About the Intel

RAID Smart Battery
Intel
®
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 (RSB) is a small battery pack accessory to the Intel
®
Integrated
Server RAID and the SCSI RAID on Motherboard (ROMB) solutions used on particular Intel
®
Server Platforms. The Smart Battery 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 Smart Battery Circuit ensures that the backup battery is maintained
at a full charge for optimal performance when it is activated. When activated, it provides backup
power to the RAID DIMM for up to 64 hours.
The Intel RAID Smart Battery is a compact package that contains the following components:
Battery pack: The NiMH 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 to monitor and inform the
user of RSB activities is included.
Plastic battery holder: The holder is designed to fit the following Intel

The battery pack fits inside the plastic clamshell, which in turn slides onto connectors in the
server chassis.
Connecting cables: 20-pin cables of multiple lengths are supplied in the kit to support various
server configurations. These cables are connected between the battery pack and a connection
point on the Intel
®
Server System.
