  • Method for storing data using globally distributed storage system, and program and storage medium for allowing computer to realize the method, and control apparatus in globally distributed storage system
    Publication number: 20040064633
    Abstract: A control device for preparing redundant data, dividing the data into a plurality of volumes, and distributing and storing volumes in a plurality of storage units scattered through a network includes a route management unit and a storage set management unit. The route management unit computes an evaluation value indicating the preferability of a use target on each of the scattered storage unit based on the bandwidth, the communications cost, the physical distance between a node requesting a write and a storage unit. The storage set management unit selects a plurality of storage units as the optimum storage set from among the above mentioned scattered storage units based on the evaluation value.
