The official answer that you would receive from Cisco, HP, and/or IBM is that you should run consistent firmware across all systems. In addition, they also recommend that you run the same speed of drive at least on a server level - i.e., all drives are 10k or 15k - not mixed and match.


Unofficially, at a previous company I've been at we had 8 CCM clusters one of which was a fully loaded cluster. Over the years, we ended up with mixed firmware and mixed drive speeds and there was no clear indication that it specifically caused any issues.
