Mixing HBA's in a SAN

I read that you should not mix HBA's in a SAN.  Obviously this would pertain the vendors, but is there much leeway on the model, or is it always critical that you run the same QLogic models together if you have 2 in one server?

Now what if you have 2 servers?  Is it ok to run 2 Emulex HBA's (same models) on one server, and 2 Qlogics (same model) in another server?  I'm assuming the SAN doesn't care as long as they are matched per server.

Yep - no problem at all.

Again, spot on. Make sure you download and install the EMC-specific drivers, firmware and BIOS from:
