Abstract: A storage system includes a plurality of storage devices connected together, where the plurality of storage devices include a copy-source storage device having data to be copied and copy-target storage devices capable of receiving the copied data. The copy-source storage device includes a copy-source controller for checking parameters contained in a buffer newly setting command to determine a group of storage devices to be subjected to a newly setting of a buffer and a copy-target storage device in the group and transmitting the parameters to the specified copy-target storage device. The copy-target storage device includes a copy-target controller for performing a buffer newly setting process in the specified copy-target storage device on the basis of the parameters received from the copy-source storage device and notifying the copy-source storage device of a result of the buffer newly setting process.

Abstract: A storage apparatus includes a memory that stores data groups, a rearranging unit that rearranges a transmission group order of the data groups based on each of storage positions in a storage device provided in a copy destination storage apparatus in which the each of data groups is to be stored, and a transmitting unit that transmits the data groups rearranged by the rearranging unit to the copy destination storage apparatus.

Abstract: A storage system to copy data from a copying origin to a copying destination. The storage system includes a storing area creating unit. The storing area creating unit causes a storing unit in a storage to create a status information storing area to have status information stored therein, based on grouping, the grouping being executed on data that is divided into plural pieces, the grouping being executed when the divided data is stored in the storage. The status information of each group is stored in the status information storing area that is created by the storing unit.
