Need server to support dual GPU's

[NowThatsDamp]

So I have a very specific use scenario. I want to build four servers, each with two cpu's (LGA 1567, LGA 1366 is an option but less preferred) and with two dual slot GPUs each.

The big trick that I'm struggling with is finding a server that has the 8 pin and 6 pin pcie connectors for each of the two GPUs. Everything seems to be cordless.

Does anyone have a recommendation for a server that would suit my needs?

My storage needs are minimal, so don't worry about that.

Those just supply power, so you could add another PSU just for supplying power to the two GPUs, Austin Evans style.

They're going to be 24/7 high demand systems.

You could do it in a way more elegant way though... But yeah it isn't the best but if there is no other option at least there still is this one.

I had to unfortunately split off the molex connectors because they were the only other power connector in my SuperMicro chassis (I have one that doesn't have any PCIe power). I had to get some molex to PCIe 8 pin and six pin for my 980 Ti. I know the PSU is more than capable (920W) so I had no issues. Just a lot of cable mess sadly. You'd need quite a lot of splitters for dual GPU power though.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813182186 these mobos support dual gpu's now you just need case, psu, cpu and storage

May I ask why you want such an outdated and inefficient platform for high demand servers? Why not something newer like LGA2011? The better overall performance per core and better efficiency will save you a lot on the power bill. Plus, better connectivity.

Dell precision r5500. Its built to hold 2 dual slot gpu's and its dual 1366.

 

For 1536, your not going to get a gpu server as if you need the extra cpu of 1536, you don't need gpu's for most uses.

 

Id also look at the newer r720, dl 380 g8(i think it does gpu) and a dell precision r7610 or 7910(these seem to be really cheap for some reason)

Yep sorry. Its for op. 

 

DON"T YOU WANT TO KNOW ABOUT SERVERS THAT HOLD GPU"S!!!! 

 

\s

@NowThatsDamp Question why LGA 1567 if your only going to use two sockets? Also any pricing in mind? There's a large number of GPU optimized systems out there but the pricing varies wildly.

 

Edit:

Also do you want pre-configured servers or are you prepared to build everything yourself (custom rackmount case e.g. Norco)

Most server GPUs use a single power connector so finding one with 4 connectors is likely tricky. Once I have more details from you I'll see what I can dig up.

I wanted to use 1567 because the e7's that come out on that socket had ten cores are really cheap. Upon another night of pondering my issue however, I wouldn't be opposed to doing what @NelizMastr said and moving to an LGA 2011 board. Did the Dell precision @Electronics Wizardy suggested get updated at any point to LGA 2011, with the dual GPU support?I would prefer a barebones server

I'll have to check the manuals to be sure, also some servers you have to buy extra cable kits to support GPUs. My IBM x3500 M4 supports 2 GPUs and doesn't require any extra cable kits, you need the 900W dual PSU though, but you won't find this server on ebay.

 

LGA 2011 should be a much better platform to use, even if it's slightly more expensive.

Dual/Quad socket LGA 2011 Servers that officially support two or more server GPUs

 

Supermicro:

• Superserver 2027GR series (can be found on ebay)
• Superserver 4027GR series ($$$ on ebay)

HP:

• DL380p Gen8, correct riser + cable kit + PSU options required (see page 50 of quick specs), https://www.hpe.com/h20195/v2/GetDocument.aspx?docname=c04128241
• DL580 Gen8, cable kit required (see page 30 of quick specs), will also support 2 GPUs that need 2 power connectors, https://www.hpe.com/h20195/v2/GetPDF.aspx/c04199329.pdf

Dell:

• R720 (not xd), correct riser required. http://www.dell.com/support/manuals/ed/en/edbsdt1/poweredge-r720/720720XDOM-v3/GPU-Card-Installation-Guidelines?guid=GUID-268578E4-B96B-43BA-AC13-58C567CBB670&lang=en-us

Be warned rackmount servers from these companies expect server GPUs which always have the power connectors on the end not the top like almost all consumer GPUs, typically there is no room to use top connectors. If you 100% need to use top connectors the HP DL580 Gen8 and Supermicro 4027GR are the most likely to work, both either not on ebay or costly.

 

Personally I think your best option is to buy a Supermicro rackmount case that has the correct PSU option for GPUs and populate it yourself using the best motherboard deal you can find.
