Key points to note on these AXXRSBBU7 Intel Smart Battery Memory Backup Kits:-

The Intel RAID Smart Battery AXXRSBBU7 BBU is an optional accessory for selected RAID controllers. The BBU preserves the contents of the RAID DIMM if the power drops below specifications. It ensures that following power failure or other fatal event, all data on the RAID cache DIMM is flushed to the hard disk drives.

These options monitor the voltage level of the DRAM modules on the RAID controller. If the voltage drops below a predefined level, thiey switche the memory power source from the RAID controller to the battery pack. The battery pack then provide 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.

They also provide additional fault tolerance when used with an UPS.

These Intel® RAID Smart Battery AXXRSBBU7 contains the following components:-

• ::  Board-to-board connector: The Intel® RAID Smart Battery AXXRSBBU7 can connect to the base RAID controller through this connector, as a daughter card to the base RAID controller. 
• ::  20-pin remote battery connector: The Intel® RAID Smart Battery AXXRSBBU7 can remotely connect to the Remote Extender Board (REB) component through this connector. 
• ::  Remote Extender Board (REB): The REB component is used to connect to the base controller through the board-to-board connector, as a daughter card to the base controller, so as to provide a 20-pin inline connector for remote battery installation support. 
• ::  Remote battery connecting cable: A 20-inch 20-pin connector cable is provided to connect the REB card to the battery. 
• The Smart Battery Module which includes the following components:
  •   ::  Smart Battery circuit board: This ensures that the battery is maintained at optimal performance and charge levels. This circuit is based on the Texas Instruments bq2060A SBS v1.1-compliant gas gauge IC. 
  •   ::  Battery pack: The battery pack is mounted on the circuit board. It includes a separate internal circuit logic board and Li-Ion (Lithium Ion) batteries. The logic board provides sensing and management logic to support battery charge, discharge, and monitoring. 
  •   ::  5-pin battery pack connecting cable: The connector is used for communicating between the Smart Refresh circuit board and the battery pack 
• ::  Monitoring / notification software: Monitoring is accomplished through the Intel® RAID BIOS Console 2, Intel® RAID Web Console 2, or Intel® RAID Command Line Utility 2 utilities. The software notifies the user of failures or corrective actions.
