Disk control method and control apparatus capable of lowering data transfer load of computer

摘要

In a storage disk control appratus (600), a load of a computer (500) caused by transferring data (510) is reduced, and a waiting time until a data transfer operation is commenced is shortened. In the disk control method for controlling a disk appratus (600) including a disk having (502) a plurality of storage regions for storing data therein by way of an external appratus (500) external addresses (511) produced from the external appratus (500) are related to internal addresses (512) indicative of positions of the storage regions the external addresses are converted (501) into the internal addresses related thereto, and the disk (502) is accessed based on the internal addresses. In the disk control appratus (600) for controlling a disk appratus (502) including a disk having a plurality of storage regions used to store therein data, there are provided management means (504) for managing a correspondence relationship between external addresses and internal addresses indicative of positions of the storage regions, and conversion means (501) for converting a preselected external address into the internal address related thereto by the management means (500) and for supplying the converted internal address to the disk. $$
