STORAGE CONTROL DEVICE, STORAGE CONTROL PROGRAM AND STORAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To make it possible to suppress reduction in a data fill rate in a buffer set unit in an order guaranty remote copy.SOLUTION: A control unit 4c is configured to: determine a storage destination of copy object data to be controlled by a controller module 1a (a first controller module) on the basis of configuration information 4b; store the copy object data in a transmission buffer 5a (a first transmission buffer) owned by the controller module 1a when the transmission buffer 5a is the storage destination of the copy object data; and store the copy object data in the transmission buffer via a corresponding controller module (a second controller module) when a transmission buffer (a second transmission buffer) different from the transmission buffer 5a is the storage destination of the copy object data.SELECTED DRAWING: Figure 1
