Data center infrastructure for desktop virtualization and the next-generation virtual workspace

What You Will Learn

An agile and robust data center infrastructure is required to support desktop virtualization. Key issues around performance, capacity and security must be built-in to the data center supporting infrastructure for desktop virtualization to deliver on its promises of simplified operations, data security and reduced desktop TCO. Cisco provides an optimized data center infrastructure for desktop virtualization and a platform for the next-generation virtual workspace, working with industry leaders such as VMware, Citrix, EMC, and NetApp, to address the broadest set of IT and user requirements.

Desktop Virtualization and the Evolving Business Environment

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 globe 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 7.

Figure 1. The Evolving Workplace Landscape

Desktop virtualization has been around for a long time, but it is only recently that organizations have begun to deploy desktop virtualization on a broad basis and across a variety of user profiles. Increased data security and reduced TCO are sighted as primary drivers for this increasing adoption. And while desktop virtualization provides benefits on the IT side of the house, end-user enthusiasm has lagged. End-users have been hesitant to give up the experience and access that a fully functioning desktop or laptop provides. These same users are now demanding access to IT resources from a variety of devices, including smart phones and tablets of their own.
Fortunately for IT, end-users, and the business itself, desktop virtualization has progressed and can now offer a near-native end-user experience on almost any device, while at the same time providing increased control, security, and lower TCO to IT and the business. IT is happy, end-users are happy, and the business benefits via greater productivity and reduced costs.
But today's worker is connected in ways beyond the traditional desktop and most desktop virtualization solutions struggle to deliver a complete end-user experience. End-users utilize not only a traditional desktop computing environment, but also have integrated collaboration and media-rich applications. Cisco identified this need in 2010 and developed an architecture and set of solutions, going beyond traditional desktop virtualization, and integrating communications, collaboration and rich-media support into the Cisco Virtualization Experience Infrastructure (VXI). VXI combines Cisco's leadership in data center, networking and collaboration architectures to deliver the next-generation virtual workspace.

Cisco Data Center Infrastructure for Desktop Virtualization and VXI

Cisco desktop virtualization solutions address the needs of an increasingly mobile and geographically dispersed workforce that is adopting an evolving and expanding suite of heterogeneous end-point devices. Cisco solutions give enterprises a path to pervasive and persistent control and security of virtual desktops, applications, and data delivered through a highly scalable and rapidly deployed infrastructure, while reducing costs. Cisco offers an innovative solution that addresses the evolving business IT environment, including desktop hardware refresh cycles, Microsoft Windows 7 migration, security and compliance initiatives, remote and branch offices and offshore facilities, and mergers and acquisitions.
The foundation of Cisco desktop virtualization solutions and VXI is the Cisco data center infrastructure, which combines best-in-class Cisco and partner products, service offerings, and best practices to deliver a simplified, secure and scalable solution leading to TCO savings and implementation success. Cisco offers the first end-to-end desktop virtualization solution that uses an open platform and architectural approach that includes computing, hypervisor, network, storage, security, and management in a single, cohesive system.

Simplified. Secure. Scalable.

Cisco focuses on three key elements to deliver the best desktop virtualization data center infrastructure and platform for the next-generation virtual workspace: simplification, security and scalability. Through this focus customers will achieve savings and success in their desktop virtualization implementations.

Simplified

Cisco Unified Computing System (Cisco UCS) provides a radical new approach to industry standard computing and provides the heart of the data center infrastructure for desktop virtualization and VXI. Among the many features and benefits of Cisco UCS are the drastic reductions in the number of servers needed and the number of cables per server, and the ability to very quickly 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 service profiles and Cisco storage partners' storage-based cloning. This speeds time to productivity for end-users, improves business agility, and allows IT resources to be allocated to other tasks.
IT tasks are further simplified through reduced management complexity, provided by the highly integrated UCS Manager, along with fewer servers, interfaces, and cables to manage and maintain. This is possible due to the industry leading, highest virtual desktop density per blade of Cisco UCS along with the reduced cabling and port-count due to the unified fabric and unified ports of Cisco UCS and desktop virtualization data center infrastructure.
Simplification also leads to improved and more rapid success of a desktop virtualization implementation. Cisco and its partners - VMware (View), Citrix (XenDesktop), EMC, and NetApp - have developed integrated, validated architectures, including available pre-defined, validated infrastructure packages via VCE Vblock (with EMC storage) or FlexPod (with NetApp storage). There is also very tight integration and testing with all of the leading hypervisors, including VMware vSphere, Citrix XenServer, and Microsoft Hyper-V. There are also services to help plan, deploy, and maintain the Cisco data center infrastructure for desktop virtualization.

Secure

While virtual desktops are inherently more secure than their physical world predecessors, they introduce new security considerations. Mission critical web and application servers using a common infrastructure as virtual desktops can now present a much larger attack surface for corrupted desktops. Inter-virtual-machine traffic now poses a more important security consideration that IT managers need to address, especially in dynamic environments that have virtual machines vMotioning across the 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 Nexus) for desktop virtualization provides stronger 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.
Corporate and end-user data is also better protected with consistent, centralized and improved data management, backup, and retention of desktop data, leading to better corporate compliance and a safer desktop virtualization solution. Cisco data center infrastructure for desktop virtualization and VXI reduces the risk associated with a virtual desktops deployment through its integrated, validated end-to-end architecture based on proven designs and technologies.

Scalable

Growth of a desktop virtualization solution is all but inevitable and it is critical to have a solution that can scale, and scale predictably, with that growth. The Cisco solution supports more virtual 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 service profiles allow for on-demand desktop provisioning and it is as easy to deploy dozens or thousands of additional desktops.
Each additional Cisco UCS server provides near linear performance and utilizes Cisco's patented extended memory technology and unified fabric to avoid desktop virtualization bottlenecks. The high performance, low latency network supports high volumes of virtual desktop traffic, including high resolution video and communications. And Cisco storage partners EMC and NetApp maintain data availability and optimal performance during boot and login storms as part of the Cisco desktop virtualization solution.
Cisco UCS and Nexus data center infrastructure is an ideal platform for growth, with transparent scaling of server, network, and storage resources to support desktop virtualization, VXI, data center applications or cloud computing.

Savings and Success

As demonstrated above, the simplified, secure, scalable Cisco data center infrastructure solution for desktop virtualization will save time and money vs. alternative approaches. There will be faster payback and ongoing savings (better ROI and lower TCO) with the industry's highest virtual desktop density per server, meaning there will be fewer servers needed, reducing both capital (CapEx) and operating (OpEx) costs. There will also be much lower network infrastructure costs, with fewer cables per server and fewer ports required, via the Cisco UCS architecture and unified fabric. And storage costs will be reduced with storage tiering and de-duplication technologies, reducing desktop storage needs by up to 50 percent.
The simplified deployment of Cisco UCS for desktop virtualization speeds time to productivity and enhances business agility. IT staff and end-users are more productive more quickly and the business can react to new opportunities by simply deploying virtual desktops whenever and wherever needed. The high performance Cisco systems and network deliver a near-native end-user experience, allowing users to be productive anytime, anywhere.
The ultimate measure of desktop virtualization for any organization is its efficiency and effectiveness, both in the near- and long-term. The Cisco solution is very efficient - allowing rapid deployment, minimal devices and cabling, and lower costs. The solution is also very effective - providing the services end-users need on their devices of choice while improving IT operations, control and data security. Success is bolstered through Cisco's best-of-breed partnerships with leaders in virtualization and storage, and through tested and validated designs and services to help customers throughout the process. Long-term success is enabled through Cisco's scalable, flexible, secure architecture as the platform for desktop virtualization, which is also a strong platform for VXI, data center applications, and cloud computing.

Solution Components

Cisco's desktop virtualization solution is the first in the industry to bind together the three critical elements of an end-to-end deployment - the end-user, the network, and the data center. It draws on Cisco's architectural advantage to provide a solution that supports a diversity of endpoint devices, extends pervasive security and policy management to each virtual desktop, uses a new and innovative virtualization-optimized stateless server computing model (Cisco UCS), and uses the power of the WAN infrastructure to deliver rich media applications without compromise. These Cisco, partner, and services components combine to deliver the Cisco desktop virtualization and VXI solution (Figure 2).
