A method, computer program product, and computing system for receiving a user data page for storing in a storage system. An unaligned hash representation of the received user data page may be generated. The generated unaligned hash representation may be identified within a hash table, thus defining an identified hash representation. A user data page associated with the identified hash representation may be identified, thus defining an identified user data page. A hash offset reference of the identified user data page may be compared with a hash offset reference of the received user data page. A deduplication operation may be performed on the received user data page based upon, at least in part, the comparison of the hash offset reference of the identified user data page with the hash offset reference of the received user data page.

System and method for performing unaligned deduplication

A System, Computer Program Product, and Computer-executable method for managing cache de-staging on a data storage system wherein the data storage system provides a Logical Unit (LU), the System, Computer Program Product, and Computer-executable method including dividing the LU into two or more extents, analyzing each of the two or more extents, creating a cache de-staging policy based on the analysis, and managing cache de-staging of the LU based the cache de-staging policy.
