I guess the more important part of what I wrote is that " These SDR HCAs are no longer supported" :)

Some testing from an Intel group who had these QLE7140 HCAs revealed to me that they do _not_ work with our recent software stack such as IFS 7.1.1 (which includes OFED 1.5.4.1) .

They were able to get them to work with the QLogic OFED+ 6.0.2 stack. That corresponds to OFED 1.5.2 -- that was the first OFED to include PSM.
I am providing this info as a courtesy, but not making any guarantees that it will work.

The older QLogic and OFED stacks mentioned above were not ported to nor tested with RHEL 5.9, which did not exist at the time. Sorry.

Thanks,
