GPU support

Jump to solution

Hi,

I would like to know which of your PowerEdge servers provide PCIe slots for GPUs. I would like know some more details about it as well, i.e. how many slots, how many links, how many GPUs can be plug in, are there any limitations in size or model of GPUs?

Thanks,

Miro

RE: GPU support

Jump to solution

Dell PE servers like the Tx30's series towers, only supports compute cards when configured with the GPU Installation Kit and the gruntier PSU's at the time of placing your order. In this way, the server has the required GPU auxilary power connectors required by many compute cards that Dell certifies (along with other mechanical bits to presumably hold the cards safely).

However, it must be noted that Dell does not support graphics functions via PCIe graphics cards like the Quadro P4000 you mentioned. Dell only supports compute cards intended to provide processing grunt - not graphics emoticon.Huh?.title

Obviously that does not mean PCIe graphics features will not work in this server, only that Dell will not support such configurations if you have issues. In such cases where you have issues with graphics, or use of non certified cards, you'd be on your own.

Just be warned that should you install a graphics card into a PE server and it provides your graphics function, rather than offloading compute tasks, some management features may not be accessible (since they are provided to the DRAC by the integrated graphics which would be disabled ).

As a side note, the PE server i have looked at is teh T630 which is a 2 socket tower server that allows up to 4 GPU compute cards to be installed but dependant on a number of condiitions/configurations of the server itself. Other PE servers modles may differ as to the number of suppoted compute cards.

I've not seen any specific Dell doc that state which servers support which compute cards and how many they actually can support, so unless others know and can share you'll have to do lots of reading emoticon.Confused.title

Finally, it must also be noted that the GPU Installation Kit is not a self installed kit that one can 'order' with the hope of 'upgrading' a server post sale. As such it's wrong to call it a kit which is why i hate it being called that, it should be called GPU Installation Option' within the Dell PE custom configuration web page! So don't expect you can buy a server and then later upgrade it with a simple kit you can buy.

Good luck with your endevour emoticon.Wink.title

Stuhlo,

You can find most of your answers within the tabs found here. Such as system compatibility, as well as supported models of GPU's.

Let me know if this helps.

Provided link contains only information about supported GPUs but I would like know which Dell servers support these GPUs.

Anyway, my second question would be whether it is possible to equip your servers with other GPU models. Specifically Nvidia Quadro P4000.

Thanks.

Similar info as I received from a Dell Tech. We can try and stick anything in there we want, but Dell won't support it if anything goes wrong.

But, we're not trying to do compute stuff, we just need better gfx for stuff running on VMs. For example, our own software includes a 3D Fly-Through module that uses OpenGL. It won't run with only the integrated Matrox gfx in our new R7425s.

Dell says "You should have ordered the chassis that supports GPUs", but then tells me that chassis didn't even exist as an option when we bought them (which I find suspicious, as pre-sale another person at Dell sent me a list of supported GPUs and related info.).

Would our stuff run if I passed the GPU through to the VM? Can I do that with more than one VM at a time?

Yeah, it's very disappointing from Dell, to say the least... It's for everything like this, including drive trays: you should have bought them at the initial configuration (with drives, minimum $600 for a 120GB SSD!!!!). And with the newer systems, such as our R7425, not only is it "use at your own risk, you should have purchased the one we offered at a 600% markup", but on top of it, you get punished acoustically: all the fans kick in at 100% permanently. Makes you feel good about being a customer 🙂

If you look at the bottom of this https://www.dell.com/learn/us/en/04/campaigns/poweredge-gpu the P4000 is indeed supported. But that must be the "order ahead, $4,000 version one from Dell" 🙂

Regarding Nvidia Quadro cards not being options for PowerEdge servers, Dell sells the Precision 7920 Rack workstation which is a rebadged PowerEdge R740 with GPU kit :

The current video card options for the Precision R7920 Rack  are:

  • No Graphics option
  • Nvidia Quadro RTX6000, 24GB, 4DP, VirtualLink
  • Nvidia Quadro RTX5000, 16GB, 4DP, VirtualLink
  • Nvidia Quadro GV100, 32GB, 4 DP
  • Nvidia Quadro P6000 24GB, 4 DP, DL-DVI-D
  • Nvidia Quadro P5000 16GB, 4 DP, DL-DVI-D
  • Nvidia Quadro P4000 8GB, 4 DP
  • Nvidia Quadro P2000 5GB, 4 DP
  • Nvidia Quadro P620, 2GB, 4 mDP to DP adapter
  • Nvidia Quadro P400, 2GB, 3 mDP to DP adapter
  • Radeon Pro WX 4100, 4GB, 4 mDP to DP adapter
  • Radeon Pro WX 4100, 4GB Low Profile, 4 mDP to DP adapter
  • Radeon Pro WX 5100, 8GB, 4 DP
  • Radeon Pro WX 7100, 8GB, 4 mDP
  • Dual NVIDIA Quadro P4000 8GB, 4 DP
  • Dual NVIDIA Quadro P2000 5GB, 4 DP
  • Dual NVIDIA Quadro P620, 2GB, 4 mDP, 8 mDP to DP adapter
  • Dual NVIDIA Quadro P400, 2GB, 3 mDP, 6 mDP to DP adapter
  • Dual Radeon Pro WX 4100, 4GB, 4 mDP, 8 mDP to DP adapter
  • Dual Radeon Pro WX 5100, 8GB, 4 DP
  • Dual Radeon Pro WX 7100, 8GB 4 DP
  • Quad AMD Radeon Pro WX 7100, 8GB 4 mDP

The Precision R7920 is definitely based on the PowerEdge R740. Earlier versions of the BIOS post would only mention R740 and not R7920, Some of the bundled manuals only mention R740 and not R7920.
