Abstract
The present disclosure is related to methods, systems, and machine-readable media for supporting deduplication in object storage using subset hashes. A plurality of hashes of a plurality of blocks of a plurality of log segments can be received from a software defined data center, wherein each block corresponds to a respective logical address. Each of the plurality of logical addresses can be associated with a respective sequentially-allocated chunk identifier in a logical map. A subset hash comprising a hash of a subset of the plurality of blocks can be determined that corresponds to a contiguous range of the plurality of logical addresses. A search of a hash map for the subset hash can be performed to determine if the subset hash is a duplicate. The subset of the plurality of blocks can be deduplicated responsive to a determination that the subset hash is a duplicate.
