Abstract
A computer-implemented method for caching content in a cache memory device is disclosed. The method starts with receiving a request for accessing a first data block associated with a first file, and a file manager provides access of the first data block in a persistent storage device of a storage system. The file manager then caches the first data block in a cache memory device including deduplicating the first data block, wherein at least some of data blocks stored in the cache memory device are deduplicated data blocks, and wherein at least one of the data blocks is referenced by different regions of an identical file or different files.
