Abstract
A distributed storage system called StorFS that performs distributed data deduplication is described. In an exemplary embodiment, a storage controller server determines if there is duplicative data in a distributed storage system. In this embodiment, the storage controller server determines if an entity is duplicated in the distributed storage system in line with an incoming input/output operation. The storage controller server determines if the entity is duplicated in the distributed storage system by receiving the entity and looking up the entity in a data deduplication table. If the entity exists in the data deduplication table, the storage controller server updates the metadata for the entity to point to the duplicate entity.
