WebBIOS manages Physical Drive by three numbers (Connector number:Enclosure number:Slot

Connector number is always shown as "()" because it is not supported with this server. The
Enclosure numbers are represented by a number beginning with 1, and the Slot numbers are
represented by a number beginning with 0.
Universal RAID Utility manages Physical Device by a number beginning with 1 and ID, Enclosure
number, and Slot number. The numbers of physical devices connected to the controller are sorted in

Note that the slot numbers shown in Physical Drives
box of WebBIOS are represented by a number beginning with 0, but
those in Universal RAID Utility are represented by a number beginning
with 1.
