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.
