| Zusammenfassung: | A non-volatile data cache having a cache memory coupled to an external power source and operable to cache data of an external data device such that access requests for the data can be serviced by the cache rather than the external device. A non-volatile data storage device is coupled to the cache memory. An uninterruptible power supply (UPS) is coupled to the cache memory and the non-volatile data storage device so as to maintain the cache memory and the non-volatile storage device in an operational state for a period of time in the event of an interruption in the external power source. |
