    According to the mellanox spec sheets the connectx-2 cards Support sr-iov and rdma.
    The cards are so cheap because they are end of life and the support was dropped by dell, hp and others.

    Thanks, that is good to know! I'll start with a couple of the connectx-2 cards then, I don't mind saving money. Now I just need to find an sfp+ card for my qnap tvs-1282, I know qnap re-brands someones cards but their version is crazy expensive.

    thinking about grabbing a few of these. I have intel x540-t2's deployed and I am kicking myself for their lack of RDMA support

    Any difference between this one and the Chelsio T520 or than one being older?
