Patent ID: 8489709

Claim:
A method of managing a file access, in a system which comprises a plurality of host computers, a network, and a plurality of file servers, respectively storing at least one or more files, wherein each of the host computers is connected with a target file server associated with the each of the host computers via the network, and issues a file access request to the target file servers, for access to a target file stored in one of the file servers, comprising the steps of: collecting a load information from the file servers; analyzing the load information, by specifying location of the target file and the target file server; redistributing the target file among the file servers based on the load information; and reallocating connection between the host computers and the target file servers, wherein the target file server redirects the file access request to a file server other than the target file server, if the file server other than the target file server stores the target file, wherein the load information comprises information of the target file server, information of the redirected file server, and transfer size, wherein the transfer size shows the size of inter-node communication between the target file server and the redirected file server, and wherein the target file is redistributed so that the total size of inter-node communication between the target file servers and the redirected file servers is reduced.
