The versions of CentOS 6 this cluster is running are from 2013 and
2014 so they are looking at 10 year old infiniband. Going from that, I
think the best they can hope for is a Mellanox ConnectX-3 which seems
to have some caveats https://access.redhat.com/solutions/302543. The
ConnectX-4 came out in late 2014 early 2015 so i don't know if its
drivers ever were set to EL-6

I agree with Gordon that you need to plan on upgrading more than just
the backbone network since you are probably looking at significant
downtime to do that AND are in a high risk for security problems.

time to shutdown -h now.
