centos – Infiniband drivers : OFED or distro included?

I’m setting up a Linux cluster with infiniband network, and I’m quite a newby in infiniband wolrd, any advice is more than welcome !

We are currently using Mellanox OFED drivers, but our infiniband cards are old and not recognized by the latest MOFED drivers. So I’m wondering why not to use distribution shipped drivers (running CentOS7).

What difference will that make to use one or another ? Should I expect any performance decrease ?

thx
