Embodiment 1

[0125] In the following embodiments, the present invention will be described in conjunction with an example in which the present invention is applied to a virtualized file system that virtualizes a plurality of file systems using a switch and provides file access services to clients as a single file system. figure 2 It is a diagram showing the configuration of a network file system as a client-server remote file system in which a switch according to an embodiment of the present invention is installed. refer to figure 2 , in the network file system, at least one client 1 , at least one server 3 and a switch 100 are connected to the network 2 . The server 3 is equipped with: a file system layer 4, which is composed of software that manages data such as files accessed through the file access service; A file server that provides file access services. In this embodiment, the switch 100 is newly added with a function of performing quota management on a plurality of servers 3 .

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.

Description

technical field [0001] The present invention relates to a switch device logically configured between a client and a file server, and in particular to a device, system, method and computer program for implementing quota management, which are suitable for using multiple file systems as seen from the client A system that virtualizes a file system to provide file access services. Background technique [0002] NFS (Network File System: Network File System) / CIFS (Common Internet File System: Common Internet File System) is used as a protocol, and NAS (NetworkAttached Storage: network attached storage), etc. In network storage systems such as NAS, remote clients are provided with file access services for storing and reading data from storage managed by themselves. [0003] In the conventional network storage system, there is no standard form (mechanism) for cooperating between devices such as file servers and NAS devices so that they operate as a single device, so services provid...
