摘要：
Storage nodes participating in the distributed storage system are divided into groups beforehand. A data replica creation unit operates so that a replica is created on each of the nodes participating in the distributed storage system on a hash ring. A unit that specifies an operating state of the system determines the number of data replicas for each group. The data replica creation unit traverses the hash ring and creates one or more replicas until it is determined that the number of replicas for each group is reached.
