Antivirus used here is still our standard McAfee product, not VDI-optimized.<br /><br />2) Yes, CPU is almost always the limiting factor and exhausts first, ultimately dictating the limits of compute scale. You can see here that PVS cache in RAM didn't change the scale equation, even though it did use slightly less CPU, but it all but eliminates the disk IO problem. We didn't go too deep on the higher IO use cases with cache in RAM but this can obviously be considered a poor man's Atlantis ILIO. <br /><br />Thanks for stopping by!Peterhttps://www.blogger.com/profile/07331743507096012047noreply@blogger.comtag:blogger.com,1999:blog-6461067935478170803.post-12715667269701908752014-05-23T21:01:46.086-05:002014-05-23T21:01:46.086-05:00Two questions:

If not, physical box overhead with Win 2012 R2 and 1 AV instance is minimal, when compared to 6 PVS streamed VMs outfitted with 6 AV instances respectively (I am not recommending to go physical though).<br />2. When suggesting PVS cache in RAM to improve scalability of XenApp workloads, do you consider CPU, not the IO, to be the main culprit? After all, you only have 20 cores in a 2 socket box, while there are numerous options to fix storage IO.<br /><br />PS.

I'll add some of the architectural considerations which will hopefully help.

This is super helpful, but there is even less information on sizing for XenApp when GPUs are involved.mongiehttps://www.blogger.com/profile/01528897431449977339noreply@blogger.com
