Abstract

The embodiment of the invention provides a method for processing data blocks, and data block storage equipment and a data block storage system. The method comprises the following steps of: acquiring an access frequency of each data block stored in the data block storage equipment at the present within a predetermined time interval; moving the data blocks according with a preset condition to the first data block storage equipment, wherein the preset condition is that: the access frequency is less than a first preset threshold value, and the first data block storage equipment is the next data block storage equipment of the data block storage equipment at the present; and/or, the present condition is that: the access frequency is greater than a second preset threshold value, and the first data block storage equipment is the former data block storage equipment of the data block storage equipment at the present; and establishing a mapping relation table for realizing access of the moved data blocks, wherein the mapping relation table comprises a mapping relation between a logic unit address of the moved data block in the data block storage equipment at the present and a logic unit address of the moved data block in the first data block storage equipment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular, to a data block processing method, a data block storage device, and a system. Background technique [0002] Usually, storage devices generally include tape libraries, disks, or disk arrays. In order to improve the efficiency of data storage, the existing data storage system adopts the idea of ​​hierarchical storage, and stores the data in different performance storage devices in the data storage system according to the access frequency, access time, capacity and other indicators of the data to be stored. To achieve automatic migration of data objects between storage devices at all levels through hierarchical storage management. Generally, storage devices at all levels are arranged in order of increasing capacity and decreasing performance. The first-level storage device is used to store data with high access frequency; the first-level storage...
