  1. DV-B308: Optimizing Windows 8 for Virtual Desktop Infrastructure Carl Luberti Premier Field Engineer Microsoft Doug Klokow Solution Architect Microsoft

  2. Session Objectives Microsoft Guidance for Windows 8 Configuration Detailed Review of Component Configuration Recommendations for Performance Testing Approach

  3. Why Windows 8 in VDI? Touch Performance Modern Apps User Experience

  4. Choosing the Right VDI Deployment Type Sessions Pooled VMs Personal VMs • ★ • ★★ • ★★★ • ★★★ • ★★ • ★★★ • ★★ • ★★ • ★★★ • ★★★ • ★ • ★ Personalization Application Compatibility Image Management Cost Effectiveness Good ★ Better ★★ Best ★★★

  5. Key Decisions to Consider

  6. Which Windows Edition for the Guest OS? Windows 8 Professional or Enterprise? “Remote Computers running Windows 8 Enterprise provide the best user experience and support all management features. Therefore, Windows 8 Enterprise is the only supported edition for use with Windows Server 2012 virtual desktop collections (VDI).” Source: http://blogs.msdn.com/b/rds/archive/2012/11/26/remotefx-features-for-windows-8-and-windows-server-2012.aspx

  7. Which Windows Bitwise Edition for the Guest OS? Windows 8 32-bit or 64-bit 32-bit has a smaller footprint on the disk, but can only support 4GB of RAM 64-bit may be selected if physical machines will use the 64-bit edition to avoid multiple application compatibility retesting Recommendation Consider using 64-bit as the default, and 32-bit as optional if technical or business requirements are identified.

  8. Memory Allocation Dynamic memory will handle fluctuating demands for memory within a specified range Recommended Minimum 1GB Maximum based on workload Small -> 1.5 to 2GB Medium -> 2GB to 3GB Large -> 2GB to 4GB (or more) Consider using Blade Servers for Extra Large workloads

  9. Memory Usage Comparison 32-bit 64-bit

  10. Disk Size and Partitions OSDisk drive size of the Virtual Desktop is impacted by the following factors: Pooled versus Personal VDI Pooled range from 22GB to 40GB Personalrange from 40GB to 65GB Virtualization Readiness of Applications Compatibility – can the application be virtualized? Performance – Are there adverse performance impacts associated with a virtualized application versus a traditionally installed MSI? If the application is not virtualized, will it be installed local to the guest VM?

  11. Disk Partitions Using the default install routine will create a 350MB System Reserved drive to store BitLocker data Prevent the creation of this partition during OS installation using MDT 2012 to build the image Utilize the “DoNotCreateExtraPartition=YES” rule to prevent the creation of the “System Reserved” partition. Or use Scripted DISKPART commands….

  12. OSDisk Size for Windows 8 64-bit 32-bit Increase of ~2.2 GB when using 64-bit • Notes • These figures are before optimization efforts are complete • Windows Update was not run, so final used space will be slightly higher

  13. Number of Virtual Processors Default – 1 Virtual Processor Medium Usage – 2 Virtual Processors Heavy Usage – 2 to 4 Virtual Processors Note: Is you are using the Hyper-V hypervisor, fairshare will balance usage of processors to avoid one client consuming all available physical processor bandwidth

  14. Requirements to Support RemoteFX GPU must support DirectX 11 A list of certified GPU’s can be found on the Windows Server Catalog web site – link At present there are 6 NVIDIA cards certified for RemoteFX RDVH or RDSH processor must support SLAT (Second-Level Address Translation) Intel Processors identify this with the term Extended Page Tables (EPT) AMD Processors identify this with the term Nested Page Tables (NPT) VDI guest VMs must use the Windows 8 64-bit WDDM v1.20 driver to prevent rendering issues RDVH or RSDH role service must be enabled on the RemoteFX server to provide RemoteFX in client sessions/VMs

  15. Enabling RemoteFX On the Hyper-V Server Confirm that the WDDM v1.2 driver is selected in the GPU drop down Check the “Use this GPU with RemoteFX”

  16. RICH USER EXPERIENCE Options for GPU on server

  17. Multiple Display Configurations

  28. Automation Tools VDI Optimizer (AutoIT) by Jonathan Bennett Creates a VBScript that can then be run on the machine to configure the settings as defined. The last release date was Aug of 2010, and there are no current plans to update to support Windows 8.

  29. Optimization Resources for VDI Focused on Windows 7 Useful to review tested configuration settings Strong correlation to Windows 8 http://social.technet.microsoft.com/wiki/contents/articles/4495.list-of-resources-on-windows-7-optimization-for-vdi.aspx?wa=wsignin1.0
