Suitable server hardware for Mellanox 100GE NICs


Any recommendation regarding the server to use with Connect-X 4 NICs

As I had issues with our current server, I am looking for a specific server configuration that was tested with those cards. I tried an initial configuration unsuccessfully as described in the comment on that link Getting started with ConnectX-4 100Gb/s Adapter for Linux

CalTech are describing their experiments but i cannot find the server machine that they used

100G Ethernet NIC Tests – Caltech SuperComputing

A detailed description of the server hardware that fits with those cards will be more than welcome

Thanks for your help.

When choosing a server for 100G, think muscles

Recent CPU. Enough and fast memory DIMs. X16 pcie gen-3 bus. SRiOV support (in case you go with cirtualisation).

Hi Charif,

As already mentioned, Mellanox ConnectX-4 100G NIC works in any server that has a PCIE Gen3 x 16 slot. Also depending on the applications you plan to run you may need some RAM and CPU to match your requirements.

If you need more slots for other purposes you’ll want to talk to server vendors and integrators. They have system engineers that can advise.

If I were in your shoes, I would go to my server reseller or integrator and ask for assistance.


Do you have a reference for a model tested w/ more than 6 PCI slots ?
