The Cisco Unified Computing System™ (Cisco UCS™) is optimized for desktop virtualization workloads. Cisco UCS Solution Accelerator Pak configurations help you easily and quickly deploy desktop virtualization by providing predefined configurations for every type of deployment scenario.
Desktop and application virtualization are increasingly popular ways for enterprises to reduce capital and operating expenses, improve efficiency, increase control, and expand connectivity. With virtual desktops, users can access their desktop images for laptops, thin clients, smartphones, or other devices from hosted, centralized infrastructure in a data center.
Although many enterprises are increasingly turning to desktop virtualization to address the need for increased business agility, risk mitigation, security, and support for bring-your-own-device (BYOD) initiatives, the appropriate infrastructure is critical to make these initiatives successful.
Cisco UCS provides the most optimized foundation for desktop and application virtualization infrastructure. The industry's first unified data center platform, Cisco UCS delivers a converged, programmable infrastructure that simplifies and accelerates enterprise-class application and service deployment in bare-metal, virtualized and cloud-computing environments. Unified, model-based management, end-to-end provisioning, and migration support come together in this next-generation data center platform to accelerate and simplify application deployment, with greater reliability and security.
Cisco UCS provides these important features:
• Integration of Cisco servers and network and I/O resources into one system
• Improvement of enterprise application availability and performance
• Scalability of service delivery to increase business agility
• Streamlining of data center resources to reduce total cost of ownership (TCO)
• Radical reduction in the number of devices requiring setup, management, power, cooling, and cabling
Cisco UCS is changing the economics and performance of server-hosted client computing, delivering a robust, high-performance computing fabric on which desktop virtualization can be deployed.
These are the primary elements of Citrix desktop virtualization architecture:
• Citrix XenDesktop transforms Microsoft Windows desktops into virtual desktops for on-demand services to users on any device.
• Citrix Provisioning Services is commonly used to provision Citrix XenDesktop and XenApp environments.
• Citrix XenApp is an application delivery solution that enables any Microsoft Windows application to be virtualized, centralized, and managed and instantly delivered as a service to users anywhere and on any device.
The Cisco UCS controller node is the management server that hosts the hypervisor management software (such as VMware vCenter, Microsoft System Center Virtual Machine Manager [SCVMM], and Citrix XenCenter), Citrix Provisioning Services, and Citrix XenDesktop and XenApp brokers (Citrix Dynamic Desktop Controllers). It can also house other management tools to support the environment.
The Cisco UCS desktop workload node hosts Microsoft Windows virtual desktops as virtual machines for Citrix XenDesktop deployments or as Microsoft Windows server virtual machines for Citrix XenApp deployments.

The characterization is based on a Microsoft Windows 7, 32-bit, 2-GB system with a knowledge worker user and the server running with 60 to 70 percent utilization. Cisco recommends that you assess and profile customer requirements to correctly size the workload and identify the appropriate configurations.
