Abstract
The system and method store data into disk devices without loss of data, even when write requests having time limits are concentrated on a specific disk. When a write request for a given disk device is issued, if it is determined that some of this write request and other access requests having time limits for this disk device would not be executed within the respective time limits, the system writes the data temporarily into another disk device.
