I've heard conflicting stories as to whether the controller is truly OS-neutral. We are going to be testing some complete OS-neutral RAID controllers next week; the name escapes me at the moment. Basically, you plug up to 15 Wide drives into one of these, plug it into your existing SCSI card, and voila; you have hardware RAID 5 with hot spares. To your SCSI adapter, it's just one big SCSI device. If the Compaq one works like that as well, we would also give it a shot, but overall we're looking to improve the reliability of the SCSI adapters that do fail in our systems - the standard clone-like machines. With the exception of that Micropolis, we've had nothing but good results with the ProLiants. -- j.
