摘要：
An information storage device stores data evenly in each of a plurality of external information-storage devices even if the number of external information-storage devices provided in the information storage system is changed. A division processing unit divides the information to be stored in the information storage devices and distributes the divided information to the information storage devices. A division control unit controls the division processing unit so as to divide the information in accordance with a number of the information storage devices. When the number of the information storage devices is changed, the division control unit controls the division processing unit so that the information stored in the information storage devices is divided by a dividing method suitable for the number of the information storage devices after being changed.
