INFORMATION PROCESSING SYSTEM AND CONTROL METHOD FOR INFORMATION PROCESSING SYSTEM

摘要

An information processing system includes a first information processing apparatus coupled to a first magnetic-disk-device groups including first magnetic disk devices whose motors rotate, a second information processing apparatus coupled to a second magnetic-disk-device group including one or more second magnetic disk devices whose motors rotate and a plurality of third magnetic disk devices whose motors are in a stop state. A management apparatus which included in the system is configured to manage the first and second information processing apparatuses, wherein, when data is to be written, the management apparatus outputs a write request to any of the plurality of first magnetic disk devices and any of the one or more second magnetic disk devices, and when data is to be read, the management apparatus outputs a read request to any of the plurality of first magnetic disk devices.
