FlexPod Datacenter Design Elements
FlexPod Datacenter is a unified data center platform composed of Cisco UCS servers, Cisco Nexus network switches, and NetApp storage array elements, as shown in Figure 1. The FlexPod Datacenter modules can be configured to support a variety of applications by mixing and matching the component families and versions to achieve optimal capacity, price, and performance targets. The solution can be scaled by augmenting the elements of a single FlexPod instance and by adding multiple FlexPod Datacenter instances to build numerous solutions for virtualized and nonvirtualized data centers.
Cisco UCS Family
Cisco UCS is a next-generation data center platform that unites computing, networking, and storage access and virtualization into a cohesive server system for superior performance and cost-effectiveness. All resources participate in a unified management domain in an integrated multichassis platform. This platform is composed of Cisco UCS B-Series Blade Servers and C-Series Rack Servers, fabric interconnects blade server chassis, and adapter connectivity. Cisco UCS supports Cisco Data Center Virtual Machine Fabric Extender (VM-FEX) technology.
Cisco UCS Manager device management software enables unified management of the entire computing environment. It provides role-based and policy-based management by using the service profiles of the resources, reducing maintenance overhead.
Cisco UCS Central Software manages global resources to enable central management of multiple Cisco UCS domains within or across data centers.
Cisco UCS fabric interconnects are the communication and management backbone for the Cisco UCS solution, providing LAN and SAN connectivity to the server blades. The fabric interconnects connect the Cisco UCS B-Series and C-Series servers and the blade server chassis to form a unified fabric, which becomes a single management domain, providing high availability and simplicity of management.
Cisco UCS B-Series Blade Servers are an enterprise-class computing platform designed to efficiently deliver a broad range of IT workloads, from web infrastructure to distributed databases.
Cisco UCS C-Series Rack Servers extend the unified computing model to further increase scalability and business agility. The C-Series implements innovative technologies, including a standards-based unified network fabric, support for Cisco VM-FEX virtualization, and Cisco Extended Memory Technology.

Cisco Nexus Switches
The Cisco Nexus family of switches forms the networking foundation for a FlexPod Datacenter deployment. They support any transport over Ethernet, including Layer 2 and Layer 3 traffic and storage traffic, on one common data center-class platform to transform the data center network into a standards-based, multipurpose, multiprotocol, Ethernet-based fabric. They use data center-class Cisco NX-OS software for high reliability and ease of management.
Cisco Nexus 5000 Series Switches are ideal for enterprise-class data center server access and support smaller-scale midmarket data center aggregation layer deployments. The Cisco Nexus 5000 platform is a higher-density, lower-latency switching platform, which can be deployed across a diverse set of traditional, virtualized, and high-performance computing (HPC) data center environments. The 5000 Series also expands Cisco fabric extension technology into the servers and virtual machines (VMs) with Cisco Adapter FEX and Cisco VM-FEX.
For more information about the Cisco Nexus 5000 Series, refer to http://www.cisco.com/en/US/products/ps9670/index.html.
Cisco Nexus 1000v Series Switches provide an extensible architectural platform for VM and cloud networking. Integrated into VMware vSphere ESXi and ESX hypervisors and VMware Cloud Director, they provide policy-based VM connectivity, virtualized network services with Cisco vPath for load balancing, and firewalling.
For more information, refer to
http://www.cisco.com/en/US/products/ps9902/index.html
http://www.cisco.com/en/US/products/ps10785/index.html
Note: The Cisco Nexus 1000v is an optional component and was used in this validation effort. However, the standard VMware vSwitch or a VMware VDS can also be used.
Cisco VM-FEX technology collapses virtual switching and physical switching infrastructure environments into a unified environment to simplify management and improve network security and utilization.
NetApp FAS forms the scalable storage element in a FlexPod Datacenter platform. Using the NetApp Data ONTAP operating system, this FlexPod design supports both the Data ONTAP 7-Mode and Clustered Data ONTAP Mode. Both operating system modes support SAN (Fibre Channel, Fibre Channel over Ethernet [FCoE], iSCSI) and network-attached storage (NAS) (CIFS, NFS), and enable primary and secondary storage in a single unified platform so that all virtual desktop data components can be hosted on the same storage array. Data ONTAP provides superior storage efficiency and data protection through features including SnapMirror, thin provisioning, compression, and deduplication.
This FlexPod Datacenter design uses the NetApp FAS8000 Series unified storage systems. The FAS8000 Series is optimized for scale-out storage infrastructure. It enables business-critical workloads that need massive performance and scalability. It unifies SAN and NAS infrastructures and uses high-performance NVRAM-based memory modules to maximize application throughputs. In addition, it integrates unified target adapter (UTA2) ports for 16-Gbps Fibre Channel, 10 Gigabit Ethernet, or FCoE.

Cisco Validated Design for FlexPod Datacenter
The Cisco Validated Design for FlexPod Datacenter validates the cohesive operation of industry-standard hypervisors and applications running on various FlexPod Datacenter configurations. Figure 2 provides a comprehensive list of supported hypervisors, management, and FlexPod Datacenter design elements and versions.
The highlighted components make up the Cisco Validated Design for FlexPod Datacenter described in this document. The objective of this verification is to functionally validate VMware vSphere 5.5U1 on the latest FlexPod architecture for various hardware and software combinations and provide extendable VMware vSphere-based data center infrastructure for mixed workloads and applications.
The Cisco Validated Design described in this document uses the FlexPod Distinct Uplink Design architecture for validation. This is an end-to-end Ethernet transport system supporting multiple LAN and SAN protocols, including FCoE (which is used by the Cisco Nexus switches and NetApp FAS controllers). It provides a unified 10 Gigabit Ethernet-enabled fabric with dedicated FCoE uplinks and dedicated Ethernet uplinks between the Cisco UCS fabric interconnects and the Nexus switches, and converged connectivity between the NetApp storage devices and multipurpose Nexus switch platforms.
The VMware vSphere 5.5U1 features used in this validation include:
● VMware vSphere FDM technology offering VM resiliency in the event of physical server or guest operating system failures
● VMware Distributed Resource Scheduler (DRS) offering dynamic workload distribution to improve resource utilization
● VMware vSphere ESXi hypervisor providing efficient VM abstraction
● Virtual Machine File System (VMFS), which supports simultaneous memory access for multiple hosts
The FlexPod storage configurations used in this validation effort are:
● FlexPod with NetApp Clustered Data ONTAP mode
● FlexPod with NetApp Data ONTAP 7-mode
Figures 3 and 4 illustrate the FlexPod Distinct Uplink topologies for these configurations and highlight the design elements used in each mode. Note that the configurations of the Cisco UCS and Nexus elements are identical in both topologies. The NetApp FAS controller topology is different—in Clustered Data ONTAP Mode, Cisco Nexus 5596 cluster interconnects are used to network the FAS controllers with the disk storage to create a storage pool. In Data ONTAP 7-Mode, the disk storage connects with the FAS controllers using dedicated links, as shown in Figure 4. The FlexPod design is capable of supporting C-Series rack-mount servers using single-wire management, providing further consolidation of the infrastructure and improved rack-mount server density.
