COMPUTER SYSTEM AND STORAGE CAPACITY EXTENSION METHOD
First Claim
1. A computer system with a local storage system and an external storage service connected via a wide area network,wherein the local storage system includes:
- a user terminal;
an NAS for providing a storage area to the user terminal; and
an information processing unit for providing the user terminal with the storage area in the NAS by integrating the NAS and the external storage service and thereby configuring a single virtual NAS; and
wherein the information processing unit includes;
a first module for analyzing a file access request from the user terminal and obtaining a path to an access target file;
a second module for judging whether access to the access target file should be permitted or not;
a third module for configuring a single virtual directory and managing the path to the file based on the directory; and
a fourth module for migrating the file to the external storage service based on attribute information about the file.

Abstract
Provided is a computer system configured so that security compliance problems can be avoided and an access control model which can be uniquely customized can be implemented by extending the storage capacity to an external storage service by means of integrated management of an existing NAS(s) and the external storage service, and controlling the optimum data placement according to the confidentiality and importance level of data.
In a computer system according to this invention, a local storage system includes an extended server for integrating a NAS(s) existing in the local storage system with an external storage service and thereby providing a client with a storage area as a single virtual NAS.
