Abstract
A method implements a cache-policy switching module in a storage system. The storage system includes a cache memory to cache storage data. The cache memory uses a first cache configuration. The cache-policy switching module emulates the caching of the storage data with a plurality of cache configurations. Upon a determination that one of the plurality of cache configurations performs better than the first cache configuration, the cache-policy switching module automatically applies the better performing cache configuration to the cache memory for caching the storage data.
