Abstract

PURPOSE:To effectively use a secondary storage device and to improve system performance by providing a coefficient showing throughput to the secondary storage device. CONSTITUTION:On a main storage device 1, five blocks 11-15 composed of respectively 10 pages are equipped, and assigned to respective secondary storage devices 61-64. First records 501-531 is a coefficient to show the throughput of the secondary storage devices 61-64 and recorded so that the value having the higher throughput can be made smaller. The number of the times of the access is counted and recorded to second records 502-532 with an access frequency measuring means 3 to the above-mentioned secondary storage devices 61-64. Based on the contents of first second records, a load degree measuring means 41 measures the load degree of the secondary storage devices 61-64 and records it to third records 503-533. Thus, with use of a load degree comparing means 8, it is compared to which secondary storage devices 61-64, the blocks 11-15 are assigned, and the secondary storage device having the lowest load degree is selected.
