Simple question: Is it possible to use a 8Gb/s Fiber HBA card with a 4Gb/s system? Is there some technical documentation about that?

Should you mean: Can I connect with a 8Gb/s HBA to a 4Gb/s device/FC switch, then the answer is yes, without a problem, and also to a 2Gb/s device etc. It's basically the same as with ethernet: You can connect a GB ethernet card to a 10 Mbit hub if you like.

What kind of documentation are you looking for?

Hi Sven! Thanks for the fast answer. It's actually enough. I was just looking for a document saying what you just wrote... But thinking technically, it shouldn't be a problem. – waszkiewicz Dec 6 '10 at 12:53
