2.3 Battery Backup Unit
To prevent data loss especially for the metadata when the DVS system
is configured as a SAN, the hard disks of the system disk array (see sec-
tion “System Disk Array” on page 2-10) are protected by a battery
backup unit. If the system’s operation gets interrupted, for example, in
case of a power failure, it will provide power to the cache of the con-
nected RAID controller, so that buffered data will not get lost. Once the
operation of the system is restored, the cached data will be written to
the hard disks.
The battery backup unit is located inside the casing of the DVS system:

The battery backup unit is a rechargeable battery that will be charged
automatically when the system is turned on.
