I chose to use RAID contollers from CMD Technology Inc. (1-800-426-3832) because they have a line of RAID controllers for which I did not require any special drivers. The controller itself slides into a half-height drive bay and connects to the SCSI bus. It then has multiple drives connected onto it's output SCSI bus (or buses). We used the OS's existing SCSI drivers and configured the OS to believe it had 1 logical SCSI drive, and the fact that the RAID controller was intercepting the SCSI commands and writing the data to different physical drives was entirely transparent to the OS. It works like a charm. Perhaps this solution will work for you as well. Good luck. Dean Neumann TeleLink Technologies Inc. dneumann@telelink.com
