The first of this year, we launched our first VDI deployment in our library environment. I started noticing very quickly that thin clients weren’t able to login at after a VDA had 11 sessions. RDP also would not work to that same VDA.
Long story short, after talking with citrix support and doing some troubleshooting of my own, if I remove the K2 card from being used by the VM (pass-through, not vGPU), there is no 11-user limit per VDA. We have two K2 cards per host, so four pass-through GPUs available per 2U server. With the GPU pass-through available, any thin client or fat client that tries to connect in to that Delivery Group basically just kicks them out with no error message of any kind.
I noticed in another thread the following statement:
Probably the first and the last officially supported drivers for win2016 and GRID K* are R367 U4/U5 (369.26/369.49)
I sincerely hope that is not the case, or we just wasted 10’s of thousands of dollars buying twelve K2 cards that are not going to be usable at least in the context of pass-through for our 2016 RDSH VMs. Moving forward, we know we’ll have to buy the M10 cards since the K2’s are no longer purchasable.
We are doing pass-through because we don’t have a high enough vSphere license for that. Would vGPU profiles being assigned to the XenApp much like the pass-through card fix the 11-user problem?
I’m going to bring up a 2012 R2 based XenApp with a pass-through GPU to test with.
Any assistance would be greatly appreciated!
