1.16 Hard Disk Drive Storage

The system chassis can house up to two storage disk cages. The
storage subsystem supports "hot pluggable" universal hard disk drives
that can be replaced while the storage backplane is powered and
operating.
You can install six 1-inch universal hard drives in each storage disk cage. See
Chapter 8 for information on replacing hard disk drives.
