VIRTUAL DECENTRALIZED FILE SERVER SYSTEM

摘要

PROBLEM TO BE SOLVED: To make a client not pay attention to the number of file servers decentralized in a network and the connection states of storage devices. SOLUTION: This virtual decentralized file server system 1 is equipped with servers 10-1 and 10-2 decentralized in the network 3 and a virtual decentralized file system 11 is decentralized and mounted on each of the servers. Modules 110-1 and 110-2 on the servers 10-1 and 10-2 which constitute this system 11 when receiving a file operation request multicast from a client 2 judge whether or not their servers are optimum servers capable of handling the request according to server information holding parts 15-1 and 15-2 holding mapping tables 14-1 and 14-2 between the virtual decentralized file system 11 and all local file systems 13-1 and 13-2 or server information on all the servers, and makes a local file system of a corresponding server perform requested file operation according to the judgement result.
