Abstract: The present invention relates to a file processing method using a data server included in a storage system, such as a Network File System (NFS) or a Distributed File System (DFS). When a file request is received from a client, a file corresponding to the request is loaded. Processing requested by the client is performed on the loaded file. A result file on which the processing has been performed is generated and transmitted to the client. Accordingly, the redundant resources of the data server can be sufficiently used, unnecessary data transmission can be reduced, and the resources of the storage system can be efficiently used.

Abstract: Disclosed herein is a distributed file system using a torus network. The distributed file system includes multiple servers. The location of a master server may be determined to shorten the latency of data input/output. The location of the master server may be determined such that the distance between the master server and a node farthest away from the master server, among nodes, is minimized. When the location of the master server is determined, the characteristics of the torus network and the features of a propagation transmission scheme may be taken into consideration.
