RAID Controllers and Intel
®
Integrated Server RAID Modules provide reliability,
high performance, and fault-tolerant disk subsystem management. A complete fault-
tolerant strategy requires protection for all data, including the unwritten cached data in the
RAM cache. If power is lost, the data in RAM is lost. To avoid this data loss, a battery can
be added to supply power to the RAID RAM during an AC power outage or if the AC
power cord is removed.
The Intel
®
RAID Smart Battery AXXRSBBU3 is a small battery pack accessory for the
Intel
®
Integrated Server RAID and the RAID on Motherboard (ROMB) solutions used on
specific Intel
®
Server Systems. The Intel
®
RAID Smart Battery AXXRSBBU3 preserves
the contents of the RAID DIMM in the event of a power failure. Once power is restored,
all of the preserved data in the RAID Cache DIMM is flushed to the RAID drives. The
AXXRSBBU3 circuit ensures that the backup battery is maintained at full charge for
optimal performance when it is activated.
The Intel
®
RAID Smart Battery has a compact package and contains the following
components:
• Battery pack: The Lithium-Ion (Li-Ion) battery pack supplies power to the RAM if
AC power is lost. The pack includes a smart refresh circuit and charger. The refresh
circuit is based on the Texas Instruments bq2060A SBS v1.1-compliant Gas Gauge IC
Software, which is used to monitor and inform the user of RSB activities.
• Plastic battery holder: The holder is designed to fit the following Intel
