The disk storage units are connected to host computers 1 and to at least two other disk storage units, the disk storage units comprising a data transmission means for executing the processing of transmission of data between them and the other disk storage units, and a connecting adapter 100 retaining management information of data having been subjected to transmission processing by the data transmission means.
