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.
