Embodiment Construction

[0025] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0026] The working principle of the system hierarchical storage method of the present invention is based on the locality of data access. The hierarchical storage is based on the importance of data, access frequency, retention time, performance and other indicators, and adopts different storage methods to store data in different performance areas. On storage devices, automatic migration of data objects between storage devices is realized through hierarchical storage management. By automatically moving infrequently accessed data to a lower level in the storage hierarchy, freeing higher-cost storage space for more frequently accessed data, better cost performance can be obtained. In this way, on the one hand, the space occupied by non-important data on the first-level local disk can be greatly reduced, and the storage performance of the entire system can also...

Abstract

The invention provides a grading storage method for a system. According to the importance, the visiting frequency, the retention time and the performance index of data, the data is stored in storage devices with different performances by adopting different storage modes, so as to realize automatic migration of data objects among the storage devices; and the data which is not visited frequently is automatically transferred to lower layers in storage layers, so that storage space with higher cost can be released for the data with higher visiting frequency, so that better cost performance is obtained, further, the space occupied by the non-important data in primary local disks can be greatly reduced, and the storage performance of the whole system is quickened.

Description

[0001] technical field [0002] The invention relates to the technical field of computer storage, in particular to a system hierarchical storage method. Background technique [0003] In today's IT management, data storage challenges are often capacity requirements and performance requirements. Faced with the endlessly growing data volume and ever-larger files, it has become more and more difficult to access, store and manage these data and files, and the management and maintenance costs are also getting higher and higher. To sum up, the main problems faced by enterprises in data storage are: [0004] (1) A large amount of historical data seriously affects system performance, and takes up part of the storage space, and the utilization rate of storage devices is low; [0005] (2) There is a lack of flexible and effective management of the data activity cycle, and the data cannot be flexibly allocated to a reasonable storage space. [0006] In fact, for most enterprises, dat...
