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. Call me confused then since when I read the POST stuff coming up on during the BIOS the non-RAID card says Dell SAS 5 versus PERC 5/i which matches what I read on Dell's web site. So Dell SAS for the 9G should be the mpt driver and the Dell PERC for the 9G should be mfi. In theory the 2900/2950/1950/1900 are all the same in this regard since they share the same components but different cases & risers. Doug A.
