METHOD OF RECONFIGURING NAS UNDER GNS
First Claim
1. A file management method for a computer system having:
- one first server accessed by a client computer;
a plurality of second servers coupled to the first server via a network; and
a plurality of storage subsystems coupled to the second servers, the file management method comprising;
providing, by the second server, as at least one file, data stored in the storage subsystem;
executing, by the second server, at least one first program which performs processing related to a file group, the file group including the at least one file;
integrating, by the first server, directory structures that are unique to the respective second servers to provide a directory structure that is unique throughout the computer system to the client computer;
obtaining, by the first server, from the second server, a utilization state of the first program executed by the second server;
judging, by the first server, from the obtained first program utilization state, whether or not migration of the file group is necessary; and
instructing, by the first server, the second server to migrate the file group in a case where it is judged that the file group needs to migrate.

Abstract
Provided is a file management method for a computer system having: one first server; a plurality of second servers; and a plurality of storage subsystems, the file management method including: providing, by the second server, as at least one file, data stored in the storage subsystem; executing, by the second server, at least one first program; obtaining, by the first server, from the second server, a utilization state of the first program executed by the second server; judging, by the first server, from the obtained first program utilization state, whether or not migration of the file group is necessary; and instructing, by the first server, the second servers to migrate the file group in a case where it is judged that the file group needs to migrate. Accordingly, programs stored in NAS constituting GNS can be used efficiently.
