The Microsoft Premier Field Engineer (PFE) view on Virtual Desktop (VDI) Density

  • Artigo

For some, VDI is about density. How many guests can we stuff into a host with performance and user experience still at acceptable levels? This script is the clarion call for those, a herald in dark times of performance degradation. It is, the script a couple PFEs wrote…

It makes an image lean but supportable. Fast, quick, usable (of course TEST TEST TEST for your applications and needs).

In a post to follow I will deconstruct the script and HTA to open a discussion on the settings.  Post here:  https://blogs.technet.com/b/jeff_stokes/archive/2012/10/18/deconstructing-the-pfe-vdi-optimization-script.aspx

It comes with both an HTA for on the fly configuration and a straight VBS script for inclusion in deployment or image configuration. And it logs in trace32 format.

Industry feedback is welcome.

This script was created by Carl Luberti, Tanner Slayton, and Jeff Stokes. We are Premier Field Engineers at Microsoft.

The Script and HTA are below.

Thank you.

 

EDIT:  10/24/2013 - Jeff Stokes and Carl Luberti - "Removed Offline File Service disable section at advise of MCS, it is found that the only proper way to disable OFS is to disable via GPO, so apply GPO https://gpsearch.azurewebsites.net/default.aspx?policyid=2061 to your VDI OU instead.

' Before finalizing the image perform the following tasks:
' - Ensure no unwanted startup files by using autoruns.exe from SysInternals
' - Run the Disk Cleanup tool as administrator and delete all temporary files and system restore points (can be automated with this script)
' - Run disk defrag and consolidate free space: defrag c: /v /x
' - Reboot the machine 6 times and wait 120 seconds after logging on before performing the next reboot (boot prefetch training)
' - Run disk defrag and optimize boot files (Windows 7 only): defrag c: /v /b
' - If using a dynamic virtual disk, use the vendor's utilities to perform a "shrink" operation

          - Ensure no unwanted startup files by using autoruns.exe from SysInternals<br>
          - Run the Disk Cleanup tool as administrator and delete all temporary files and system restore points (can be automated with this script)<br>

          - Reboot the machine 6 times and wait 120 seconds after logging on before performing the next reboot (boot prefetch training)<br>
          - Run disk defrag and optimize boot files (Windows 7 only): defrag c: /v /b<br>
          - If using a dynamic virtual disk, use the vendor's utilities to perform a "shrink" operation<br>

    Might wish to update the URL noted above, regarding the GPO setting for disabling the Offline File Service. The new URL is gpsearch.azurewebsites.net/default.aspx
