I spent many many hours looking into GPU options for the HP DL380p G8. The documentation and part numbers are very confusing. The goal of this post is to save you a ton of time by explaining what each part number is and exactly what you should buy if you want to have GPUs in your DL380p G8. The DL380p G8 can hold a maximum of 2x ~225W GPUs or Xeon 5110P Phis (the only Phi officially supported...it will recognize others, but it will think they are 5110Ps). There should be about 300W available per GPU (225W from cable, 75W from PCI slot), but you might run into cooling issues. The total cost for a dual double wide GPU or Xeon Phi setup (minus the GPUs or Phis) can be as low as $100. See the following google
spreadsheet for everything you need. Make sure you have the dual 1200W PSUs option if you do this. The dual 750W or 500W ones won't be powerful enough.

Installation is fairly straightforward. You remove the old PCI risers, install the GPUs/Phis into the riser cages, and install the new risers. Then plug a cable into the riser and into the GPU, repeat for other GPU. Make sure you don't mix them up. Unlike the original risers, these are slot dependent.
ReplyDeleteI wanted to thank you for this fantastic spare parts summary document. I was going crazy to find the 728543-B21 to be able to install a K2 grid and in the document there is the equivalent code that does the same thing. Because the 728543-B21 is nowhere to be found.
Same! Greatly appreciate the write up. Now I know I'm limited to only one card in the 25SFF version. Thank you!!
