<P>PROBLEM TO BE SOLVED: To realize reliable access of executing programs to a non-local block data storage. <P>SOLUTION: A block data storage service reliably stores block data, which may be accessed over multiple networks by programs executed on physical computing systems, in multiple server storage systems. Block data storage volumes that are respectively stored in at least two server block data storage systems are created, and a first copy is automatically switched to a second copy when it becomes unavailable. A user can use the volumes by the multiple executing programs. A group of the multiple server block data storage systems that store the block data volumes can be arranged in a data center, and the programs that use the volumes to be stored can be executed on the physical computing systems in the data center. <P>COPYRIGHT: (C)2012,JPO&INPIT |
