摘要

Distributed storage system having content-based deduplication function and object storing method. The distributed storage system may include a plurality of data nodes and a server coupled with the plurality of data nodes. Each one of the plurality of data nodes may be configured to store at least one object. The server may be configured to perform a deduplication function based on a content-specific index of a target object and content-specific indexes of objects stored in the plurality of data nodes in response to an object storage request from a client, and configured to store the target object in one of the plurality of data nodes based on a result of the deduplication function performed by the server.
