I don't post official announcement from companies usually but I have to good reasons to post this one : This is a very interesting and useful reading, a must know data you need to have in mind and it's refreshed often enough to stick to the real world environment. Then two of my CTP mates are leading this project with great enthusiasm : Jeroen VanDeKamp and Ruben Spruijt. Amsterdam, 17 January, 2013 - Project Virtual Reality Check (Project VRC) is pleased to announce the release of the long awaited 'Phase V' white paper which provides independent insights in the impact and best practices of various antivirus (AV) solutions on VDI performance. The R&D project ‘Virtual Reality Check’ (VRC) was started in early 2009 by the Dutch IT companies PQR (www.pqr.com) and Login Consultants (www.loginconsultants.com) and focuses on research in the desktop virtualization market. Several white papers were published about the performance and best practices of different hypervisors, application virtualization solutions and Windows Operating Systems in server hosted desktop solutions. This new white paper contains the test results of the VDI performance impact of the antivirus solutions from three leading vendors: McAfee, Microsoft and Symantec. “When VDI is implemented into production, performance is often a serious issue. A performance impact of up to 40 percent is not unusual after antivirus is installed.” said Jeroen van de Kamp, CTO of Login Consultants “While this aspect has been less of an issue with PC’s or laptops, with performance sensitive environments like VDI it means you need to invest in servers and storage. This was the reason for us to investigate, and provide objective data about, the exact impact of antivirus on VDI”. “It is important to highlight the fact that Project VRC does not evaluate the quality of the security features of the different AV products, but only provides information about the impact these solutions have on VDI performance” said Ruben Spruijt, CTO of PQR “By testing and comparing different solutions and configurations we discovered the best practice to perform a pre-scan of the master image before it’s deployed. The effect is huge and therefore highly recommended”. Another key finding published in the white paper is that antivirus off-loading architectures makes a big difference from a storage IO point of view, but not always from a session density point of view. All Project VRC tests are performed with Login VSI (www.loginvsi.com), the industry standard benchmarking tool for VDI. This software tool…

VDI Project – Not only a XenDesktop project (part.1) VDI Project - The framework (part.2) VDI Project - Hypervisor war (part.3) VDI Project - Desktops and applications delivery (part.4) VDI Project - User Environment Manager (part.5) Cool title right ? If you click on it then this title was just perfect :) Within my desktop industrialization and virtualization project, I had of course the first layer to analyze : Hypervizors. What is installed, what can be challenge, why bringing a change to this existing layer ? And which product I should push against the one already present ? This is the announce war, if there is some Hyper-V or Vmware I should try to push XenServer (I'm a Citrix preacher guy) and on any case, I should change everything to show I've been here and mark the path of changes.... Nope I didn't, this is 100% vSphere deployed full packed with a very good team handling the infrastructure and a lot of processes and work-flow already running, so I don't see any advantage for my customer (and for me) to change what's working and in place. Changing an installed hypervizor on a large deployment would mean : Changing / adapting processes Industrialization rebuilding Engineer and administrators teams training Heavy and long migration (V2V..) Lost of focus regarding what bring me first on this "Desktop" project Maybe reduction of administrators / engineer As I mentioned in the part 1 & 2 of this blog, in fact I didn't had to test anything because the choice have already be made. I would have like to make my own benchmark test and comparison but limited time and specific politics in this project were in the game. If you want to go further on this subject then I encourage you to read Project VRC - Phase II version 2.0 white paper full of very interesting information. Now I need to keep in mind this architecture piece I would have to address, I don't know bunch of thing about vmware vSphere, I will use some help on that subject by some other expert. The announce war didn't happen and I'm very disappointed about that, I would have like to make my own test and publish result I got from an extreme VDI benchmark. I will do it, sooner or later !
