For Increased Data Integrity and Availability
LSI offers a family of MegaRAID® battery backup units for use with our
high-performance MegaRAID storage adapters. These backup units protect the
integrity of the cached data by providing power if there is a server failure or
complete AC power failure. The industry-exclusive MegaRAID transportable battery
backup units (TBBUs) offer an additional layer of fault tolerance by protecting
data in cache during adapter field replacement.

MegaRAID Battery Backup Units (BBU)
Add-on modules that protect against data loss in the event of a server or
power failure by providing emergency power to the cache memory. When power is
restored, the data not yet written to the hard drives can be retrieved from
cache memory.

*The Intelligent Battery Backup Unit for these controllers
need an expansion cable for remote connection. Since server and workstation
chassis vary from vendor to vendor, there is no standard mounting option that
addresses all the desired applications. Therefore, the battery kit contains the
battery and cable, allowing users to customize the location of the battery for
the most flexibility within various environments.
