The confusion is actually on Dell's end. They've overloaded the 'PERC' term to mean both software and hardware RAID. You can build out a 1950 or 2950 with an MPT SAS card instead of an MFI SAS-RAID card, but they will still tell you that you are getting 'PERC RAID'. The power of marketeers. Anyways, I _think_ that the 'i' in 'PERC 5i' is the indicator that it is software RAID, and thus just an MPT chip doing its 'integrated mirror' feature. Scott
