The MegaRAID LSIiBBU05 is a battery-backup module that protects the integrity of the cached data on a MegaRAID controller by providing backup power if there is a complete AC power failure or a brief power outage. The LSI MegaRAID battery backup units provide an inexpensive alternative to using an Uninterruptible Power Supply (UPS).
