Redundant storage control device, redundant storage control method, and redundant storage control program

摘要

PROBLEM TO BE SOLVED: To provide a redundant storage control device capable of improving the failure resistance of data writing when failures simultaneously occur in a whole device.SOLUTION: The redundant storage control device includes: acceptance means which accepts a first data writing request and a second data writing request from an external device; and scheduling means which generates a first schedule for allowing an external first storage device to execute processing for the first data writing request at a first point of time, and to execute processing for the second data writing request at a second point of time different from the first point of time and a second schedule for allowing an external second storage device to execute processing for the second data writing request at a third point of time different from the second point of time, and to execute processing for the first writing request at a fourth point of time different from the first point of time.
