It works in the ProLiant 6000 7000 and 8000 servers and compatible with Wide Ultra2 and Wide-Ultra SCSI hard drives.

These three channels can support up to twenty-one 1 drives on a single controller for the Proliant 8000 (with 18.2GB drives you can add 382.2GB of storage) and can support twelve 1.6 drives or eighteen 1 drives in the Proliant 6000 and 7000.
