METHOD FOR STORING DATA USING GLOBALLY DISTRIBUTED STORAGE SYSTEM BY MULTIPLEXING STORAGE IN SYSTEM, PROGRAM AND RECORDING MEDIUM FOR REALIZING THE SAME ON COMPUTER, AND CONTROLLER ON GLOBALLY DISTRIBUTED STORAGE SYSTEM
PURPOSE: A method for storing data using a globally distributed storage system, a program and a recording medium for realizing the same on a computer, and a controller on the globally distributed storage system are provided to enhance security of the data by dividing the data into a plurality of volumes and distributing/storing each volume to each storage, as the storage optimized to a node side is selected. CONSTITUTION: A path management part(504) calculates an evaluation value representing suitability as a target for each distributed storage based on a bandwidth, a communication expense, a physical distance between the mode and the storage. A storage set management part(505) selects the optimal storage set from the distributed storages based on the evaluation value.
