Title:
記憶システム
Document Type and Number:
Japanese Patent JP4297706
Kind Code:
B2
Abstract:
A processing system comprises a primary storage system and a plurality of secondary storage systems. The primary storage system is managed by a contents manager that keeps a file system used to make file level I/O accesses to a controller that translates the file access to block I/O to access the magnetic media for the data. The secondary storage systems are available to and accessed by application servers, also using file level I/O. The content manager may change a file or data on the primary storage system and, if so, will also change the file system accordingly. The file system is then made available to the application servers, after the controller transfers changed files to the secondary storage systems using block level I/O.
