STORAGE SYSTEM, STORAGE CONTROLLER, AND METHOD AND PROGRAM FOR CONTROLLING STORAGE SYSTEM

摘要

A storage controller (3) is provided in a storage system (1) provided with a plurality of disk devices to control storage of data into the disk devices. A coding part (32) codes data, which is to be stored in the disk devices, by use of an erasure correcting code to obtain coded data. A storage/read-out part (33) stores the coded data in the disk devices and fetches the coded data from the disk devices according to an instruction from a personal computer (5). A send-out part sends out the coded data fetched from the disk devices by the storage/read-out part (33) to a storage system (1B) connected with a storage system (1A) through a network (10).
