Title:
STORAGE HIERARCHICAL MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/109007
Kind Code:
A1
Abstract:
An application itself or a manager of the application copies data of a high reference frequency from storage to a server or a higher level within the storage, and therefore, if I/O, other than the data that has been copied by the application to the server, becomes disproportionate, there is a possibility that performance will decrease. Therefore, a management computer according to the present invention performs hierarchical management of data stored to any of a plurality of types of memory devices within a storage device in accordance with access conditions for the same. Even with respect to data which are stored in a plurality of types of memory devices and which are data other than that accessed by processing of the application, the data are subject to the hierarchical management in conjunction with the application.
