for both management traffic and data traffic. Both the HXAF220c-M4S and HXAF240c-M4SX servers are configured with the Cisco VIC 1227 network interface card (NIC) installed in a modular LAN on motherboard (MLOM) slot, which has dual 10 Gigabit Ethernet (GbE) ports. The standard and redundant connection practice is to connect port 1 of the VIC 1227 to a port on FI A, and port 2 of the VIC 1227 to a port on FI B (Figure 5). Failure to follow this cabling practice can lead to errors, discovery failures, and loss of redundant connectivity.
Figure 5 HX-Series Server Connectivity
Cisco UCS B-Series Blade Servers
Hybrid HyperFlex clusters also incorporate 1-8 Cisco UCS B200-M4 blade servers for additional compute capacity. Like all other Cisco UCS B-series blade servers, the Cisco UCS B200-M4 must be installed within a Cisco UCS 5108 blade chassis. The blade chassis comes populated with 1-4 power supplies, and 8 modular cooling fans. In the rear of the chassis are two bays for installation of Cisco Fabric Extenders. The Fabric Extenders (also commonly called IO Modules, or IOMs) connect the chassis to the Fabric Interconnects. Internally, the Fabric Extenders connect to the Cisco VIC 1340 card installed in each blade server across the chassis backplane. The standard connection practice is to connect 1-4 10 GbE links from the left side IOM, or IOM 1, to FI A, and to connect the same number of 10 GbE links from the right side IOM, or IOM 2, to FI B (Figure 6). All other cabling configurations are invalid, and can lead to errors, discovery failures, and loss of redundant connectivity.
Figure 6 Cisco UCS 5108 Chassis Connectivity
Logical Network Design
The Cisco HyperFlex system has communication pathways that fall into four defined zones (Figure 6):
· Management Zone: This zone comprises the connections needed to manage the physical hardware, the hypervisor hosts, and the storage platform controller virtual machines (SCVM). These interfaces and IP addresses need to be available to all staff who will administer the HX system, throughout the LAN/WAN. This zone must provide access to Domain Name System (DNS) and Network Time Protocol (NTP) services, and allow Secure Shell (SSH) communication. In this zone are multiple physical and virtual components:
- Fabric Interconnect management ports.
- Cisco UCS external management interfaces used by the servers and blades, which answer through the FI management ports.
- ESXi host management interfaces.
- Storage Controller VM management interfaces.
- A roaming HX cluster management interface.
· VM Zone: This zone comprises the connections needed to service network IO to the guest VMs that will run inside the HyperFlex hyperconverged system. This zone typically contains multiple VLANs, that are trunked to the Cisco UCS Fabric Interconnects via the network uplinks, and tagged with 802.1Q VLAN IDs. These interfaces and IP addresses need to be available to all staff and other computer endpoints which need to communicate with the guest VMs in the HX system, throughout the LAN/WAN.
· Storage Zone: This zone comprises the connections used by the Cisco HX Data Platform software, ESXi hosts, and the storage controller VMs to service the HX Distributed Data Filesystem. These interfaces and IP addresses need to be able to communicate with each other at all times for proper operation. During normal operation, this traffic all occurs within the Cisco UCS domain, however there are hardware failure scenarios where this traffic would need to traverse the network northbound of the Cisco UCS domain. For that reason, the VLAN used for HX storage traffic must be able to traverse the network uplinks from the Cisco UCS domain, reaching FI A from FI B, and vice-versa. This zone is primarily jumbo frame traffic therefore jumbo frames must be enabled on the Cisco UCS uplinks. In this zone are multiple components:
- A vmkernel interface used for storage traffic for each ESXi host in the HX cluster.
- Storage Controller VM storage interfaces.
- A roaming HX cluster storage interface.
· VMotion Zone: This zone comprises the connections used by the ESXi hosts to enable vMotion of the guest VMs from host to host. During normal operation, this traffic all occurs within the Cisco UCS domain, however there are hardware failure scenarios where this traffic would need to traverse the network northbound of the Cisco UCS domain. For that reason, the VLAN used for HX storage traffic must be able to traverse the network uplinks from the Cisco UCS domain, reaching FI A from FI B, and vice-versa.
Figure 7 illustrates the logical network design.
Figure 7 Logical Network Design
The reference hardware configuration includes:
· Two Cisco Nexus 9372PX switches
· Two Cisco UCS 6248UP fabric interconnects
· Sixteen Cisco HX-series Rack server running HyperFlex data platform version 2.1.1bEight Cisco UCS B200 M4 blade server and eight Cisco UCS C220 M4 rack server running HyperFlex data platform version 2.1.1b as compute-only nodes.
For desktop virtualization, the deployment includes VMware Horizon 7 running on VMware vSphere 6. The design is intended to provide a large scale building block for both RDSH and persistent/non-persistent desktops with following density per thirty-two node configuration:
· 1000 Horizon 7 RDSH server desktop sessions
· 2000 Horizon 7 Windows 10 non-persistent virtual desktops
· 1000 Horizon 7 Windows 10 persistent virtual desktops
All of the Windows 10 virtual desktops were provisioned with 2GB of memory for this study. Typically, persistent desktop users may desire more memory. If 3GB or more of memory is needed, the third memory channel on the Cisco HXAF220c-M4S HX-Series rack server, Cisco UCS C220 M4 rack server and Cisco UCS B200 M4 servers should be populated.
Data provided here will allow customers to run RDSH server sessions and VDI desktops to suit their environment. For example, additional Cisco HX server can be deployed in compute-only manner to increase compute capacity or additional drives can be added in existing server to improve I/O capability and throughput, and special hardware or software features can be added to introduce new features. This document guides you through the low-level steps for deploying the base architecture, as shown in Figure 12.

Cisco Unified Computing System
Cisco UCS Manager (UCSM) provides unified, embedded management of all software and hardware components of the Cisco Unified Computing System™ (Cisco UCS) and Cisco HyperFlex through an intuitive GUI, a command-line interface (CLI), and an XML API. The manager provides a unified management domain with centralized management capabilities and can control multiple chassis and thousands of virtual machines.
Cisco UCS is a next-generation data center platform that unites computing, networking, and storage access. The platform, optimized for virtual environments, is designed using open industry-standard technologies and aims to reduce total cost of ownership (TCO) and increase business agility. The system integrates a low-latency; lossless 10 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. It is an integrated, scalable, multi-chassis platform in which all resources participate in a unified management domain.
Cisco Unified Computing System Components
The main components of Cisco UCS are:
· Compute: The system is based on an entirely new class of computing system that incorporates blade, rack and hyperconverged servers based on Intel® Xeon® processor E5-2600/4600 v4 and E7-2800 v4 family CPUs.
· Network: The system is integrated on a low-latency, lossless, 10-Gbps unified network fabric. This network foundation consolidates LANs, SANs, and high-performance computing (HPC) networks, which are separate networks today. The unified fabric lowers costs by reducing the number of network adapters, switches, and cables needed, and by decreasing the power and cooling requirements.
· Virtualization: The system unleashes the full potential of virtualization by enhancing the scalability, performance, and operational control of virtual environments. Cisco security, policy enforcement, and diagnostic features are now extended into virtualized environments to better support changing business and IT requirements.
· Storage: The Cisco HyperFlex rack servers provide high performance, resilient storage using the powerful HX Data Platform software. Customers can deploy as few as three nodes (replication factor 2/3,) depending on their fault tolerance requirements. These nodes form a HyperFlex storage and compute cluster. The onboard storage of each node is aggregated at the cluster level and automatically shared with all of the nodes. Storage resources are managed from the familiar VMware vCenter web client, extending the capability of vCenter administrators.
· Management: Cisco UCS uniquely integrates all system components, enabling the entire solution to be managed as a single entity by Cisco UCS Manager. The manager has an intuitive GUI, a CLI, and a robust API for managing all system configuration processes and operations.
Figure 8 Cisco HyperFlex Family Overview
Cisco UCS and Cisco HyperFlex are designed to deliver:
· Reduced TCO and increased business agility.
· Increased IT staff productivity through just-in-time provisioning and mobility support.
· A cohesive, integrated system that unifies the technology in the data center; the system is managed, serviced, and tested as a whole.
· Scalability through a design for hundreds of discrete servers and thousands of virtual machines and the capability to scale I/O bandwidth to match demand.
· Industry standards supported by a partner ecosystem of industry leaders.
Cisco UCS Manager provides unified, embedded management of all software and hardware components of the Cisco Unified Computing System across multiple chassis, rack servers, and thousands of virtual machines. Cisco UCS Manager manages Cisco UCS as a single entity through an intuitive GUI, a command-line interface (CLI), or an XML API for comprehensive access to all Cisco UCS Manager Functions.
The Cisco HyperFlex system provides a fully contained virtual server platform, with compute and memory resources, integrated networking connectivity, a distributed high performance log-structured file system for VM storage, and the hypervisor software for running the virtualized servers, all within a single Cisco UCS management domain.

· Support for Cisco HyperFlex Sizer — A new end to end sizing tool for compute, capacity and performance.
Cisco UCS Fabric Interconnect
The Cisco UCS 6200 Series Fabric Interconnects are a core part of Cisco UCS, providing both network connectivity and management capabilities for the system. The Cisco UCS 6200 Series offers line-rate, low-latency, lossless 10 Gigabit Ethernet, FCoE, and Fibre Channel functions.
The fabric interconnects provide the management and communication backbone for the Cisco UCS B-Series Blade Servers, Cisco UCS C-Series and HX-Series rack servers and Cisco UCS 5100 Series Blade Server Chassis. All servers, attached to the fabric interconnects become part of a single, highly available management domain. In addition, by supporting unified fabric, the Cisco UCS 6200 Series provides both LAN and SAN connectivity for all blades in the domain.
For networking, the Cisco UCS 6200 Series uses a cut-through architecture, supporting deterministic, low-latency, line-rate 10 Gigabit Ethernet on all ports, 1-terabit (Tb) switching capacity, and 160 Gbps of bandwidth per chassis, independent of packet size and enabled services. The product series supports Cisco low-latency, lossless, 10 Gigabit Ethernet unified network fabric capabilities, increasing the reliability, efficiency, and scalability of Ethernet networks. The fabric interconnects support multiple traffic classes over a lossless Ethernet fabric, from the blade server through the interconnect. Significant TCO savings come from an FCoE-optimized server design in which network interface cards (NICs), host bus adapters (HBAs), cables, and switches can be consolidated.

Cisco VIC 1227 MLOM Interface Card
The Cisco UCS Virtual Interface Card (VIC) 1227 is a dual-port Enhanced Small Form-Factor Pluggable (SFP+) 10-Gbps Ethernet and Fibre Channel over Ethernet (FCoE)-capable PCI Express (PCIe) modular LAN-on-motherboard (mLOM) adapter installed in the Cisco UCS HX-Series Rack Servers (Figure 6). The mLOM slot can be used to install a Cisco VIC without consuming a PCIe slot, which provides greater I/O expandability. It incorporates next-generation converged network adapter (CNA) technology from Cisco, providing investment protection for future feature releases. The card enables a policy-based, stateless, agile server infrastructure that can present up to 256 PCIe standards-compliant interfaces to the host that can be dynamically configured as either network interface cards (NICs) or host bus adapters (HBAs). The personality of the card is determined dynamically at boot time using the service profile associated with the server. The number, type (NIC or HBA), identity (MAC address and World Wide Name [WWN]), failover policy, bandwidth, and quality-of-service (QoS) policies of the PCIe interfaces are all determined using the service profile.

Cisco HyperFlex Converged Data Platform Software
The Cisco HyperFlex HX Data Platform is a purpose-built, high-performance, distributed file system with a wide array of enterprise-class data management services. The data platform’s innovations redefine distributed storage technology, exceeding the boundaries of first-generation hyperconverged infrastructures. The data platform has all the features that you would expect of an enterprise shared storage system, eliminating the need to configure and maintain complex Fibre Channel storage networks and devices. The platform simplifies operations and helps ensure data availability. Enterprise-class storage features include the following:
· Replication replicates data across the cluster so that data availability is not affected if single or multiple components fail (depending on the replication factor configured).
· Deduplication is always on, helping reduce storage requirements in virtualization clusters in which multiple operating system instances in client virtual machines result in large amounts of replicated data.
· Compression further reduces storage requirements, reducing costs, and the log- structured file system is designed to store variable-sized blocks, reducing internal fragmentation.
· Thin provisioning allows large volumes to be created without requiring storage to support them until the need arises, simplifying data volume growth and making storage a “pay as you grow” proposition.
· Fast, space-efficient clones rapidly replicate storage volumes so that virtual machines can be replicated simply through metadata operations, with actual data copied only for write operations.
· Snapshots help facilitate backup and remote-replication operations: needed in enterprises that require always-on data availability.
Cisco HyperFlex HX Data Platform Administration Plug-in
The Cisco HyperFlex HX Data Platform is administered through a VMware vSphere web client plug-in. Through this centralized point of control for the cluster, administrators can create volumes, monitor the data platform health, and manage resource use. Administrators can also use this data to predict when the cluster will need to be scaled. For customers that prefer a light weight web interface there is a tech preview URL management interface available by opening a browser to the IP address of the HX cluster interface. Additionally, there is an interface to assist in running cli commands through a web browser.

To run CLI commands via HTTP, connect to HX controller cluster IP (Figure 27).
Cisco HyperFlex HX Data Platform Controller
A Cisco HyperFlex HX Data Platform controller resides on each node and implements the distributed file system. The controller runs in user space within a virtual machine and intercepts and handles all I/O from guest virtual machines. The platform controller VM uses the VMDirectPath I/O feature to provide PCI pass-through control of the physical server’s SAS disk controller. This method gives the controller VM full control of the physical disk resources, utilizing the SSD drives as a read/write caching layer, and the HDDs as a capacity layer for distributed storage. The controller integrates the data platform into VMware software through the use of two preinstalled VMware ESXi vSphere Installation Bundles (VIBs):
· IO Visor: This VIB provides a network file system (NFS) mount point so that the ESXi hypervisor can access the virtual disks that are attached to individual virtual machines. From the hypervisor’s perspective, it is simply attached to a network file system.
· VMware API for Array Integration (VAAI): This storage offload API allows vSphere to request advanced file system operations such as snapshots and cloning. The controller implements these operations through manipulation of metadata rather than actual data copying, providing rapid response, and thus rapid deployment of new environments.
Replication Factor
The policy for the number of duplicate copies of each storage block is chosen during cluster setup, and is referred to as the replication factor (RF).
· Replication Factor 3: For every I/O write committed to the storage layer, 2 additional copies of the blocks written will be created and stored in separate locations, for a total of 3 copies of the blocks. Blocks are distributed in such a way as to ensure multiple copies of the blocks are not stored on the same disks, nor on the same nodes of the cluster. This setting can tolerate simultaneous failures 2 entire nodes without losing data and resorting to restore from backup or other recovery processes.
· Replication Factor 2: For every I/O write committed to the storage layer, 1 additional copy of the blocks written will be created and stored in separate locations, for a total of 2 copies of the blocks. Blocks are distributed in such a way as to ensure multiple copies of the blocks are not stored on the same disks, nor on the same nodes of the cluster. This setting can tolerate a failure 1 entire node without losing data and resorting to restore from backup or other recovery processes.
Data Distribution
Incoming data is distributed across all nodes in the cluster to optimize performance using the caching tier (Figure 28). Effective data distribution is achieved by mapping incoming data to stripe units that are stored evenly across all nodes, with the number of data replicas determined by the policies you set. When an application writes data, the data is sent to the appropriate node based on the stripe unit, which includes the relevant block of information. This data distribution approach in combination with the capability to have multiple streams writing at the same time avoids both network and storage hot spots, delivers the same I/O performance regardless of virtual machine location, and gives you more flexibility in workload placement. This contrasts with other architectures that use a data locality approach that does not fully use available networking and I/O resources and is vulnerable to hot spots.
Figure 28 Data is Striped Across Nodes in the Cluster
When moving a virtual machine to a new location using tools such as VMware Dynamic Resource Scheduling (DRS), the Cisco HyperFlex HX Data Platform does not require data to be moved. This approach significantly reduces the impact and cost of moving virtual machines among systems.
Data Operations
The data platform implements a distributed, log-structured file system that changes how it handles caching and storage capacity depending on the node configuration.
In the all-flash-memory configuration, the data platform uses a caching layer in SSDs to accelerate write responses, and it implements the capacity layer in SSDs. Read requests are fulfilled directly from data obtained from the SSDs in the capacity layer. A dedicated read cache is not required to accelerate read operations.
Incoming data is striped across the number of nodes required to satisfy availability requirements—usually two or three nodes. Based on policies you set, incoming write operations are acknowledged as persistent after they are replicated to the SSD drives in other nodes in the cluster. This approach reduces the likelihood of data loss due to SSD or node failures. The write operations are then de-staged to SSDs in the capacity layer in the all-flash memory configuration for long-term storage.
The log-structured file system writes sequentially to one of two write logs (three in case of RF=3) until it is full. It then switches to the other write log while de-staging data from the first to the capacity tier. When existing data is (logically) overwritten, the log-structured approach simply appends a new block and updates the metadata. This layout benefits SSD configurations in which seek operations are not time consuming. It reduces the write amplification levels of SSDs and the total number of writes the flash media experiences due to incoming writes and random overwrite operations of the data.
When data is de-staged to the capacity tier in each node, the data is deduplicated and compressed. This process occurs after the write operation is acknowledged, so no performance penalty is incurred for these operations. A small deduplication block size helps increase the deduplication rate. Compression further reduces the data footprint. Data is then moved to the capacity tier as write cache segments are released for reuse (Figure 29).
Figure 29 Data Write Operation Flow Through the Cisco HyperFlex HX Data Platform
Hot data sets—data that are frequently or recently read from the capacity tier—are cached in memory. All-Flash configurations, however, does not use an SSD read cache since there is no performance benefit of such a cache; the persistent data copy already resides on high-performance SSDs. In these configurations, a read cache implemented with SSDs could become a bottleneck and prevent the system from using the aggregate bandwidth of the entire set of SSDs.
Data Optimization
The Cisco HyperFlex HX Data Platform provides finely detailed data deduplication and variable block inline compression that is always on for objects in the cache (SSD and memory) and capacity (SSD or HDD) layers. Unlike other solutions, which require you to turn off these features to maintain performance, the deduplication and compression capabilities in the Cisco data platform are designed to sustain and enhance performance and significantly reduce physical storage capacity requirements.
Data Deduplication
Data deduplication is used on all storage in the cluster, including memory and SSD drives. Based on a patent-pending Top-K Majority algorithm, the platform uses conclusions from empirical research that show that most data, when sliced into small data blocks, has significant deduplication potential based on a minority of the data blocks. By fingerprinting and indexing just these frequently used blocks, high rates of deduplication can be achieved with only a small amount of memory, which is a high-value resource in cluster nodes (Figure 30).
Figure 30 Cisco HyperFlex HX Data Platform Optimizes Data Storage with No Performance Impact
Inline Compression
The Cisco HyperFlex HX Data Platform uses high-performance inline compression on data sets to save storage capacity. Although other products offer compression capabilities, many negatively affect performance. In contrast, the Cisco data platform uses CPU-offload instructions to reduce the performance impact of compression operations. In addition, the log-structured distributed-objects layer has no effect on modifications (write operations) to previously compressed data. Instead, incoming modifications are compressed and written to a new location, and the existing (old) data is marked for deletion, unless the data needs to be retained in a snapshot.
The data that is being modified does not need to be read prior to the write operation. This feature avoids typical read-modify-write penalties and significantly improves write performance.
Log-Structured Distributed Objects
In the Cisco HyperFlex HX Data Platform, the log-structured distributed-object store layer groups and compresses data that filters through the deduplication engine into self-addressable objects. These objects are written to disk in a log-structured, sequential manner. All incoming I/O—including random I/O—is written sequentially to both the caching (SSD and memory) and persistent (SSD or HDD) tiers. The objects are distributed across all nodes in the cluster to make uniform use of storage capacity.
By using a sequential layout, the platform helps increase flash-memory endurance. Because read-modify-write operations are not used, there is little or no performance impact of compression, snapshot operations, and cloning on overall performance.
Data blocks are compressed into objects and sequentially laid out in fixed-size segments, which in turn are sequentially laid out in a log-structured manner (Figure 31). Each compressed object in the log-structured segment is uniquely addressable using a key, with each key fingerprinted and stored with a checksum to provide high levels of data integrity. In addition, the chronological writing of objects helps the platform quickly recover from media or node failures by rewriting only the data that came into the system after it was truncated due to a failure.
Figure 31 Cisco HyperFlex HX Data Platform Optimizes Data Storage with No Performance Impact
Encryption
Securely encrypted storage optionally encrypts both the caching and persistent layers of the data platform. Integrated with enterprise key management software, or with passphrase-protected keys, encrypting data at rest helps you comply with HIPAA, PCI-DSS, FISMA, and SOX regulations. The platform itself is hardened to Federal Information Processing Standard (FIPS) 140-1 and the encrypted drives with key management comply with the FIPS 140-2 standard.
Data Services
The Cisco HyperFlex HX Data Platform provides a scalable implementation of space-efficient data services, including thin provisioning, space reclamation, pointer-based snapshots, and clones—without affecting performance.
Thin Provisioning
The platform makes efficient use of storage by eliminating the need to forecast, purchase, and install disk capacity that may remain unused for a long time. Virtual data containers can present any amount of logical space to applications, whereas the amount of physical storage space that is needed is determined by the data that is written. You can expand storage on existing nodes and expand your cluster by adding more storage-intensive nodes as your business requirements dictate, eliminating the need to purchase large amounts of storage before you need it.
Snapshots
The Cisco HyperFlex HX Data Platform uses metadata-based, zero-copy snapshots to facilitate backup operations and remote replication: critical capabilities in enterprises that require always-on data availability. Space-efficient snapshots allow you to perform frequent online data backups without worrying about the consumption of physical storage capacity. Data can be moved offline or restored from these snapshots instantaneously.
· Fast snapshot updates: When modified-data is contained in a snapshot, it is written to a new location, and the metadata is updated, without the need for read-modify-write operations.
· Rapid snapshot deletions: You can quickly delete snapshots. The platform simply deletes a small amount of metadata that is located on an SSD, rather than performing a long consolidation process as needed by solutions that use a delta-disk technique.
· Highly specific snapshots: With the Cisco HyperFlex HX Data Platform, you can take snapshots on an individual file basis. In virtual environments, these files map to drives in a virtual machine. This flexible specificity allows you to apply different snapshot policies on different virtual machines.
Many basic backup applications, read the entire dataset, or the changed blocks since the last backup at a rate that is usually as fast as the storage, or the operating system can handle. This can cause performance implications since HyperFlex is built on Cisco UCS with 10GbE which could result in multiple gigabytes per second of backup throughput. These basic backup applications, such as Windows Server Backup, should be scheduled during off-peak hours, particularly the initial backup if the application lacks some form of change block tracking.
Full featured backup applications, such as Veeam Backup and Replication v9.5, have the ability to limit the amount of throughput the backup application can consume which can protect latency sensitive applications during the production hours. With the release of v9.5 update 2, Veeam is the first partner to integrate HX native snapshots into the product. HX Native snapshots do not suffer the performance penalty of delta-disk snapshots, and do not require heavy disk IO impacting consolidation during snapshot deletion.
Particularly important for SQL administrators is the Veeam Explorer for SQL which can provide transaction level recovery within the Microsoft VSS framework. The three ways Veeam Explorer for SQL Server works to restore SQL Server databases include; from the backup restore point, from a log replay to a point in time, and from a log replay to a specific transaction – all without taking the VM or SQL Server offline.
Fast, Space-Efficient Clones
In the Cisco HyperFlex HX Data Platform, clones are writable snapshots that can be used to rapidly provision items such as virtual desktops and applications for test and development environments. These fast, space-efficient clones rapidly replicate storage volumes so that virtual machines can be replicated through just metadata operations, with actual data copying performed only for write operations. With this approach, hundreds of clones can be created and deleted in minutes. Compared to full-copy methods, this approach can save a significant amount of time, increase IT agility, and improve IT productivity.
Clones are deduplicated when they are created. When clones start diverging from one another, data that is common between them is shared, with only unique data occupying new storage space. The deduplication engine eliminates data duplicates in the diverged clones to further reduce the clone’s storage footprint.
Data Replication and Availability
In the Cisco HyperFlex HX Data Platform, the log-structured distributed-object layer replicates incoming data, improving data availability. Based on policies that you set, data that is written to the write cache is synchronously replicated to one or two other SSD drives located in different nodes before the write operation is acknowledged to the application. This approach allows incoming writes to be acknowledged quickly while protecting data from SSD or node failures. If an SSD or node fails, the replica is quickly re-created on other SSD drives or nodes using the available copies of the data.
The log-structured distributed-object layer also replicates data that is moved from the write cache to the capacity layer. This replicated data is likewise protected from SSD or node failures. With two replicas, or a total of three data copies, the cluster can survive uncorrelated failures of two SSD drives or two nodes without the risk of data loss. Uncorrelated failures are failures that occur on different physical nodes. Failures that occur on the same node affect the same copy of data and are treated as a single failure. For example, if one disk in a node fails and subsequently another disk on the same node fails, these correlated failures count as one failure in the system. In this case, the cluster could withstand another uncorrelated failure on a different node. See the Cisco HyperFlex HX Data Platform system administrator’s guide for a complete list of fault-tolerant configurations and settings.
If a problem occurs in the Cisco HyperFlex HX controller software, data requests from the applications residing in that node are automatically routed to other controllers in the cluster. This same capability can be used to upgrade or perform maintenance on the controller software on a rolling basis without affecting the availability of the cluster or data. This self-healing capability is one of the reasons that the Cisco HyperFlex HX Data Platform is well suited for production applications.
In addition, native replication transfers consistent cluster data to local or remote clusters. With native replication, you can snapshot and store point-in-time copies of your environment in local or remote environments for backup and disaster recovery purposes.
Data Rebalancing
A distributed file system requires a robust data rebalancing capability. In the Cisco HyperFlex HX Data Platform, no overhead is associated with metadata access, and rebalancing is extremely efficient. Rebalancing is a non-disruptive online process that occurs in both the caching and persistent layers, and data is moved at a fine level of specificity to improve the use of storage capacity. The platform automatically rebalances existing data when nodes and drives are added or removed or when they fail. When a new node is added to the cluster, its capacity and performance is made available to new and existing data. The rebalancing engine distributes existing data to the new node and helps ensure that all nodes in the cluster are used uniformly from capacity and performance perspectives. If a node fails or is removed from the cluster, the rebalancing engine rebuilds and distributes copies of the data from the failed or removed node to available nodes in the clusters.
Online Upgrades
Cisco HyperFlex HX-Series systems and the HX Data Platform support online upgrades so that you can expand and update your environment without business disruption. You can easily expand your physical resources; add processing capacity; and download and install BIOS, driver, hypervisor, firmware, and Cisco UCS Manager updates, enhancements, and bug fixes.

VMware vSphere 6.0
VMware provides virtualization software. VMware’s enterprise software hypervisors for servers—VMware vSphere ESX, vSphere ESXi, and VSphere—are bare-metal hypervisors that run directly on server hardware without requiring an additional underlying operating system. VMware vCenter Server for vSphere provides central management and complete control and visibility into clusters, hosts, virtual machines, storage, networking, and other critical elements of your virtual infrastructure.
VMware vSphere 6.0 introduces many enhancements to vSphere Hypervisor, VMware virtual machines, vCenter Server, virtual storage, and virtual networking, further extending the core capabilities of the vSphere platform.
VMware ESXi 6.0 Hypervisor
vSphere 6.0 introduces a number of new features in the hypervisor:
· Scalability Improvements
ESXi 6.0 dramatically increases the scalability of the platform. With vSphere Hypervisor 6.0, clusters can scale to as many as 64 hosts, up from 32 in previous releases. With 64 hosts in a cluster, vSphere 6.0 can support 8000 virtual machines in a single cluster. This capability enables greater consolidation ratios, more efficient use of VMware vSphere Distributed Resource Scheduler (DRS), and fewer clusters that must be separately managed. Each vSphere Hypervisor 6.0 instance can support up to 480 logical CPUs, 12 terabytes (TB) of RAM, and 1024 virtual machines. By using the newest hardware advances, ESXi 6.0 enables the virtualization of applications that previously had been thought to be non-virtualizable.
· Security Enhancements
- ESXi 6.0 offers these security enhancements:
o Account management: ESXi 6.0 enables management of local accounts on the ESXi server using new ESXi CLI commands. The capability to add, list, remove, and modify accounts across all hosts in a cluster can be centrally managed using a vCenter Server system. Previously, the account and permission management functions for ESXi hosts were available only for direct host connections. The setup, removal, and listing of local permissions on ESXi servers can also be centrally managed.
o Account lockout: ESXi Host Advanced System Settings have two new options for the management of failed local account login attempts and account lockout duration. These parameters affect Secure Shell (SSH) and vSphere Web Services connections, but not ESXi direct console user interface (DCUI) or console shell access.
o Password complexity rules: In previous versions of ESXi, password complexity changes had to be made by manually editing the /etc/pam.d/passwd file on each ESXi host. In vSphere 6.0, an entry in Host Advanced System Settings enables changes to be centrally managed for all hosts in a cluster.
o Improved auditability of ESXi administrator actions: Prior to vSphere 6.0, actions at the vCenter Server level by a named user appeared in ESXi logs with the vpxuser username: for example, [user=vpxuser]. In vSphere 6.0, all actions at the vCenter Server level for an ESXi server appear in the ESXi logs with the vCenter Server username: for example, [user=vpxuser: DOMAIN\User]. This approach provides a better audit trail for actions run on a vCenter Server instance that conducted corresponding tasks on the ESXi hosts.
o Flexible lockdown modes: Prior to vSphere 6.0, only one lockdown mode was available. Feedback from customers indicated that this lockdown mode was inflexible in some use cases. With vSphere 6.0, two lockdown modes are available:
· In normal lockdown mode, DCUI access is not stopped, and users on the DCUI access list can access the DCUI.
· In strict lockdown mode, the DCUI is stopped.
- Exception users: vSphere 6.0 offers a new function called exception users. Exception users are local accounts or Microsoft Active Directory accounts with permissions defined locally on the host to which these users have host access. These exception users are not recommended for general user accounts, but they are recommended for use by third-party applications—for service accounts, for example—that need host access when either normal or strict lockdown mode is enabled. Permissions on these accounts should be set to the bare minimum required for the application to perform its task and with an account that needs only read-only permissions on the ESXi host.
- Smart card authentication to DCUI: This function is for U.S. federal customers only. It enables DCUI login access using a Common Access Card (CAC) and Personal Identity Verification (PIV). The ESXi host must be part of an Active Directory domain.
VMware Horizon
VMware Horizon desktop virtualization solutions built on a unified architecture so they are simple to manage and flexible enough to meet the needs of all your organization's users. You use the same architecture and management tools to manage public, private, and hybrid cloud deployments as you do for on premises deployments
· VMware Horizon Virtual machines and RDSH known as server-based hosted sessions: These are applications hosted from Microsoft Windows servers to any type of device, including Windows PCs, Macs, smartphones, and tablets. Some VMware editions include technologies that further optimize the experience of using Windows applications on a mobile device by automatically translating native mobile-device display, navigation, and controls to Windows applications; enhancing performance over mobile networks; and enabling developers to optimize any custom Windows application for any mobile environment.
· VMware Horizon RDSH session users also known as server-hosted desktops: These are inexpensive, locked-down Windows virtual desktops hosted from Windows server operating systems. They are well suited for users, such as call center employees, who perform a standard set of tasks.
Advantages of Using VMware Horizon
VMware Horizon 7 version 7.1.0 provides the following new features and enhancements:
· Instant Clones
- A new type of desktop virtual machines that can be provisioned significantly faster than the traditional View Composer linked clones.
- A fully functional desktop can be provisioned in two seconds or less.
- Recreating a desktop pool with a new OS image can be accomplished in a fraction of the time it takes a View Composer desktop pool because the parent image can be prepared well ahead of the scheduled time of pool recreation.
- Clones are automatically rebalanced across available datastores.
- View storage accelerator is automatically enabled.
- You can use NVIDIA GRID vGPUs with instant-clone desktop pools. Configuring PCoIP as the display protocol with NVIDIA GRID vGPU is a technical preview feature.
- You can select multiple vLAN networks to create a larger instant-clone desktop pool. Only the static port group is supported.
- You can use the internal VM debug mode to troubleshoot internal virtual machines in an instant-clone desktop pool or in an instant-clone farm.
- Administrators can perform a restart or reset of the virtual desktops managed by the vCenter Server.
- You can perform maintenance on instant-clone virtual machines by putting the ESXi hosts into maintenance mode. Use vSphere Web Client to put the ESXi host into maintenance mode. The ESXi host maintenance operation automatically deletes the parent virtual machines from that ESXi host.
· VMware Blast Extreme
- VMware Blast Extreme is now fully supported on the Horizon platform.
- Connections to physical machines that have no monitors attached are supported with NVIDIA graphics cards. This is a technical preview feature for Horizon 7 version 7.1.
- The Blast Secure Gateway includes Blast Extreme Adaptive Transport (BEAT) networking, which dynamically adjusts to network conditions such as varying speeds and packet loss.
- Administrators can select the VMware Blast display protocol as the default or available protocol for pools, farms, and entitlements.
- End users can select the VMware Blast display protocol when connecting to remote desktops and applications.
- VMware Blast Extreme features include:
o TCP and UDP transport support
o H.264 support for the best performance across more devices
o Reduced device power consumption for longer battery life
o NVIDIA GRID acceleration for more graphical workloads per server, better performance, and a superior remote user experience
· True SSO
- For VMware Identity Manager integration, True SSO streamlines the end-to-end login experience. After users log in to VMware Identity Manager using a smart card or an RSA SecurID or RADIUS token, users are not required to also enter Active Directory credentials in order to use a remote desktop or application.
- Uses a short-lived Horizon virtual certificate to enable a password-free Windows login.
- Supports using either a native Horizon Client or HTML Access.
- System health status for True SSO appears in the Horizon Administrator dashboard.
- Can be used in a single domain, in a single forest with multiple domains, and in a multiple-forest, multiple-domain setup.
· Smart Policies
- Control of the clipboard cut-and-paste, client drive redirection, USB redirection, and virtual printing desktop features through defined policies.
- PCoIP session control through PCoIP profiles.
- Conditional policies based on user location, desktop tagging, pool name, and Horizon Client registry values.
· Configure the Clipboard Memory Size for VMware Blast and PCoIP Sessions
Horizon administrators can configure the server clipboard memory size by setting GPOs for VMware Blast and PCoIP sessions. Horizon Client 4.1 users on Windows, Linux, and Mac OS X systems can configure the client clipboard memory size. The effective memory size is the lesser of the server and client clipboard memory size values.
· VMware Blast Network Recovery Enhancements
Network recovery is now supported for VMware Blast sessions initiated from iOS, Android, Mac OS X, Linux, and Chrome OS clients. Previously, network recovery was supported only for Windows client sessions. If you lose your network connection unexpectedly during a VMware Blast session, Horizon Client attempts to reconnect to the network and you can continue to use your remote desktop or application. The network recovery feature also supports IP roaming, which means you can resume your VMware Blast session after switching to a WiFi network.
· Configure Horizon Administrator to not remember the login name
Horizon administrators can configure not to display the Remember user name check box and therefore not remember the administrator's login name.
· Allow Mac OS X Users to Save Credentials
Horizon administrators can configure Connection Server to allow Horizon Client Mac OS X systems to remember a user's user name, password, and domain information. If users choose to have their credentials saved, the credentials are added to the login fields in Horizon Client on subsequent connections.
· Windows 10
- Windows 10 is supported as a desktop guest operating system
- Horizon Client runs on Windows 10
- Smart card is supported on Windows 10.
- The Horizon User Profile Migration tool migrates Windows 7, 8/8.1, Server 2008 R2, or Server 2012 R2 user profiles to Windows 10 user profiles.
· RDS Desktops and Hosted Apps
- View Composer. View Composer and linked clones provide automated and efficient management of RDS server farms.
- Graphics Support. Existing 3D vDGA and GRID vGPU graphics solutions on VDI desktops have been extended to RDS hosts, enabling graphics-intensive applications to run on RDS desktops and Hosted Apps.
- Enhanced Load Balancing. A new capability provides load balancing of server farm applications based on memory and CPU resources.
- One-Way AD Trusts

What are VMware RDS Hosted Sessions?
The following describes the VMware RDS Hosted Sessions:
· An RDS host is a server computer that hosts applications and desktop sessions for remote access. An RDS host can be a virtual machine or a physical server.
· An RDS host has the Microsoft Remote Desktop Services role, the Microsoft Remote Desktop Session Host service, and Horizon Agent installed. Remote Desktop Services was previously known as Terminal Services. The Remote Desktop Session Host service allows a server to host applications and remote desktop sessions. With Horizon Agent installed on an RDS host, users can connect to applications and desktop sessions by using the display protocol PCoIP or Blast Extreme. Both protocols provide an optimized user experience for the delivery of remote content, including images, audio and video.
· The performance of an RDS host depends on many factors. For information on how to tune the performance of different versions of Windows Server, see http://msdn.microsoft.com/library/windows/hardware/gg463392.aspx.
· Horizon 7 supports at most one desktop session and one application session per user on an RDS host.
· When users submit print jobs concurrently from RDS desktops or applications that are hosted on the same RDS host, the ThinPrint server on the RDS host processes the print requests serially rather than in parallel. This can cause a delay for some users. Note that the print server does not wait for a print job to complete before processing the next one. Print jobs that are sent to different printers will print in parallel.
· If a user launches an application and also an RDS desktop, and both are hosted on the same RDS host, they share the same user profile. If the user launches an application from the desktop, conflicts may result if both applications try to access or modify the same parts of the user profile, and one of the applications may fail to run properly.
· The process of setting up applications or RDS desktops for remote access involves the following tasks:
· Installing Applications
- If you plan to create application pools, you must install the applications on the RDS hosts. If you want Horizon 7 to automatically display the list of installed applications, you must install the applications so that they are available to all users from the Start menu. You can install an application at any time before you create the application pool. If you plan to manually specify an application, you can install the application at any time, either before or after creating an application pool.
· Important
- When you install an application, you must install it on all the RDS hosts in a farm and in the same location on each RDS host. If you do not, a health warning will appear on the View Administrator dashboard. In such a situation, if you create an application pool, users might encounter an error when they try to run the application.
- When you create an application pool, Horizon 7 automatically displays the applications that are available to all users rather than individual users from the Start menu on all of the RDS hosts in a farm. You can choose any applications from that list. In addition, you can manually specify an application that is not available to all users from the Start menu. There is no limit on the number of applications that you can install on an RDS host.
Farms, RDS Hosts, Desktop and Application Pools
With VMware Horizon, you can create desktop and application pools to give users remote access to virtual machine-based desktops, session-based desktops, physical computers, and applications. Horizon takes advantage of Microsoft Remote Desktop Services (RDS) and VMware PC-over-IP (PCoIP) technologies to provide high-quality remote access to users.
· RDS Hosts
- RDS hosts are server computers that have Windows Remote Desktop Services and View Agent installed. These servers host applications and desktop sessions that users can access remotely. To use RDS desktop pools or applications, your end users must have access to Horizon Client 3.0 or later software.
· Desktop Pools
- There are three types of desktop pools: automated, manual, and RDS. Automated desktop pools use a vCenter Server virtual machine template or snapshot to create a pool of identical virtual machines. Manual desktop pools are a collection of existing vCenter Server virtual machines, physical computers, or third-party virtual machines. In automated or manual pools, each machine is available for one user to access remotely at a time. RDS desktop pools are not a collection of machines, but instead, provide users with desktop sessions on RDS hosts. Multiple users can have desktop sessions on an RDS host simultaneously.
· Application Pools
- Application pools let you deliver applications to many users. The applications in application pools run on a farm of RDS hosts.
· Farms
- Farms are collections of RDS hosts and facilitate the management of those hosts. Farms can have a variable number of RDS hosts and provide a common set of applications or RDS desktops to users. When you create an RDS desktop pool or an application pool, you must specify a farm. The RDS hosts in the farm provide desktop and application sessions to users.
Figure 33 VMware Horizon Architectural Overview
Architecture and Design of VMware Horizon on Cisco Unified Computing System and Cisco HyperFlex System Design Fundamentals
There are many reasons to consider a virtual desktop solution such as an ever growing and diverse base of user devices, complexity in management of traditional desktops, security, and even Bring Your Own Computer (BYOC) to work programs. The first step in designing a virtual desktop solution is to understand the user community and the type of tasks that are required to successfully execute their role. The following sample user classifications are provided:
· Knowledge Workers today do not just work in their offices all day – they attend meetings, visit branch offices, work from home, and even coffee shops. These anywhere workers expect access to all of their same applications and data wherever they are.
· External Contractors are increasingly part of your everyday business. They need access to certain portions of your applications and data, yet administrators still have little control over the devices they use and the locations they work from. Consequently, IT is stuck making trade-offs on the cost of providing these workers a device vs. the security risk of allowing them access from their own devices.
· Task Workers perform a set of well-defined tasks. These workers access a small set of applications and have limited requirements from their PCs. However, since these workers are interacting with your customers, partners, and employees, they have access to your most critical data.
· Mobile Workers need access to their virtual desktop from everywhere, regardless of their ability to connect to a network. In addition, these workers expect the ability to personalize their PCs, by installing their own applications and storing their own data, such as photos and music, on these devices.
· Shared Workstation users are often found in state-of-the-art university and business computer labs, conference rooms or training centers. Shared workstation environments have the constant requirement to re-provision desktops with the latest operating systems and applications as the needs of the organization change, tops the list.
After the user classifications have been identified and the business requirements for each user classification have been defined, it becomes essential to evaluate the types of virtual desktops that are needed based on user requirements. There are essentially five potential desktops environments for each user:
· Traditional PC: A traditional PC is what ―typically‖ constituted a desktop environment: physical device with a locally installed operating system.
· Hosted Shared Desktop: A hosted, server-based desktop is a desktop where the user interacts through a delivery protocol. With hosted, server-based desktops, a single installed instance of a server operating system, such as Microsoft Windows Server 2012, is shared by multiple users simultaneously. Each user receives a desktop "session" and works in an isolated memory space. Changes made by one user could impact the other users.
· Hosted Virtual Desktop: A hosted virtual desktop is a virtual desktop running either on virtualization layer (ESX) or on bare metal hardware. The user does not work with and sit in front of the desktop, but instead the user interacts through a delivery protocol.
· Published Applications: Published applications run entirely on the VMware RDSH Session Hosts and the user interacts through a delivery protocol. With published applications, a single installed instance of an application, such as Microsoft, is shared by multiple users simultaneously. Each user receives an application "session" and works in an isolated memory space.
· Streamed Applications: Streamed desktops and applications run entirely on the user‘s local client device and are sent from a server on demand. The user interacts with the application or desktop directly but the resources may only available while they are connected to the network.
· Local Virtual Desktop: A local virtual desktop is a desktop running entirely on the user‘s local device and continues to operate when disconnected from the network. In this case, the user’s local device is used as a type 1 hypervisor and is synced with the data center when the device is connected to the network.
For the purposes of the validation represented in this document both Horizon Virtual Desktops and Remote Desktop sever Hosted Sessions were validated. Each of the sections provides some fundamental design decisions for this environment.
Understanding Applications and Data
When the desktop user groups and sub-groups have been identified, the next task is to catalog group application and data requirements. This can be one of the most time-consuming processes in the VDI planning exercise, but is essential for the VDI project’s success. If the applications and data are not identified and co-located, performance will be negatively affected.
The process of analyzing the variety of application and data pairs for an organization will likely be complicated by the inclusion cloud applications, like SalesForce.com. This application and data analysis is beyond the scope of this Cisco Validated Design, but should not be omitted from the planning process. There are a variety of third party tools available to assist organizations with this crucial exercise.
Project Planning and Solution Sizing Sample Questions
Now that user groups, their applications and their data requirements are understood, some key project and solution sizing questions may be considered.
General project questions should be addressed at the outset, including:
· Has a VDI pilot plan been created based on the business analysis of the desktop groups, applications and data?
· Is there infrastructure and budget in place to run the pilot program?
· Are the required skill sets to execute the VDI project available? Can we hire or contract for them?
· Do we have end user experience performance metrics identified for each desktop sub-group?
· How will we measure success or failure?
· What is the future implication of success or failure?
Below is a short, non-exhaustive list of sizing questions that should be addressed for each user sub-group:
· What is the desktop OS planned? Windows 7, Windows 8, or Windows 10?
· 32-bit or 64-bit desktop OS?
· How many virtual desktops will be deployed in the pilot? In production? All Windows 7/8/10?
· How much memory per target desktop group desktop?
· Are there any rich media, Flash, or graphics-intensive workloads?
· What is the end point graphics processing capability?
· Will VMware RDSH for Remote Desktop Server Hosted Sessions used?
· What is the hypervisor for the solution?
· What is the storage configuration in the existing environment?
· Are there sufficient IOPS available for the write-intensive VDI workload?
· Will there be storage dedicated and tuned for VDI service?
· Is there a voice component to the desktop?
· Is anti-virus a part of the image?
· Is user profile management (e.g., non-roaming profile based) part of the solution?
· What is the fault tolerance, failover, disaster recovery plan?
· Are there additional desktop sub-group specific questions?
Desktop Virtualization Design Fundamentals
An ever growing and diverse base of user devices, complexity in management of traditional desktops, security, and even Bring Your Own Device (BYOD) to work programs are prime reasons for moving to a virtual desktop solution.
VMware Horizon Design Fundamentals
VMware Horizon 7 integrates Remote Desktop Server Hosted sessions users and VDI desktop virtualization technologies into a unified architecture that enables a scalable, simple, efficient, mixed users and manageable solution for delivering Windows applications and desktops as a service.
Users can select applications from an easy-to-use “store” that is accessible from tablets, smartphones, PCs, Macs, and thin clients. VMware Horizon delivers a native touch-optimized experience via PCoIP or Blast Extreme high-definition performance, even over mobile networks.
Horizon VDI Pool and RDSH Servers Pool
Collections of identical Virtual Machines (VMs) or physical computers are managed as a single entity called a Desktop Pool. In this CVD, VM provisioning relies on VMware View Composer aligning with VMware Horizon View Connection Server and vCenter Server components. Machines in these Pools are configured to run either a Windows Server 2012 OS (for RDSH hosted shared sessions) or a Windows 10 Desktop OS (for linked clone, instant clone and persistent VDI desktops).
Server OS and Desktop OS Machines were configured in this CVD to support RDSH hosted shared desktops and a variety of VDI hosted virtual desktops.
Figure 34 VMware Horizon Design Overview
Figure 35 Horizon VDI and RDSH desktop Delivery based on display protocol (PCoIP/Blast/RDP)
VMware Horizon Composer
VMware Horizon Composer is a feature in Horizon that gives administrators the ability to manage virtual machine pools or the desktop pools that share a common virtual disk. An administrator can update the master image, then all desktops using linked clones of that master image can also be patched. Updating the master image will patch the cloned desktops of the users without touching their applications, data or settings.
The VMware View Composer pooled desktops solution’s infrastructure is based on software-streaming technology. After creating and configuring the Master Image for a virtual desktop pool, a snapshot is taken of the OS and applications that is accessible to host(s).
Figure 36 VMware Horizon Composer Overview
VMware View Storage Accelerator
VMware View Storage Accelerator is an in-memory host caching capability that uses the content-based read cache (CBRC) feature in ESXi hosts. CBRC provides a per-host RAM-based solution for View desktops, which greatly reduces the number of read I/O requests that are issued to the storage layer. It also addresses boot storms—when multiple virtual desktops are booted at the same time—which can cause a large number of read operations. CBRC is beneficial when administrators or users load applications or data frequently. Note that CBRC was used in all tests that were performed on the solution described here: Horizon running pooled linked-clone desktops hosted on Cisco HyperFlex system.
Multiple Site Configuration
If you have multiple regional sites, you can use any of the Load Balances Tools (Ex:- Big-IP Global Traffic Manager) to direct the user connections to the most appropriate site to deliver the desktops and application to users.
In Figure 37, The image depicting sites, a site was created in two data centers. Having two sites globally, rather than just one, minimizes the amount of unnecessary WAN traffic. Two Cisco blade servers host the required infrastructure services (Domain Controllers, DNS, DHCP, Profile, SQL, VMware Horizon View Connection Servers, View Composer server and web servers).
Figure 37 Multisite Configuration Overview
Based on the requirement and no of data centers or remote location, we can chose any of the available Load balancing software or tools accelerates the application performance, load balances servers, increases security, and optimizes the user experience. In this example, two Big-IP Local Traffic Manager are used to provide a high availability configuration.
BIG-IP Local Traffic Manager has been shown as example for presentation purpose.
Designing a VMware Horizon Environment for Various Workload Types
With VMware Horizon 7, the method you choose to provide applications or desktops to users depends on the types of applications and desktops you are hosting and available system resources, as well as the types of users and user experience you want to provide.
| Desktop OS machines
|
You want: A client-based application delivery solution that is secure, provides centralized management, and supports a large number of users per host server (or hypervisor), while providing users with applications that display seamlessly in high-definition. Your users: Are internal, external contractors, third-party collaborators, and other provisional team members. Users do not require off-line access to hosted applications. Application types: Applications that might not work well with other applications or might interact with the operating system, such as .NET framework. These types of applications are ideal for hosting on virtual machines. Applications running on older operating systems such as Windows XP or Windows Vista, and older architectures, such as 32-bit or 16-bit. By isolating each application on its own virtual machine, if one machine fails, it does not impact other users. |
| Remote PC Access
|
You want: Employees with secure remote access to a physical computer without using a VPN. For example, the user may be accessing their physical desktop PC from home or through a public WIFI hotspot. Depending upon the location, you may want to restrict the ability to print or copy and paste outside of the desktop. This method enables BYO device support without migrating desktop images into the datacenter. Your users: Employees or contractors that have the option to work from home, but need access to specific software or data on their corporate desktops to perform their jobs remotely. Host: The same as Desktop OS machines. Application types: Applications that are delivered from an office computer and display seamlessly in high definition on the remote user's device. |
For the Cisco Validated Design described in this document, individual configuration of Remote Desktop Server Hosted sessions (RDSH) using RDS-based Server OS machines and Hosted Virtual Desktops (HVDs) using Desktop OS machines via Linked-clone and Instant-clone automated pool were configured and tested. The following sections discuss design decisions relative to the VMware Horizon deployment, including the CVD test environment.
Products Deployed
The architecture deployed is highly modular. While each customer’s environment might vary in its exact configuration, the reference architecture contained in this document once built, can easily be scaled as requirements and demands change. This includes scaling both up (adding additional resources within existing Cisco HyperFlex system) and out (adding additional Cisco UCS HX-series nodes).
The solution includes Cisco networking, Cisco UCS and Cisco HyperFlex hyper-converged storage, which efficiently fits into a single data center rack, including the access layer network switches.
This validated design document details the deployment of the multiple configurations extending to 2000 or 2400 users for Horizon virtual desktop or Horizon RDSH published desktop workload respectively featuring the following software:
· VMware Horizon 7 Shared Remote Desktop Server Hosted (RDSH) sessions on Cisco HyperFlex
· VMware Horizon 7 Non-Persistent Virtual Desktops (VDI) on Cisco HyperFlex
· Microsoft Windows Server 2016 for User Profile Manager
· Microsoft Windows 2016 Server for Login VSI Management and data servers to simulate real world VDI workload
· VMware vSphere ESXi 6.0 Update 3 Hypervisor

This document is intended to allow you to fully configure your environment. In this process, various steps require you to insert customer-specific naming conventions, IP addresses, and VLAN schemes, as well as to record appropriate MAC addresses. Table 2 through Table 6 lists the information you need to configure your environment.
VLANs
The VLAN configuration recommended for the environment includes a total of seven VLANs as outlined in Error! Reference source not found.2.

A dedicated network or subnet for physical device management is often used in datacenters. In this scenario, the mgmt0 interfaces of the two Fabric Interconnects would be connected to that dedicated network or subnet. This is a valid configuration for HyperFlex installations with the following caveat; wherever the HyperFlex installer is deployed it must have IP connectivity to the subnet of the mgmt0 interfaces of the Fabric Interconnects, and also have IP connectivity to the subnets used by the hx-inband-mgmt VLANs listed above.
Jumbo Frames
All HyperFlex storage traffic traversing the hx-storage-data VLAN and subnet is configured to use jumbo frames, or to be precise all communication is configured to send IP packets with a Maximum Transmission Unit (MTU) size of 9000 bytes. Using a larger MTU value means that each IP packet sent carries a larger payload, therefore transmitting more data per packet, and consequently sending and receiving data faster. This requirement also means that the Cisco UCS uplinks must be configured to pass jumbo frames. Failure to configure the Cisco UCS uplink switches to allow jumbo frames can lead to service interruptions during some failure scenarios, particularly when cable or port failures would cause storage traffic to traverse the northbound Cisco UCS uplink switches.
VMware Clusters
Three VMware Clusters were configured in one vCenter datacenter instance to support the solution and testing environment:
· Infrastructure Cluster: Infrastructure VMs (vCenter, Active Directory, DNS, DHCP, SQL Server, VMware Connection Servers, VMware Replica Servers, View Composer Server, Cisco Nexus 1000v Virtual Supervisor Module, and VSMs, etc.)
· HyperFlex Cluster: VMware Horizon RDSH VMs (Windows Server 2016) or Persistent/Non-Persistent VDI VM Pools (Windows 10 64-bit)
HyperFlex release v2.0 supports 32 nodes in single VMware cluster with sixteen HXAF series HXAF220 or HXAF240 and sixteen compute-only node.
· VSI Launcher Cluster: Login VSI Cluster (The Login VSI launcher infrastructure was connected using the same set of switches and vCenter instance, but was hosted on separate local storage and servers.)

ESXi Host Design
The following sections detail the design of the elements within the VMware ESXi hypervisors, system requirements, virtual networking and the configuration of ESXi for the Cisco HyperFlex HX Distributed Data Platform.
Virtual Networking Design
The Cisco HyperFlex system has a pre-defined virtual network design at the ESXi hypervisor level. Four different virtual switches are created by the HyperFlex installer, each using two uplinks, which are each serviced by a vNIC defined in the UCS service profile. The vSwitches created are:
· vswitch-hx-inband-mgmt: This is the default vSwitch0 which is renamed by the ESXi kickstart file as part of the automated installation. The default vmkernel port, vmk0, is configured in the standard Management Network port group. The switch has two uplinks, active on fabric A and standby on fabric B, without jumbo frames. A second port group is created for the Storage Platform Controller VMs to connect to with their individual management interfaces. The VLAN is not a Native VLAN as assigned to the vNIC template, and therefore assigned in ESXi/vSphere
· vswitch-hx-storage-data: This vSwitch is created as part of the automated installation. A vmkernel port, vmk1, is configured in the Storage Hypervisor Data Network port group, which is the interface used for connectivity to the HX Datastores via NFS. The switch has two uplinks, active on fabric B and standby on fabric A, with jumbo frames required. A second port group is created for the Storage Platform Controller VMs to connect to with their individual storage interfaces. The VLAN is not a Native VLAN as assigned to the vNIC template, and therefore assigned in ESXi/vSphere
· vswitch-hx-vm-network: This vSwitch is created as part of the automated installation. The switch has two uplinks, active on both fabrics A and B, and without jumbo frames. The VLAN is not a Native VLAN as assigned to the vNIC template, and therefore assigned in ESXi/vSphere
· vmotion: This vSwitch is created as part of the automated installation. The switch has two uplinks, active on fabric A and standby on fabric B, with jumbo frames required. The VLAN is not a Native VLAN as assigned to the vNIC template, and therefore assigned in ESXi/vSphere
The following table and figures help give more details into the ESXi virtual networking design as built by the HyperFlex installer:

VMDirectPath I/O Pass-through
VMDirectPath I/O allows a guest VM to directly access PCI and PCIe devices in an ESXi host as though they were physical devices belonging to the VM itself, also referred to as PCI pass-through. With the appropriate driver for the hardware device, the guest VM sends all I/O requests directly to the physical device, bypassing the hypervisor. In the Cisco HyperFlex system, the Storage Platform Controller VMs use this feature to gain full control of the Cisco 12Gbps SAS HBA cards in the Cisco HX-series rack-mount servers. This gives the controller VMs direct hardware level access to the physical disks installed in the servers, which they consume to construct the Cisco HX Distributed Filesystem. Only the disks connected directly to the Cisco SAS HBA or to a SAS extender, in turn connected to the SAS HBA are controlled by the controller VMs. Other disks, connected to different controllers, such as the SD cards, remain under the control of the ESXi hypervisor. The configuration of the VMDirectPath I/O feature is done by the Cisco HyperFlex installer, and requires no manual steps.
Storage Platform Controller Virtual Machines
A key component of the Cisco HyperFlex system is the Storage Platform Controller Virtual Machine running on each of the nodes in the HyperFlex cluster. The controller VMs cooperate to form and coordinate the Cisco HX Distributed Filesystem, and service all the guest VM IO requests. The controller VMs are deployed as a vSphere ESXi agent, which is similar in concept to that of a Linux or Windows service. ESXi agents are tied to a specific host, they start and stop along with the ESXi hypervisor, and the system is not considered to be online and ready until both the hypervisor and the agents have started. Each ESXi hypervisor host has a single ESXi agent deployed, which is the controller VM for that node, and it cannot be moved or migrated to another host. The collective ESXi agents are managed via an ESXi agency in the vSphere cluster.
The storage controller VM runs custom software and services that manage and maintain the Cisco HX Distributed Filesystem. The services and processes that run within the controller VMs are not exposed as part of the ESXi agents to the agency, therefore the ESXi hypervisors nor vCenter server have any direct knowledge of the storage services provided by the controller VMs. Management and visibility into the function of the controller VMs, and the Cisco HX Distributed Filesystem is done via a plugin installed to the vCenter server or appliance managing the vSphere cluster. The plugin communicates directly with the controller VMs to display the information requested, or make the configuration changes directed, all while operating within the same web-based interface of the vSphere Web Client. The deployment of the controller VMs, agents, agency, and vCenter plugin are all done by the Cisco HyperFlex installer, and requires no manual steps.
Controller VM Locations
The physical storage location of the controller VMs differs between the Cisco HXAF220c-M4S and HXAF240c-M4SX model servers, due to differences with the physical disk location and connections on the two models of servers. The storage controller VM is operationally no different from any other typical virtual machines in an ESXi environment. The VM must have a virtual disk with the bootable root filesystem available in a location separate from the SAS HBA that the VM is controlling via VMDirectPath I/O. The configuration details of the models are as follows:
· HX220c/HXAF220c: The controller VM’s root filesystem is stored on a 2.2 GB virtual disk, /dev/sda, which is placed on a 3.5 GB VMFS datastore, and that datastore is provisioned from the internal mirrored SD cards. The controller VM has full control of all the front facing hot-swappable disks via PCI pass-through control of the SAS HBA. The controller VM operating system sees the 120 GB SSD, also commonly called the “housekeeping” disk as /dev/sdb, and places HyperFlex binaries, logs, and zookeeper partitions on this disk. The remaining disks seen by the controller VM OS are used by the HX Distributed filesystem for caching and capacity layers.
· HX240c/HXAF240c: The HX240c-M4SX or HXAF240c-M4SXserver has a built-in SATA controller provided by the Intel Wellsburg Platform Controller Hub (PCH) chip, and the 120 GB housekeeping disk is connected to it, placed in an internal drive carrier. Since this model does not connect the 120 GB housekeeping disk to the SAS HBA, the ESXi hypervisor remains in control of this disk, and a VMFS datastore is provisioned there, using the entire disk. On this VMFS datastore, a 2.2 GB virtual disk is created and used by the controller VM as /dev/sda for the root filesystem, and an 87 GB virtual disk is created and used by the controller VM as /dev/sdb, placing the HyperFlex binaries, logs, and zookeeper partitions on this disk. The front-facing hot swappable disks, seen by the controller VM OS through PCI pass-through control of the SAS HBA, are used by the HX Distributed filesystem for caching and capacity layers.
The following figures detail the Storage Platform Controller VM placement on the ESXi hypervisor hosts.
Figure 42 HX220c or HXAF220c Controller VM Placement
The Cisco UCS B200-M4 compute-only blades also place a lightweight storage controller VM on a 3.5 GB VMFS datastore, provisioned from the SD cards.
Figure 43 HX240c or HXAF20c Controller VM Placement
Cisco HyperFlex Datastores
The new HyperFlex cluster has no default datastores configured for virtual machine storage, therefore the datastores must be created using the vCenter Web Client plugin. A minimum of two datastores is recommended to satisfy vSphere High Availability datastore heartbeat requirements, although one of the two datastores can be very small. It is important to recognize that all HyperFlex datastores are thinly provisioned, meaning that their configured size can far exceed the actual space available in the HyperFlex cluster. Alerts will be raised by the HyperFlex system in the vCenter plugin when actual space consumption results in low amounts of free space, and alerts will be sent via auto support email alerts. Overall space consumption in the HyperFlex clustered filesystem is optimized by the default deduplication and compression features.
Figure 44 Datastore Example
CPU Resource Reservations
Since the storage controller VMs provide critical functionality of the Cisco HX Distributed Data Platform, the HyperFlex installer will configure CPU resource reservations for the controller VMs. This reservation guarantees that the controller VMs will have CPU resources at a minimum level, in situations where the physical CPU resources of the ESXi hypervisor host are being heavily consumed by the guest VMs. Table 4 details the CPU resource reservation of the storage controller VMs:

Memory Resource Reservations
Since the storage controller VMs provide critical functionality of the Cisco HX Distributed Data Platform, the HyperFlex installer will configure memory resource reservations for the controller VMs. This reservation guarantees that the controller VMs will have memory resources at a minimum level, in situations where the physical memory resources of the ESXi hypervisor host are being heavily consumed by the guest VMs.
Table 5 details the memory resource reservation of the storage controller VMs.

Cisco Unified Computing System Configuration
This section details the Cisco UCS configuration performed as part of the infrastructure build out by the Cisco HyperFlex installer. Many of the configuration elements are fixed in nature, meanwhile the HyperFlex installer does allow for some items to be specified at the time of creation, for example VLAN names and IDs, IP pools and more. Where the elements can be manually set during the installation, those items will be noted in << >> brackets.
For complete detail on racking, power, and installation of the chassis is described in the install guide (see www.cisco.com/c/en/us/support/servers-unified-computing/ucs-manager/products-installation-guides-list.html) and it is beyond the scope of this document. For more information about each step, refer to the following documents: Cisco UCS Manager Configuration Guides – GUI and Command Line Interface (CLI) Cisco UCS Manager - Configuration Guides - Cisco
During the HyperFlex Installation a Cisco UCS Sub-Organization is created named “hx-cluster”. The sub-organization is created below the root level of the Cisco UCS hierarchy, and is used to contain all policies, pools, templates and service profiles used by HyperFlex. This arrangement allows for organizational control using Role-Based Access Control (RBAC) and administrative locales at a later time if desired. In this way, control can be granted to administrators of only the HyperFlex specific elements of the Cisco UCS domain, separate from control of root level elements or elements in other sub-organizations.
Figure 47 Cisco UCS Manager Configuration: HyperFlex Sub-organization
Deploy and Configure HyperFlex Data Platform
Prerequisites
To deploy and configure the HyperFlex Data Platform, complete the following prerequisites:
1. Set Time Zone and NTP: From the Cisco UCS Manager, from the Admin tab, Configure TimeZone and add NTP server. Save changes.
2. Configure Server Ports: Under the Equipment tab, Select Fabric A, select port to be configured as server port to manager HyperFlex rack server through Cisco UCS Manager.
3. Repeat this step to configure server port on Fabric B.
4. Configure Uplink Ports: On Fabric A, Select port to be configured as uplink port for network connectivity to north bound switch.
5. Repeat this same on Fabric B.
6. Create Port Channels: Under LAN tab, select expand LAN > LAN cloud > Fabric A. Right-click Port Channel.
7. Select Create port-channel to connect with upstream switch as per Cisco UCS best practice. For our reference architecture, we connected a pair of Nexus 9372PX switches.
8. Enter port-channel ID number and name to be created, click Next.
9. Select uplink ports to add as part of the port-channel.
10. Click Finish.
11. Follow the previous steps to create the port-channel on Fabric B, using a different port-channel ID.
12. Configure QoS System Classes: From the LAN tab, below the Lan Cloud node, select QoS system class and configure the Platinum through Bronze system classes as shown in the following figure.
- Set MTU to 9216 for Platinum (Storage data) and Bronze (vMotion)
- Uncheck Enable Packet drop on the Platinum class
- Set Weight for Platinum and Gold priority class to 4 and everything else as best-effort.
- Enable multicast for silver class.
13. Verify UCS Manager Software Version. In the Equipment tab, select Firmware Management > Installed Firmware.
14. Check and verify, both Fabric Interconnects and Cisco USC Manager are configure with Cisco UCS Manager v3.1.2g.
It is recommended to let the HX Installer handle upgrading the server firmware automatically as designed. This will occur once the service profiles are applied to the HX nodes during the automated deployment process.
15. Optional: If you are familiar with Cisco UCS Manager or you wish to break the install into smaller pieces, you can use the server auto firmware download to pre-stage the correct firmware on the nodes. This will speed up the association time in the HyperFlex installer at the cost of running two separate reboot operations. This method is not required or recommended if doing the install in one sitting.
Deploy Cisco HyperFlex Data Platform Installer VM
Download latest installer OVA from Cisco.com. Software Download Link:
Deploy OVA to an existing host in the environment. Use either your existing vCenter Thick Client (C#) or vSphere Web Client to deploy OVA on ESXi host. This document outlines the procedure to deploy the OVA from the web client.
To deploy the OVA from the web client, complete the following steps:
1. Log into vCenter web client via login to web browser with vCenter management IP address: https://<FQDN or IP address for VC>:9443/vcenter-client
2. Select ESXi host under hosts and cluster when HyperFlex data platform installer VM to deploy.
3. Right-click ESXi host, select Deploy OVF Template.
4. Follow the deployment steps to configure HyperFlex data-platform installer VM deployment.
5. Select OVA file to deploy, click Next.
6. Review and verify the details for OVF template to deploy, click Next.
7. Enter name for OVF to template deploy, select datacenter and folder location. Click Next.
8. Select virtual disk format, VM storage policy set to datastore default, select datastore for OVF deployment. Click Next.
9. Select Network adapter destination port-group.
10. Fill out the parameters requested for hostname, gateway, DNS, IP address, and netmask. Alternatively, leave all blank for a DHCP assigned address.
Provide a single DNS server only. Inputting multiple DNS servers will cause queries to fail. You must connect to vCenter to deploy the OVA file and provide the IP address properties. Deploying directly from an ESXi host will not allow you to set these values correctly.
If you have internal firewall rules between these networks, please contact TAC for assistance.
If required, an additional network adapter can be added to the HyperFlex Platform Installer VM after OVF deployment is completed successfully. For example, in case of a separate Inband and Out-Of-Mgmt network, see the screenshot below:
11. Review settings selected part of the OVF deployment, click the check box for Power on after deployment. Click Finish.

3. Click Configure.
4. Enter the Details for the Cisco UCS Manager Configuration:
a. Enter VLAN ID for hx-inband-mgmt, hx-storage-data, hx-vmotion, vm-network.
b. MAC Pool Prefix: The prefix to use for each HX MAC address pool. Please select a prerfix that does not conflict with any other MAC address pool across all Cisco UCS domains.
c. The blocks in the MAC address pool will have the following format:
${prefix}:${fabric_id}${vnic_id}:{service_profile_id}
The first three bytes should always be “00:25:B5.”
5. Enter range of IP address to create a block of IP addresses for external management and access to CIMC/KVM.
6. Cisco UCS firmware version is set to 3.1(2g) which is the required Cisco UCS Manager release for HyperFlex v2.1.1 installation.
7. Enter HyperFlex cluster name.
8. Enter Org name to be created in Cisco UCS Manager.

Three additional columns appear on this page:
· Storage Controller/Management
· Hypervisor/Data
· Storage Controller/Data
The Data network IP addresses are for vmkernel addresses for storage access by the hypervisor and storage controller virtual machine.
1. On the IP Addresses page, check the box Make IP Addresses Sequential or enter the IP address manually for each node for the following requested values:
- Storage Controller/Management
- Hypervisor/Data

5. The configuration details can be exported to a JSON file by clicking the down arrow icon in the top right corner of the Web browser page as shown in the screenshot below.
6. Configuration details can be reviewed on Configuration page on right side section. Verify entered details for IP address entered in Credentials page, server selection for cluster deployment and creation workflow, Cisco UCS Manager configuration, Hypervisor Configuration, IP addresses.
7. Click Start after verifying details.
When the installation workflow begins, it will go through the Cisco UCS Manager validation.
8. After a successful validation, the workflow continues with the Cisco UCS Manager configuration.
9. After a successful Cisco UCS Manager configuration, the installer proceeds with the Hypervisor configuration.
10. After a successful Hypervisor configuration, deploy validation task is performed which checks for required compoenent and accessibilty prior Deploy task is performed on Storage Controller VM.
11. Installer performs deployment task after successfully validating Hypervisor configuration.
12. After a successful deployment of the ESXi hosts configuration, the Controller VM software components for HyperFlex installer checks for validation prior to creating the cluster.
13. After a successful validation, the installer creates and starts the HyperFlex cluster service.
14. After a successful HyperFlex Installer VM workflow completion, the installer GUI provides a summary of the cluster that has been created.
Cisco HyperFlex Cluster Expansion
For this exercise, you will add the compute node workflow part of the cluster exansion.
Prerequisite
Configure the service profile for compute-only nodes and install ESXi hypervisor.
To add the compute node workflow, complete the following steps:
1. Login to Cisco UCS Manger.
2. Under “hx-cluster” sub-organization:
a. In the existing vMedia policy “HyperFlex” add vMedia mount details to boot ESXi image from data platform installer VM.
b. For Hostname/IP Address – Add IP address of data-platform installer VM which can alsocommunicate with Cisco UCS Manager.
3. Change the existing service profile template to accommodate the new changes; install ESXi via vMedia policy.
4. In the existing service profile template “compute-nodes” select vMedia Policy tab.
5. Click Modify vMedia Policy.
6. From the drop-down list of vMedia Policy, select HyperFlex.
7. In the existing service profile template “compute-nodes” click Boot Order tab.
8. Click Modify Boot Policy.

Run Cluster Post Installation Script
After a successful installation of HyperFlex cluster, run the post_install script by loging into the Data Platform Installer VM via SSH, using the credentials configured earlier.
A built-in post install script automates basic final configuration tasks like enabling HA/DRS on HyperFlex cluster, configuring vmKernel for vMotion interface, creating datastore for ESXi logging, etc., as shown in the following figures.
1. To run the script, first use your tool of choice to make a secure connection to the Cisco HyperFlex Data Platform installer using it’s IP address and port 22.
2. Authenticate with the credentials provided earlier. (user name: root with password Cisco 123 if you did not change the defaults.)
3. When authenticated, enter post_install at the command prompt, then press Enter.
4. Provide a valid vCenter administrator user name and password and the vCenter url IP address.
5. Type y for yes to each of the promts that follow except Add VM network VLANs? (y/n) where you can choose whether or not to send health status data via SMS to Cisco support.
6. Provide the requested user credentials, the vMotion netmask, VLAN ID and an IP address on the vMotion VLAN for each host when prompted for the vmkernel IP.

Testing Methodology and Success Criteria
All validation testing was conducted on-site within the Cisco labs in San Jose, California.
The testing results focused on the entire process of the virtual desktop lifecycle by capturing metrics during the desktop boot-up, user logon and virtual desktop acquisition (also referred to as ramp-up,) user workload execution (also referred to as steady state), and user logoff for the RDSH Servers Session under test.
Test metrics were gathered from the virtual desktop, storage, and load generation software to assess the overall success of an individual test cycle. Each test cycle was not considered passing unless all of the planned test users completed the ramp-up and steady state phases (described below) and unless all metrics were within the permissible thresholds as noted as success criteria.
Three successfully completed test cycles were conducted for each hardware configuration and results were found to be relatively consistent from one test to the next.
You can obtain additional information and a free test license from http://www.loginvsi.com.
Testing Procedure
The following protocol was used for each test cycle in this study to insure consistent results.
Pre-Test Setup for Testing
All machines were shut down utilizing the VMware Horizon 7 Administrator Console.
All Launchers for the test were shut down. They were then restarted in groups of 10 each minute until the required number of launchers was running with the Login VSI Agent at a “waiting for test to start” state.
Test Run Protocol
To simulate severe, real-world environments, Cisco requires the log-on and start-work sequence, known as Ramp Up, to complete in 48 minutes. Additionally, we require all sessions started, whether 60 single server users or 4000 full scale test users to become active within two minutes after the last session is launched.
In addition, Cisco requires that the Login VSI Benchmark method is used for all single server and scale testing. This assures that our tests represent real-world scenarios. For each of the three consecutive runs on single server tests, the same process was followed. Complete the following steps:
1. Time 0:00:00 Start PerfMon Logging on the following systems:
- Infrastructure and VDI Host Blades used in test run
- All Infrastructure VMs used in test run (AD, SQL, View Connection brokers, image mgmt., etc.)
2. Time 0:00:10 Start Storage Partner Performance Logging on Storage System.
3. Time 0:05: Boot RDS Machines using VMware Horizon 7 Administrator Console.
4. Time 0:06 First machines boot.
5. Time 0:35 Single Server or Scale target number of RDS Servers registered on XD.
No more than 60 Minutes of rest time is allowed after the last desktop is registered and available on VMware Horizon 7 Administrator Console dashboard. Typically a 20-30 minute rest period for Windows 10 desktops and 10 minutes for RDS VMs is sufficient.
6. Time 1:35 Start Login VSI 4.1.25 Knowledge Worker Benchmark Mode Test, setting auto-logoff time at 900 seconds, with Single Server or Scale target number of desktop VMs utilizing sufficient number of Launchers (at 20-25 sessions/Launcher).
7. Time 2:23 Single Server or Scale target number of desktop VMs desktops launched (48 minute benchmark launch rate).
8. Time 2:25 All launched sessions must become active.
All sessions launched must become active for a valid test run within this window.
9. Time 2:40 Login VSI Test Ends (based on Auto Logoff 900 Second period designated above).
10. Time 2:55 All active sessions logged off.
11. All sessions launched and active must be logged off for a valid test run. The VMware Horizon 7 Administrator Dashboard must show that all desktops have been returned to the registered/available state as evidence of this condition being met.
12. Time 2:57 All logging terminated; Test complete.
13. Time 3:15 Copy all log files off to archive; Set virtual desktops to maintenance mode through broker; Shutdown all Windows 7 machines.
14. Time 3:30 Reboot all hypervisors.
15. Time 3:45 Ready for new test sequence.
Success Criteria
Our “pass” criteria for this testing is as follows: Cisco will run tests at a session count levels that effectively utilize the server capacity measured by CPU, memory, storage and network utilization. We use Login VSI version 4.1.25 to launch Knowledge Worker workload sessions. The number of launched sessions must equal active sessions within two minutes of the last session launched in a test as observed on the VSI Management console.
The VMware Horizon Connection Server Dashboard will be monitored throughout the steady state to make sure of the following:
· All running sessions report In Use throughout the steady state
· No sessions move to unregistered, unavailable or available state at any time during steady state
Within 20 minutes of the end of the test, all sessions on all launchers must have logged out automatically and the Login VSI Agent must have shut down. Cisco’s tolerance for Stuck Sessions is 0.5% (half of one percent.) If the Stuck Session count exceeds that value, we identify it as a test failure condition.
Cisco requires three consecutive runs with results within +/-1% variability to pass the Cisco Validated Design performance criteria. For white papers written by partners, two consecutive runs within +/-1% variability are accepted. (All test data from partner run testing must be supplied along with proposed white paper.)
We will publish Cisco Validated Designs with our recommended workload following the process above and will note that we did not reach a VSImax dynamic in our testing.
The purpose of this testing is to provide the data needed to validate VMware Horizon 7 Hosted Shared Desktop with VMware Horizon 7 Composer provisioning using Microsoft Windows Server 2016 sessions on Cisco UCS HXAF220c-M4S, Cisco UCS 220 M4 and Cisco UCS B200 M4 servers.
The information contained in this section provides data points that a customer may reference in designing their own implementations. These validation results are an example of what is possible under the specific environment conditions outlined here, and do not represent the full characterization of VMware products.
Four test sequences, each containing three consecutive test runs generating the same result, were performed to establish system performance and linear scalability.
VSImax 4.1.x Description
The philosophy behind Login VSI is different to conventional benchmarks. In general, most system benchmarks are steady state benchmarks. These benchmarks execute one or multiple processes, and the measured execution time is the outcome of the test. Simply put: the faster the execution time or the bigger the throughput, the faster the system is according to the benchmark.
Login VSI is different in approach. Login VSI is not primarily designed to be a steady state benchmark (however, if needed, Login VSI can act like one). Login VSI was designed to perform benchmarks for SBC or VDI workloads through system saturation. Login VSI loads the system with simulated user workloads using well known desktop applications like Microsoft Office, Internet Explorer and Adobe PDF reader. By gradually increasing the amount of simulated users, the system will eventually be saturated. Once the system is saturated, the response time of the applications will increase significantly. This latency in application response times show a clear indication whether the system is (close to being) overloaded. As a result, by nearly overloading a system it is possible to find out what its true maximum user capacity is.
After a test is performed, the response times can be analyzed to calculate the maximum active session/desktop capacity. Within Login VSI this is calculated as VSImax. When the system is coming closer to its saturation point, response times will rise. When reviewing the average response time it will be clear the response times escalate at saturation point.
This VSImax is the “Virtual Session Index (VSI)”. With Virtual Desktop Infrastructure (VDI) and Terminal Services (RDS) workloads this is valid and useful information. This index simplifies comparisons and makes it possible to understand the true impact of configuration changes on hypervisor host or guest level.
Server-Side Response Time Measurements
It is important to understand why specific Login VSI design choices have been made. An important design choice is to execute the workload directly on the target system within the session instead of using remote sessions. The scripts simulating the workloads are performed by an engine that executes workload scripts on every target system, and are initiated at logon within the simulated user’s desktop session context.
An alternative to the Login VSI method would be to generate user actions client side through the remoting protocol. These methods are always specific to a product and vendor dependent. More importantly, some protocols simply do not have a method to script user actions client side.
For Login VSI the choice has been made to execute the scripts completely server side. This is the only practical and platform independent solutions, for a benchmark like Login VSI.
Calculating VSImax v4.1.x
The simulated desktop workload is scripted in a 48-minute loop when a simulated Login VSI user is logged on, performing generic Office worker activities. After the loop is finished it will restart automatically. Within each loop the response times of sixteen specific operations are measured in a regular interval: sixteen times in within each loop. The response times of these five operations are used to determine VSImax.
The five operations from which the response times are measured are:
· Notepad File Open (NFO)
Loading and initiating VSINotepad.exe and opening the openfile dialog. This operation is handled by the OS and by the VSINotepad.exe itself through execution. This operation seems almost instant from an end-user’s point of view.
· Notepad Start Load (NSLD)
Loading and initiating VSINotepad.exe and opening a file. This operation is also handled by the OS and by the VSINotepad.exe itself through execution. This operation seems almost instant from an end-user’s point of view.
· Zip High Compression (ZHC)
This action copy's a random file and compresses it (with 7zip) with high compression enabled. The compression will very briefly spike CPU and disk IO.
· Zip Low Compression (ZLC)
This action copy's a random file and compresses it (with 7zip) with low compression enabled. The compression will very briefly disk IO and creates some load on the CPU.
· CPU
Calculates a large array of random data and spikes the CPU for a short period of time.
These measured operations within Login VSI do hit considerably different subsystems such as CPU (user and kernel), Memory, Disk, the OS in general, the application itself, print, GDI, etc. These operations are specifically short by nature. When such operations become consistently long: the system is saturated because of excessive queuing on any kind of resource. As a result, the average response times will then escalate. This effect is clearly visible to end-users. If such operations consistently consume multiple seconds the user will regard the system as slow and unresponsive.

Figure 50 Sample of a VSI Test Response Time Graph with a Clear Performance Issue
When the test is finished, VSImax can be calculated. When the system is not saturated, and it could complete the full test without exceeding the average response time latency threshold, VSImax is not reached and the amount of sessions ran successfully.
The response times are very different per measurement type, for instance Zip with compression can be around 2800 ms, while the Zip action without compression can only take 75ms. This response time of these actions are weighted before they are added to the total. This ensures that each activity has an equal impact on the total response time.
In comparison to previous VSImax models, this weighting much better represent system performance. All actions have very similar weight in the VSImax total. The following weighting of the response times are applied.
The following actions are part of the VSImax v4.1 calculation and are weighted as follows (US notation):
· Notepad File Open (NFO): 0.75
· Notepad Start Load (NSLD): 0.2
· Zip High Compression (ZHC): 0.125
· Zip Low Compression (ZLC): 0.2
· CPU: 0.75
This weighting is applied on the baseline and normal Login VSI response times.
With the introduction of Login VSI 4.1 we also created a new method to calculate the base phase of an environment. With the new workloads (Taskworker, Powerworker, etc.) enabling 'base phase' for a more reliable baseline has become obsolete. The calculation is explained below. In total 15 lowest VSI response time samples are taken from the entire test, the lowest 2 samples are removed and the 13 remaining samples are averaged. The result is the Baseline. The calculation is as follows:
· Take the lowest 15 samples of the complete test
· From those 15 samples remove the lowest 2
· Average the 13 results that are left is the baseline
The VSImax average response time in Login VSI 4.1.x is calculated on the amount of active users that are logged on the system.
Always a 5 Login VSI response time samples are averaged + 40% of the amount of “active” sessions. For example, if the active sessions is 60, then latest 5 + 24 (=40% of 60) = 31 response time measurement are used for the average calculation.
To remove noise (accidental spikes) from the calculation, the top 5% and bottom 5% of the VSI response time samples are removed from the average calculation, with a minimum of 1 top and 1 bottom sample. As a result, with 60 active users, the last 31 VSI response time sample are taken. From those 31 samples the top 2 samples are removed and lowest 2 results are removed (5% of 31 = 1.55, rounded to 2). At 60 users the average is then calculated over the 27 remaining results.
VSImax v4.1.x is reached when the VSIbase + a 1000 ms latency threshold is not reached by the average VSI response time result. Depending on the tested system, VSImax response time can grow 2 - 3x the baseline average. In end-user computing, a 3x increase in response time in comparison to the baseline is typically regarded as the maximum performance degradation to be considered acceptable.
In VSImax v4.1.x this latency threshold is fixed to 1000ms, this allows better and fairer comparisons between two different systems, especially when they have different baseline results. Ultimately, in VSImax v4.1.x, the performance of the system is not decided by the total average response time, but by the latency is has under load. For all systems, this is now 1000ms (weighted).
The threshold for the total response time is: average weighted baseline response time + 1000ms.
When the system has a weighted baseline response time average of 1500ms, the maximum average response time may not be greater than 2500ms (1500+1000). If the average baseline is 3000 the maximum average response time may not be greater than 4000ms (3000+1000).
When the threshold is not exceeded by the average VSI response time during the test, VSImax is not hit and the amount of sessions ran successfully. This approach is fundamentally different in comparison to previous VSImax methods, as it was always required to saturate the system beyond VSImax threshold.
Lastly, VSImax v4.1.x is now always reported with the average baseline VSI response time result. For example: “The VSImax v4.1 was 125 with a baseline of 1526ms”. This helps considerably in the comparison of systems and gives a more complete understanding of the system. The baseline performance helps to understand the best performance the system can give to an individual user. VSImax indicates what the total user capacity is for the system. These two are not automatically connected and related:
When a server with a very fast dual core CPU, running at 3.6 GHZ, is compared to a 10 core CPU, running at 2,26 GHZ, the dual core machine will give and individual user better performance than the 10 core machine. This is indicated by the baseline VSI response time. The lower this score is, the better performance an individual user can expect.
However, the server with the slower 10 core CPU will easily have a larger capacity than the faster dual core system. This is indicated by VSImax v4.1.x, and the higher VSImax is, the larger overall user capacity can be expected.
With Login VSI 4.1.x a new VSImax method is introduced: VSImax v4.1. This methodology gives much better insight in system performance and scales to extremely large systems.
Boot Storms
A key performance metric for desktop virtualization environments is the ability to boot the virtual machines quickly and efficiently to minimize user wait time for their desktop.
As part of Cisco’s virtual desktop test protocol, we shut down each virtual machine at the conclusion of a benchmark test. When we run a new test, we cold boot all 4000 desktops and measure the time it takes for the 4000th virtual machine to register as available in the Horizon Administrator console.
The Cisco HyperFlex HXAF220cM4SX, Cisco UCS B200 M4 and Cisco UCS C220 M4 based hybrid cluster running Data Platform version 2.1(1b) software can accomplish this task in 15 minutes as shown in the following charts:
Figure 51 4000 Horizon 7 Instant-Clone, Linked-Clone, Persistent(Full Clone) Windows 10 and Windows Server 2016 RDSH sessions with Office 2016 Virtual Desktops Boot and
Register as Available in less than 15 minutes
Recommended Maximum Workload and Configuration Guidelines
Sixteen Node Cisco HXAF220c-M4S Rack Server, Eight Node Cisco UCS C220 M4 and Eight Node Cisco UCS B200 M4 HyperFlex Cluster
For VMware Horizon 7 RDS Hosted Shared Desktop and Hosted Virtual Desktop use case, the recommended maximum workload was determined based on both Login VSI Knowledge Worker workload end user experience measures and HXAF220c-M4S, Cisco UCS C220 M4 and B200 M4 server operating parameters.
This recommended maximum workload approach allows you to determine the server N+1 fault tolerance load the blade can successfully support in the event of a server outage for maintenance or upgrade.
Our recommendation is that the Login VSI Average Response and VSI Index Average should not exceed the Baseline plus 2000 milliseconds to insure that end-user experience is outstanding. Additionally, during steady state, the processor utilization should average no more than 90-95%.
Memory should never be oversubscribed for Desktop Virtualization workloads.
Callouts have been added throughout the data charts to indicate each phase of testing.
| Test Phase |
Description |
| Boot |
Start all RDS and/or VDI virtual machines at the same time. |
| Login |
The Login VSI phase of test is where sessions are launched and start executing the workload over a 48 minutes duration. |
| Steady state |
The steady state phase is where all users are logged in and performing various workload tasks such as using Microsoft Office, Web browsing, PDF printing, playing videos, and compressing files. |
| Logoff |
Sessions finish executing the Login VSI workload and logoff. |
The recommended maximum workload for a Cisco HyperFlex cluster configured on Cisco HXAF2240c-M4S, Cisco UCS C220 M4 and B200 M4 nodes with E2690 v4 processors and 512GB of RAM for Windows Server 2016Hosted Sessions and persistent/non-persistent Hosted Virtual Desktop users is 4000 sessions with Office 2016 virtual desktops respectively.

This Cisco HyperFlex solution addresses urgent needs of IT by delivering a platform that is cost effective and simple to deploy and manage. The architecture and approach used provides for a flexible and high-performance system with a familiar and consistent management model from Cisco. In addition, the solution offers numerous enterprise-class data management features to deliver the next-generation hyperconverged system.
Only Cisco offers the flexibility to add compute only nodes to a hyperconverged cluster for compute intensive workloads like desktop virtualization. This translates to lower cost for the customer, since no hyperconvergence licensing is required for those nodes.
Delivering responsive, resilient, high performance VMware Horizon 7 provisioned Microsoft Windows 10 Virtual Machines and Microsoft Windows Server for hosted Apps or desktops has many advantages for desktop virtualization administrators.
Virtual desktop end-user experience, as measured by the Login VSI tool in benchmark mode, is outstanding with Intel Broadwell E5-2600 v4 processors and Cisco 2400Mhz memory. In fact, we have set a new industry standard in performance for Desktop Virtualization on a hyper-converged platform.

The following charts delineate performance parameters for the 32-node cluster during a Login VSI 4.1.25 Knowledge Worker workload test on 4000 Horizon 7 deployed user benchmark test.
The performance charts indicates that the HyperFlex All-Flash nodes and compute-only nodes in Hybrid configuration running Data Platform version 2.1(1b) were operating consistently from node to node and well within normal operating parameters for hardware in this class. The data also supports the even distribution of the workload across all 32 servers.
