CacheVault Flash Cache Protection Module for 9271 and 9266 Series
RAID controller cards temporarily cache data from the host system until it is successfully written to the storage media. While cached, data can be lost if system power fails, jeopardizing the data's permanent integrity. CacheVault flash cache protection modules and battery backup units (BBUs) protect the integrity of cached data by storing cached data in non-volatile flash cache storage or by providing battery power to the controller.
The LSI LSI00297 is the CacheVault Flash Cache Protection Module for the 9271 and 9266 Series.
