PROBLEM TO BE SOLVED: To suppress a load imposed when reading the data to be read from one of a plurality of servers that store data by mirroring.SOLUTION: Servers 102-A to C store a plurality of data by mirroring in such a way that the stored contents of blocks, into which the hard disks that the servers 102-A to C have are divided by a prescribed data size, are differentiated between the servers 102-A to C. When reading the data to be read from the servers 102-A to C, a storage control device 101 transmits load information indicating the degree of load imposed on reading of the data to be read, to the servers 102-A to C. The servers 102-A to C, having received a transmission request, generate load information on the basis of the storage positions of the hard disks at which the data to be read is stored, and transmits the generated information to the storage control device 101. The storage control device 101 determines, on the basis of the received load information, the server from which the data to be read is read from the servers 102-A to C.SELECTED DRAWING: Figure 1 |
