No. The difference with these cards (and all of the other cards that use an i960 processor) is not in the chips themselves, but in the firmware that runs on them. The part that I'm unsure of (and I'll find out in the next day) is whether the AAC 2120/2200 cards can migrate the on-disk metadata from an ASR array. Having reviewed the firmware, I'm pretty sure that it can, but I want to make sure before I jeoprodize Don's data =-) > > If you're not sure but optimistic, I'd be happy to give it a shot and > report back.

I can't say that I'm overly thrilled with many things that relate to ASR, but this is worse than normal. Scott P.S. My other email address (for the next week) is scott_long@adaptec.com
