摘要： A storage system having a plurality of storages. The each of the storages include a memory and a processor coupled to the memory. The processor executes a process including transmitting an update request for data which is commonly stored in the plurality of storages according to a predetermined transmission order indicating a path to transfer the update request. The process includes updating data when receiving an update request from another storage. The process includes changing the predetermined transmission order to a transmission order in which one or more storages included in the path are excluded according to the number of times the update request for the data is received.

摘要： A storage device is one of a plurality of storage devices storing replicas of data. The storage device includes a memory and a processor coupled to the memory. The processor executes a process includes transmitting an update request to at least one destination storage device through a plurality of paths when the storage device is requested to update the data by a client. The process includes notifying the client that the updating of the data has been completed when having received a response through one of the paths, the response being issued by the destination storage device serving as the terminal point of the path when the destination storage device receives the update request through all the paths having the destination storage device as the terminal point.
