This method of writing data carries a risk. Cached data on the RAID controller can be lost if the
AC power fails before it is written to the storage device. The Smart Battery mitigates this risk by
providing battery power to the RAID controller if AC power is lost.
AC power fails before it is written to the storage device. The Smart Battery mitigates this risk by
providing battery power to the RAID controller if AC power is lost.
The Smart Battery monitors the voltage level of the DRAM modules on the RAID controller. If
the voltage drops below a defined level, the Smart Battery switches the memory power source
from the RAID controller to the battery pack. The battery pack provides power for the memory
until the voltage returns to an acceptable level, at which time the Smart Battery circuit board
switches the power source back to the RAID controller. Cached data is then written to the
storage devices with no loss of data. The Smart Battery provides additional fault tolerance when
used with a UPS.

The battery pack cache-memory hold time depends on the size and configuration of the RAID
controller memory. Retention time depends on memory capacity and the number of memory
components on the DIMM to support the capacity. Estimated battery backup retention time is 72
hours.
