CLUSTER MEMORY FILE SYSTEM

PROBLEM TO BE SOLVED: To provide a high-speed and large-capacity memory file system allowed to be shared with a cluster system, to improve the throughput of an application program for treating I/O data of especially large capacity and to expand the application field of the memory file system by providing a memory file system of higher availability. SOLUTION: The large-capacity memory file system can be realized by securing respective memory areas from the main storages of a plurality of nodes in the cluster system, connecting these memory areas and constituting one global memory storage. By mirroring the memory areas of the plurality of nodes, high availability capable of continuing an application without interrupting it can be realized even when a node failure or a route failure in communication between nodes is generated.
