Abstract

Disclosed is a file access service system including at least one client, a plurality of file servers each having a function for limiting amount of use of a respective storage resource, and a switch apparatus inserted between the client and the plurality of file servers. The switch apparatus, based upon a set value of amount of use of a storage resource that has been set in the switch apparatus, sets a set value that limits amount of use of each storage resource in a respective one of the file servers. The switch apparatus surveys amount of use of each storage resource periodically in each of the file servers and, based upon the result of the survey controls the set value of the amount of use of each storage resource in each of the file servers.
