Red Hat do have documentation on setting up IB too.  This might be a 
good starting point:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-infiniband_and_rdma_related_software_packages

You should also be able to call on Red Hat for support with this as well.

Best of luck!
