RAID Controllers and Drive Modules
The Xserve RAID system has two RAID controllers, each of which controls the drive modules
on one side of the system. The drive modules are numbered 1 to 7 on the left side of the
system and 8 to 14 on the right side (when viewing the system from the front).
When planning the arrangement of drive modules and RAID levels for your system, it’s useful
to know how the RAID controllers map to the drive modules, as well as how a RAID set
appears on the host system.
The bottom controller controls drives 8–14
The top controller controls drives 1–7
