12.1 Overview of the HDD
This section provides an overview of the HDD and shows its mounting locations.
HDDs are mounted in the four HDD slots in an IOU to expand the storage capacity
of the system. In each HDD slot, a 2.5-inch SAS interface HDD can be mounted. A
filler panel may be mounted in an HDD slot. Active maintenance can be performed
on an HDD.
