RAID Smart Battery AXXRSBBU7
The battery pack charges automatically and communicates battery status information, such as
voltage, temperature, and current to the host computer system.
During RAID controller operation, a “write back cache” option is available where data is first
written to the RAID controller cache memory and held in memory until the disk is available for
the write to complete. This improves write performance as it is faster to write data to the RAID
adapter’s cache memory than it is to write it directly to a storage device. These write operations
are completed quickly at the software application level. The RAID controller then writes the
cached data to the storage device when it is available to accept the write.
This method of writing data carries a risk. Cached data on the RAID controller can be lost if the
AC power fails before the data is written to the storage device. The Intel
®
RAID Smart Battery
AXXRSBBU7 mitigates this risk by providing battery power to the RAID controller if the AC
power fails.
