PROBLEM TO BE SOLVED: To provide a distributed storage system having redundancy capable of increasing the efficiency of high load processing while satisfying a fixed performance request standard related to writing/reading when high load processing is periodically executed in a storage system in which data are stored so as to be distributed to a plurality of storage nodes.SOLUTION: A storage node which executes high load processing performs access in a system waiting for no completion in an asynchronous manner with the other storage nodes, and the other storage nodes perform access in a system waiting for completion in a synchronous manner with the other storage nodes. Also, the storage node which executes high load processing stores the hash value of written data, and any of the other storage nodes stores the hash value of the data with the duplicate of the data written in the storage node which executes the high load processing. |
