Supermicro Motherboard X11DDW-L/NT, how many number of x16 GPU Cards can i put

[tushar.sharma.9]

Hi everyone,
I want to put two Nvidia P100 x16 GPU cards on Supermicro X11DDW-L/NT motherboard.

I can't get it from the specifications that whether i can connect both GPU at a time?

Plz guide. It's important for me.

That motherboard is for a rack mount server chassis. If you really want a Xeon scalable dual socket motherboard, you should get one of the workstation type boards like the X11DPG-QT or X11DPi-NT.

Yes I want it that way. Its a 2U rack server chassis. The mob clearly shows one x16 slot while the specs read something else.

A 2U chassis would generally require riser cards to rotate the standard cards 90 degrees. I would expect the motherboard slots to be used with risers.

Dear,
that's where my question arises. How many x16 GPUs are supported by this motherboard. https://www.supermicro.com.tw/support/resources/results.cfm

My guess is that there are x16 slots on both risers, but since Supermicro didn't put a link to the risers on the page, I am guessing. Two on the left and one on the right although the right side may be an x8 electrically since the riser slot is only an x16.

Since you are asking these questions, you obviously don't have any physical hardware. The P100 is going to require a lot of airflow from your 2U chassis fans. My experiences with the major suppliers (Dell, HP, SGI) is that not every 2U server is qualified for Tesla cards, many times because of airflow. You are also going to need hefty power supplies, 1500W for a pair of P100.
