Dell Virtual Remote Desktop Reference ArchitectureExecutive SummaryMaintaining traditional physical desktops typically requires time-consuming desk-side visits,reduces user productivity, delays support response, exposes data to increased risk and reducesmobility. While some organizations have the resources to address these concerns, doing so isoften at the expense of more strategic initiatives.Many businesses are interested in implementing some form of desktop virtualization to realizethe benefit of centralized deployment and management of their desktop environment.Centralized deployments at enterprise scale are not without their challenges, often requiringsignificant investment of both time and money to plan and size the infrastructureappropriately. User Experiences often play into the decision, where an appropriately sizedinfrastructure can mean the difference between a successful deployment and a faileddeployment.Dell, Citrix, and Microsoft provide an end-to-end optimized solution for remote, server-hosteddesktop virtualization called Dell Virtual Remote Desktop (VRD). This solution combines Dell’sclient, server, storage, networking hardware, and services with Citrix XenDesktop desktopvirtualization technology and Microsoft’s server virtualization and management infrastructure.Dell VRD provides a desktop replacement that is better than a standard desktop in many waysby centralizing management, making IT resources more efficient, improving data security andcontrol, reducing support times, improving staff mobility, and improving the end-userexperience.This Dell VRD Reference Architecture describes three validated configurations of a virtualinfrastructure hosting desktop workloads. The Reference Architecture enables customers toconsider, evaluate, and select the most suitable Dell virtualization solution configurationaccording to their requirements by providing selection criteria and discussing relevantperformance issues.This end-to-end optimized reference architecture leverages our strong partnership with Citrixand Microsoft to deliver the following benefits: Easier deployment, update, and maintenance – by abstracting the OS, applications,customizations, and data from the physical hardware, IT maintains fewer base images and cancustomize them dynamically, reducing desktop management complexity Faster, cheaper support – centralized maintenance of virtual desktops and the ability toinstantly swap out a failed image means the end of the desk-side visit, faster resolution forproblems, and lower support costs Better security and compliance – without a local installation, no corporate data everneeds to leave the data center, ensuring centralized audit and control to maintain datasecurity and regulatory compliance Improved efficiency & productivity – users can access more powerful environments ornew applications at the click of a mouse, to take advantage of faster processing and newbusiness solutions at the drop of a hatPage 4
Dell Virtual Remote Desktop Reference Architecture Better availability, disaster recovery, and business continuity – virtual desktops can bemigrated in seconds to bypass failing endpoint devices (or even entire locations), maintainingbusiness continuity in the case of minor mechanical problems or even major disasters. Improved workforce flexibility and mobility – workers can access their personal desktopfrom any department or location, even on the road (without carrying a laptop) or from PDAsand wireless devices, and if they change roles can access a new standard virtual desktop inminutes.Introduction and ScopeDell’s Flexible Computing Solutions integrate with your existing IT infrastructure to centralizeend user resources in protected data centers and boost workforce productivity and security.The Virtual Remote Desktop (VRD) model enables the hosting of your desktop on a remoteserver where all the compute takes place. You get access to your virtual desktop from a localdevice, such as a Latitude 13 laptop or an Optiplex FX160.This whitepaper is targeted towards IT organizations and System Integrators to provide ageneral sizing guide and configuration recommendations for the Dell Virtual Remote Desktopsolution powered by Citrix XenDesktop and Microsoft Windows Server 2008 R2. The goal of thiswhite paper is to: Introduce you to the architecture of Citrix XenDesktop with Microsoft Windows Server 2008R2 on Dell hardware configurations.Help you understand the issues related to desktop virtualization across various usagescenarios.Clarify, aid, and simplify the selection of configurations for you.The exact configuration of your hardware, software, and services ingredients can varydepending on your unique business requirements, the intensity of your workload and/or yourfeature preferences. This white paper outlines three validated VRD configurations that reflectthe optimum tradeoffs between system performance, complexity and cost for each virtualdesktop. The smallest configuration is the 250 user configuration. It requires a fairly minimalhardware footprint and is designed with simplicity in mind and focuses on demonstratingbasic functionality. No Shared storage is included in this configuration to minimizecomplexity.The 500 user configuration provides a high degree to design flexibility and is designed tomeet the production level deployment requirements of small and medium businesses.The 1000 user configuration is a full-feature virtualization solution for larger deployments.It is intended as a scalable configuration that can be deployed in increments of 1000 users.The scale out to configuration beyond 1000 users does require minor changes e.g.configuration of the Citrix Provisioning servers for superior image management, but thesechanges are outside the scope of this document.Page 5
Dell Virtual Remote Desktop Reference ArchitectureThis paper describes the features, benefits, and performance implications of eachconfiguration.The scope of this document is limited to Dell Citrix Microsoft VRD solutions only. It defines theconfigurations using Dell servers, storage, and networking components. Custom virtualinfrastructure configurations using workstations/desktops and/or other products are possible,but not described here. Custom configurations for specific customer engagements may havethird party hardware and hence are out of scope, as are software components from othervendors.Dell, Microsoft, and Citrix provide several resources for designing and deploying virtualizationsolutions.

This smaller configurationconsists of nine servers.Three R710 servers, each running Windows Server 2008 R2 Hyper-V server core, are used tosupport up to 250 knowledge worker desktop workloads. 96 GB is the recommended memoryconfiguration for all deployments, assuming 85 VMs per server.Two R510 servers with Windows Server 2008 R2 running provisioning services 5.6 arerecommended for the virtual machine disk images. Provisioning services are expected in allconfigurations; however, in the 250 user configuration, shared storage isn’t expected. Thelocal disk in both provisioning services servers is used for the virtual machine image.Two R710 servers running Windows Server 2008 R2 Hyper-V server core are used to host variousinfrastructure server VMs to include XenDesktop Delivery Controller 4.0, Citrix Web Interface,Citrix License server, SQL server 2008, and Microsoft Systems Center Virtual Machine Manager2008 R2 (System Center Virtual Machine Manager 2008 R2).Two file servers running Windows Server 2008 R2 are expected to be used to serve user datafrom local disk for the user shares.Two optional servers with Windows Server 2008 R2 are tasked with running XenApp 6 to hostadditional applications for the virtual machines.Figure 1.250 user configurationPage 10
Dell Virtual Remote Desktop Reference ArchitectureComponents:Hyper-V Servers: Three R710 2U rack mount servers are recommended for this configuration.Each server is recommended to have two 160GB 7.2K RPM SAS drives in a RAID 1 configurationfor the OS and pagefile. In addition, each server has six 72GB 15K RPM SAS drives in a RAID 5configuration for the virtual machine configuration files, memory files, and client side writecache virtual disks. Three NICs are teamed and configured for virtual machine network(s) andthe remaining NIC is configured for system management.Hyper-V Server CPU: Six core CPUs are recommended in all Hyper-V desktop virtualizationsolutions for maximum virtual desktop scalability.Hyper-V Server Memory: The 96GB RAM provides enough memory to deploy 84 1GB virtualmachines running Microsoft Windows 7 with a knowledge worker workload.Hyper-V Operating System: Windows Server 2008 R2 Hyper-V Server Core is recommended forscalability and stability.Hyper-V Server Networking: The four onboard gigabit NICs provide enough bandwidth tosupport iSCSI target and network traffic, while leaving the remaining PCI-e slot(s) available foradditional peripherals.Provisioning Servers: Two R510 2U rack mount servers are recommended for provisioningservices server configuration. Local storage consists of five 73GB 15K RPM in a RAID 5configuration. Two LUNs are created, one used for the Windows Server 2008 R2 OS, and onefor the vDisks. Two provisioning servers are required for redundancy, and each VM image hasto be maintained separately between the two servers. Client side write cache is used toreduce the size of the storage requirements on the provisioning server and to reduce networktraffic. The write cache is on a virtual hard drive for each VM located on the hard drive arraylocal to the hypervisor.Provisioning Server CPU: CPU utilization is relatively low on the provisioning server, so dualcore CPUs are recommended.Provisioning Server Memory: Memory usage is also low on the provisioning server, so 8GB isrecommended.Provisioning Server Operating System: Windows Server 2008 R2.Provisioning Server Networking: An add-in PCI-e dual port 1GbE network card is required toprovide enough network bandwidth in the R510 for provisioning services.Infrastructure Servers: Two R710 Servers with 32GB of RAM and quad core CPUs arerecommended for the Infrastructure servers. XenDesktop Delivery Controllers, Citrix WebInterface servers, and System Center Virtual Machine Manager 2008 R2 are deployed on theseadditional Hyper-V servers with Cluster Share Volumes for failover capabilities. XenDesktopDelivery Controller requires Windows Server 2003. The other infrastructure server VMs arerecommended to be installed with Windows Server 2008 R2.Page 11
