This 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, this Smart Battery switches the memory power source from the RAID controller to the battery pack. This 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. This Smart Battery provides additional fault tolerance when used with an UPS.
