Abstract: This application relates to distributed storage, and in particular, to a distributed shard storage technology. In a method for storing data shards in a distributed storage system, M data nodes on which to-be-stored data will be stored are determined, N replicas of the to-be-stored data are obtained, and each of the N replicas is sharded into X data shards in a same sharding mode. Then the to-be-stored data is stored on the M storage nodes, that is, N replicas of each of the X data shards are respectively stored on N storage nodes, and a quantity of data shards whose data shard replicas are stored on same N storage nodes is P or P+1, where P is an integer quotient of X divided by CMN.
