Abstract
Embodiments of the present disclosure relate to a multi-node storage system and a data deduplication method thereof. The method includes determining a similarity hash value of a super block, wherein the similarity hash value indicates similarity between super blocks The method further includes comparing the similarity hash value of the super block with a feature similarity hash value of a node of the multi-node storage system to determine whether the super block matches the node and, in response to determining that the super block matches the node, allocating the super block to the node.
