Abstract

The embodiment of the invention provides a method for automatically realizing hierarchical storage and a system for managing the hierarchical storage. A hierarchical storage unit comprises storage layers supporting different access speeds; a storage device comprises a plurality of disk blocks; the method comprises the following steps: performing uninterrupted tracking and statistics on the access frequency of each disk block in a time interval, and periodically and dynamically analyzing hot blocks with the access frequency greater than a first threshold value and cold blocks with the access frequency less than a second threshold; migrating data in the hot blocks to a high-speed storage layer, and migrating data in the cold blocks to a low-speed storage layer.

Description

technical field [0001] The invention relates to data storage technology, in particular to a method for automatically realizing layered storage and a system for managing layered storage. Background technique [0002] Choosing a storage technology often requires a balance between ultra-high capacity, low cost, and low performance, and highly advanced data management features and extremely high performance. With the growth of capacity, manual data migration is too time-consuming, and limited human resources make storage administrators exhausted. Tiered storage becomes a necessary choice architecture, which can integrate capacity, data management capabilities, functions, performance, and price, etc. Factors, provide the most cost-effective storage solution to achieve the above balance. [0003] Tiered storage, when properly designed and implemented, can reduce management costs by deploying tools that can migrate data or applications and respond to their lifecycle needs, and man...
