Hello,
I am having an issue whilst testing the suitability of VMware vDGA pass through for 3d modelling applications in my industry.
Our test bed is as follows.
Dell T7610 workstation
Dual 8 core Xeon e5 v2s 3.4ghz per core
Three quadro k4000s
10gb Ethernet
Dual 512gb SAS ssds
192gb of memory
We have two k4000s on one CPU PCI bus and the third on the other PCI bus. We also have a fourth low end card for xorg.
The end user setup is a wyse p45 tera 2 zero client connected to a 30" dell display at 2560x1600 resolution. This has a 1gbe base t link to a nexus backbone which links into the workstations 10gbe interface.
On software, we have esxi 5.5, vcenter 5.5, horizon view 5.3.
VM configuration is 4 cores with 64gb memory and an allocated k4000 running windows 7 enterprise with only the nvidia drivers, VMware tools, view agent and our modelling software.
Our standard setup is a 1:1 using a pcoip host card inside a t7610 delivered to a wyse p45 zero client limited to 120000kbps and unlimited frames. We get a seamless experience.
With the VMS however, we get Max 25fps (based on zero client perf data), windows is jittery on the visuals and frankly it's a pretty awful experience.
Here's what I've tried.
1 removed all PCI cards down to just a single k4000
2 attempted lowering the resolution
3 I've enabled the pcoip server as per the guide
4 I've made several registry changes as recommended on this forum
5 I've configures the GPO to allow 90000kbps and 120max fps
6 I've reinstalled nvidia and VMware view drivers
7 I've made the vmx change to pciHole.start and set it at 2048.
Pcoip zero client reports Max throughput at 48000 kbps so I've ruled out bandwidth limitations.
Zero client also reports max fps set at 120 so I've ruled that out.
GPU performance works perfectly over the same network using a 1:1 host card with zero client configuration so ive ruled out that factor.
I don't know any other reg tweaks but would be happy to hear them.
I'm thinking the issue could be esxi compatibility with the main board of the workstation. I'm also thinking I may have missed configured something but cannot think what.
Any advice would be great as were considering investing heavily in this technology very soon if it gives a great user experience.
Thanks
James
