Indeed, the LSI logic controllers that ship with some HP workstations do not provide adequate RAID protection and as such, is recommended that you either install another RAID controller in the machine or use software RAID. The LSI Logic MegaRAID 8888ELP is pretty good, although a bit pricey. I thoroughly dislike HP's own RAID controller offerings - had more problems with them than I care to mention here.
