Re: Nvidia Quadro

Could you tell us some more about your setup?

Environment is running on all latest patches and latest build of ESXi 5.1 with VMware View 5.2

1. What OS are you running on the client and virtual desktop?

Client is Dell P25. VM OS windows 7 x64.

1. How is the virtual desktop configures? vCPUs, Memory and vRAM?

VMs are fully cloned and manual pool. 2v CPU, 16 GB RAM and 512MB vRAM.

1. What GPU are you using and what driver-version?

Nvidia Quadro 4000.  Driver version NVD.NVIDIA_bootbank_NVIDIA-VMware_304.76-1OEM.510.0.0.802205-999851.

1. What ESX builds?

ESXi,5.1.0,1021289

1. How did you verify that vSGA is working properly?

By entering following commands and you see the current status as well

1. Do you experince the same if you are accessing the vCenter console?

Yes even on RDP as well. We can see that each GPU is handling 5-6 VMs but there is no such GPU utilization is happening.

1. How do you measure and detect that the performance is changing? Are you using some tool in the desktop?

We can detect performance by open GL tools we are getting 30FPS. But 3D application will take too long to perform certain tasks.

1. How many vm:s are sharing the GPU?

As you can see above 5-6. Max we can allocate per VM is 256. 256 will be s/w GPU and another 256 will be h/w GPU.

1. Could you post an output from the command: "nvidia-smi" from a console session on the host?

                You can find it in 5^th answer
