"Project: Virtual Reality Check" (VRC).

This is a independent research joint venture between our companies Login Consultants and PQR. The primary purpose of VRC is to release multiple whitepapers to provide information about the scalability and best practices of virtualized Terminal Server and Desktop workloads. The first phase of Project VRC on virtualizing Windows XP and 32-bit Windows 2003 Terminal Services on ESX, XenServer and Hyper-v.

The goal of Project VRC is to investigate, validate and give answers to the following questions:

• How does various Microsoft Windows Client OS's scale as a virtual desktop?
• How does a VDI infrastructure scale in comparison (virtualized) Terminal Server?
• Which performance optimization on the host and guest virtualization level can be configured, and what is the impact of these settings on user density?
• With the introduction of the latest hypervisor technologies, can we now recommend running large scale TS/CTX workloads on a virtualization platform?
• How do the two usage scenarios compare, that is Microsoft Terminal Server [TS] only, versus TS plus XenApp?
• How do x86 and x64 TS platforms compare in scalability on bare metal and virtualized environments?
• What is the best way to partition (memory and vCPU) the Virtual Machines the hypervisor host, to achieve the highest possible user density?

All together over 150 test have been carried out. However, project VRC is not finished, and probably never will be. Additional publications are planned about virtualizing x64 workloads and the other (Vista and Windows 7) client OS's. Also, we look forward to evaluate new innovations in the hypervisor, broker and hardware arena.

The whitepapers can be downloaded freely at source
