2.3.2 System Disk Array
The system disk array contains hard disks for the operating system and
metadata. To prevent data loss in case a hard disk fails, they are normal-
ly 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.
Figure 2-12: System disk array
The hard disks of the array are connected to the system with the help
of disk carriers which make the removal of a hard disk easy, for exam-
ple, in the event of a failure. The system disk array is equipped with the
same type of disk carriers as used in the hard disk array of the Spycer-
Box Flex (see section “Hard Disk Array” on page 2-7).
slot panel connectors The slot panel connectors of the R&S DVS sys-
tem provide, for example, the network con-
nections to connect the system to a SAN.
Furthermore, if applicable, some additional
panels may be present for internal reasons or
on customer request. More details about the
slot panel connectors can be found in section
“Slot Panel Connectors” on page 2-16.
More information about RAID can be found in section “Introduction to
RAID” on page 5-2. The battery backup unit is described in section “Bat-
tery Backup Unit” on page 2-19.
