I've spent some quality time on this well Dell in the past 2 weeks. The SAS card is called SAS5i, and the "i" in PERC 5i and SAS5i means "internal". They also have a PERC 5E which has external SAS ports. The "i" cards are typically integrated, mounted up near the array shelf, where the "e" cards go in the pci-e slot. I'm not aware of an option to configure a Dell server through Dell's site with RAID using the SAS5i card. I got a sweet deal on a refurb 2950 without raid, and trying to convert it to raid has been fun. Jerry
