That system is what HP people call a Model 20, 20 for the # disks you
can stick in it.  There was a model 10 and 30 also, the 30 has fibre
channel connections on it, but the 10 and 20's were fast-wide-diff
(20mb/s).  To use that box you'd need a differential controller.  The
disks inside the unit are single ended fast scsi 50-pin though, so you
can put what you want in there as long as the firmware likes it.
