Jeroen van de Kamp and I are proud to finally announce the official launch of 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 compares the performance of virtualizing Windows XP and 32-bit Windows 2003 Terminal Services on ESX, XenServer, Hyper-v, and bare-metal hardware.

The four resulting white papers can be downloaded for free from www.virtualrealitycheck.net. (free registration required)
The goal of Project VRC is to investigate, validate, and find answers to the following questions:
- How do various Microsoft Windows Client OSes scale when used for virtual desktops?
- How does a VDI infrastructure scale in comparison to (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 Terminal Server or Citrix workloads on a virtualization platform?
- What is the performance impact of adding Citrix XenApp to Terminal Server?
- How do x86 (32-bit) 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 and the hypervisor host to achieve the highest possible user density?
All together, we've carried out over 150 tests! That said, 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 OSes. We're also looking forward to evaluating new innovations in the hypervisor (ESX v4.0, XenServer 5.1, Hyper-V 2.0, etc. ) and hardware arenas.
