2.2.2 System Disk Array
The system disk array contains hard disks for the operating system and
metadata (when configured as a SAN). To prevent data loss in case a
hard disk fails, they are normally RAID protected. Furthermore, these
hard disks are protected with a battery backup unit to prevent data loss,
for instance, in case of a power failure.

slot panel connectors The slot panel connectors of the DVS system
provide, for example, the network connections
to connect the system to a SAN. Furthermore,
if applicable, some additional panels may be
present for internal reasons or on customer re-
quest. More details about the slot panel con-
nectors can be found in section “Slot Panel
Connectors” on page 2-13.
power supply The redundant power supply provides the sys-
tem with power. It consists of several indepen-
dent power supply units: Even if one fails the
others will still supply enough power to keep
the system operational. Further information
about the power supply can be found in sec-
tion “Power Supply” on page 2-14.
More information about RAID can be found in section “Intro-
duction to RAID” on page 5-2. The battery backup unit is de-
scribed in section “Battery Backup Unit” on page 2-16.
