We have run into one case where putting SSD's and HDD's in the same card but different enclosures is causing weird batch run time results. IBM is recommending we move the SSD's to a different card. I'm still curious if it will actually "solve" the problem. My fingers are crossed.

Subject: Re: Performance recommendations for pair of 5913s
OK That's what I though. Haven't done it, don't want to try!
Mixing on the same IOA PAIR however using different ports (and thus 5887
drawers) we do all the time with so far no harmful effects.
Thanks!

To be clear you would expect performance to be unpredictable

DID Mix SSDs and Spinnys in the same enclosure (and thus on the same

That is correct, Larry. Remember it is an UNSUPPORTED implementation.
