Abstract

The present disclosure directs to solutions for performing deduplication by a storage device. In the solutions, according to a duplicate data locality principle, non-duplicate data blocks whose logical addresses are contiguous are stored in contiguous physical addresses in a sequence of the logical addresses, and fingerprints of the non-duplicate data blocks whose logical addresses are contiguous are also stored in contiguous physical addresses in the sequence of the logical addresses, and in addition, a mapping from a logical address, which is of one data block in the non-duplicate data blocks whose logical addresses are contiguous, to an aggregation address is established.
