Abstract:
Provided is a method for managing cache memory to cache data units in at least one storage device. A cache controller is coupled to at least two flash bricks, each comprising a flash memory. Metadata indicates a mapping of the data units to the flash bricks caching the data units, wherein the metadata is used to determine the flash bricks on which the cache controller caches received data units. The metadata is updated to indicate the flash brick having the flash memory on which data units are cached.
