Abstract
A multi-level cache comprises a plurality of cache levels, each configured to cache I/O request data pertaining to I/O requests of a different respective type and/or granularity. The multi-level cache may comprise a file-level cache that is configured to cache I/O request data at a file-level of granularity. A file-level cache policy may comprise file selection criteria to distinguish cacheable files from non-cacheable files. The file-level cache may monitor I/O requests within a storage stage, and may service I/O requests from a cache device.
