I have a large server cluster running CentOS 6.4 and CentOS 6.6 using 10GbE. I want to upgrade to Infiniband.
CentOS 6 hasn't received any feature updates since May 2017, so any compatible hardware would have had to be released and supported before that date (possibly substantially before then).
CentOS 6 has been EOL for almost a year, and isn't receiving any security updates. You *really* should upgrade.
