Mellanox ConnectX-2 MHRH2A-XSR 10GB

I am looking at some Mellanox ConnectX-2 MHRH2A-XSR 10GB cards one for my unraid server and one for my desktop. These are supported by unraid out of the box? Also If I have 1 in my server 1 in my desktop can I connect them together for faster transfer speeds from my desktop to my server? Then use a 1 GB ethernet to our regular network for other PCs on our network to access the unraid server? 

 

Also what cord will I need to connect the Mellanox ConnectX-2?

 

Thanks

Unraid don't support Infiniband, they can probably be set to Ethernet model but might be best just to buy Ethernet models, those are plug and play, you can use direct attach copper cables for short lengths or use fiber for longer ones.

Thanks any suggestions on cards that are supported?

Great was not sure if being an HP oem it would not work. 

You can also reflash them with the real "Mellanox" firmware so that they appear as real Mellanox card, simply install the Mellanox Firmware Tools and go to the plugin page and read the instructions on how to do that, please be sure to select the right firmware if you want to do that.

Have you tried to switch the mode yet to Ethernet and see if they work in unRAID?

I had one user that switched modes but I don't heard back if it was working.
