Our build out of the Open Compute Windmill V3 server utilizes the Mellanox MCX342A XCAN 10GbE, 2-p SFP+ mezzanine card. By default, the Mellanox card is not natively supported by CentOS 6.4.

That being said, I had to download the appropriate driver from Mellanox here. That being said, I also needed quite a few RPM’s to do the driver install, I did:

Even then, I was getting an error:

As it turns out, the symbolic link of /lib/modules/2.6.32-358.el6.x86_64/build to ../../../usr/src/kernels/xxxxxxx was incorrect. I had to do:

within /lib/modules/2.6.32-358.el6.x86_64/

Only then was I able to correctly install the Mellanox driver.
