COMMAND PROCESSING METHOD FOR DISK STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a command processing method for a disk storage device by which a deterioration in performance of the entire disk storage device can be prevented by shortening useless rotational latency time and useless access latency time. SOLUTION: The command processing method for the disk storage device is characterized in that: alternate information is referred to upon registration of a command queue, and an alternate address present within the access range of commands is separated before reordering; the address of an alternated area divided in the command is registered by an alternate destination address; and commands are arranged in order of real addresses by executing reordering in the divided state of the command.
