Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification Overview
The Intel
®
RAID Smart Battery AXXRSBBU7 monitors the voltage level of the DRAM modules
on the RAID controller. If the voltage drops below a predefined 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 an 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. An estimated battery backup retention time is
72 hours (three days).
