Описание
Once a data write is completed, the cache must be able to protect this data in the event of a power loss before the write data is moved to the drives. If external power to the system is interrupted, if the host computer fails, or if the raid controller fails, battery power maintains data in the cache long enough for the user to recover the data and preserve the integrity of business-critical information. Depending on the capacity of the batteries when external power is lost, battery-backed cache is typically capable of retaining the integrity of data in the cache for several days. The batteries used in battery-backed cache are rechargeable, allowing them to maintain full charge even after a power failure. Cached data is protected by not allowing posted-write operations unless the batteries are at an acceptable charge level to back up data for a predetermined duration.
