Hello,

Please can someone help.

I have a large server cluster running CentOS 6.4 and CentOS 6.6 using 10GbE.

I want to upgrade to Infiniband.

What Mellanox ConnectX VPI is supported natively on these OS’s?

What Mellanox ConnectX VPI is supported using an additional device driver on these OS’s?

  • 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.

  • 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.
