Method of processing files in storage system and data server using the method

摘要

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.

1. A file processing method through a data server of a storage system, comprising:
receiving a file request from a client; loading a file corresponding to the file request; performing processing requested by the client on the loaded file, the performing of the processing includes:
comparing a size of the result file to be generated after the processing requested by the client is performed on the loaded file with a size of the loaded file andperforming the processing requested by the client on the loaded file if, as a result of the comparison, it is determined that the size of the result file will be smaller than the size of the loaded file; generating a result file on which the processing has been performed; and sending the generated result file to the client.
