        It’s simple as of now if u take currently there are 2 technologies

         

        vSGA  – will support 50% H/W and 50 S/W GPU as of now. Need to wait and see  in feature outcomes of Nvidia and ESXi % of H/W GPU utilization may  increase.

        However advantages of K1 and K2 is you can set power state to max

        Kindly  run the following command and check and share the result will it helps  are not currently these is not supported by Quadro but on GRID K1 and K2  it should.

        nvidia-smi -pl 0

         

        I am running it on quadro 4000 I am getting following error

         

        ~ # nvidia-smi -pl 0
        Changing power management limit is not supported for GPU: 0000:05:00.0.
        Treating as warning and moving on.
        Changing power management limit is not supported for GPU: 0000:42:00.0.
        Treating as warning and moving on.
        All done.

         

        There is one more technology vDGA currently not supported by VMware View

        in this technology

        K1 – 4Entry level users

        K2 – 2 High end users

        this is more like assigning 1 GPU for 1 VM

         

        vSGA is memory based sharing. vDGA is GPU based sharing.

          Where did you find that vDGA is currently not supported by VMware View?

            I think the key word here is "supported".  When View was  in beta earlier this year I successfully used a passed through Quadro 4000 with View.  It is currently "unsupported", but I believe there are plans to support this with View at some point in the future.  I have not tried this again with the GA View 5.2 so Im not positive it still works with the GA version.  With the beta version there wasnt any settings specific to view to get it to work.  Just pass the GPU through, switch primary display to the Quadro, and connect with the view client.

              What kind of performance is everybody seeing with this.  We just upgraded to 5.2 over the weekend and installed a Grid K1 into one of our R720s.  There's nothing else running on the server besides my desktop.  I see memory being reserved on the GPU, but dragging windows around is still laggy and full screen video is not smooth.  GPU utilization is about 40%.

               

              For people who have it working, what kind of user experiance are you seeing?  So far I'm very disappointed.

               

              We're using ESX 5.1 Build 1021289 with the 5.2 agent in the VMs.

                The GPU will not help with window dragging and full screen video, its purpouse is to accelerate 3D content like OpenGL and DirectX.

                You would probably get better experience with windows dragging and video by disabling 3D on your pool.

                 

                Have you done any other tweaks to PCoIP etc?

                  For the window issue you may want to try this fix:

                  http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2010359

                   

                  Since I have the McGyver'd GTX 680 into a K2 I can say performance is lacking.  I was expecting it to be able to smoothly run Windows Media Center to a Tera2 terminal (it doesn't).

                   

                  I'm correct in that there is no management software right?

                    I don't believe that Linjo.  If I start playing a flash video from youtube, I see GPU usage go up on the host.  Aero in windows 7 requires directx, I don't see how this would not accelerate that type of application.  In another example, I run the GPUCapsViewer you posted earlier in this thread.  The benchmark for the furry box reports 27-31fps, the resultant display on the zero client or on the software client isn't smooth at all.

                      Also, doing Windows Key + Tab with a hardware GPU VM is much much faster than if you do it without hardware acceleration.  So I can't believe that the GPU is not assisting in windows aero performance.

                        Sure, Windows Aero will be accelerated but just basic window-dragging will not be...

                        My point was that the primary function of vSGA is to accelerate 3D not video or dragging windows, just want to set the right expectations on this technology.

                          So why does windows key+tab still run badly then?  It's basically a glorified Rolodex of flat 3d surfaces accelerated by your gpu.  I'm just wondering at what point do I stop believing all the vmware sales reps who said hardware gpu support would solve these basic user interface issues and now they aren't.

                            I don't know why, in my setup Aero works fine including windows key+tab even when not using any hardware acceleration.

                            Maybe the problem is elsewhere in your setup? Have you gone through the standard PCoIP optimization and the Windows tuning best practises?

                              Hi Tom,

                               

                              Here is the solution for your H/W.

                              Unfortunately I am also using the same H/W

                              Dell R720 performance makes big difference with small settings at BIOS.

                              Unfortunately our Dell R720 is in production I am not in the position to make changes and check it frequently every weekend I do it.

                              I have tried my level best and now it’s better than before.

                               

                              As u have Grid K1 kindly try following command and share me the result

                              ~ # nvidia-smi -pl 0

                               

                              PFA for BIOS setting for Dell R720

                                Linjo , when you say Aero works fine do you mean fine = acceptable or fine = really well same as physical pc .

                                  Do you remember generally what the settings were related to in the BIOS?

                                   

                                  The only thing on this R720 right now is my desktop, when I get to the office today I'll shut it down and check the BIOS settings for anything that seems off.

                                   

                                  Thanks!

                                    Sorry just saw the attachment, I'll check these out on our R720.

                                     

                                    Thanks
