Can multiple versions of mlnx-ofed exist in the same IB fabric?

Hi, we have installed compute nodes with RHELS6.3 and MLNX_OFED_LINUX-2.0-2.0.5 using an Infiniband network. We intend to upgrade to RHELS6.7 and mlnx-ofed 3.x.

In a rolling upgrade scenario, can we have both versions of OFED co-existing on the same fabric?

thanks, Greg

Hi Greg,

It is recommended to perform the upgrade during a maintenance windows and not in production, because there are a lot of differences between 2.X and 3.X versions and since part of the driver upgrade is a firmware upgrade also.

Best Regards,
