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.
