Embodiment Construction

[0025] In order to solve the problem that the hierarchical management method in the prior art cannot flexibly migrate data between online storage and near-line storage, the present invention provides a hierarchical storage method and device. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments . It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] This embodiment provides a hierarchical storage method, figure 1 is a flowchart of a hierarchical storage method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps (step S102-step S106):

[0027] Step S102, based on the data dynamic classification strategy, decide to trigger data migration under different conditions. Specifically, data grading operations are performed based on the dat...

Abstract

Disclosed are a method and device for hierarchical storage. The method comprises: triggering a data migration on the basis of a dynamic data classification policy; determining to-be-migrated data on the basis of interrelation of files; and, determining, on the basis of a migration rate control mechanism, whether or not to perform the data migration of the to-be-migrated data. Also disclosed is a computer storage medium.

Description

technical field [0001] The invention relates to the field of computer storage systems, in particular to a hierarchical storage method and device. Background technique [0002] Hierarchical storage management refers to physical storage devices that are divided into different categories based on price, performance, or other attributes, and data that is dynamically migrated between different types of storage devices based on their access activities or other characteristics. system. Compared with the traditional storage system, the tiered storage system integrates devices with different performance, capacity and price to provide a storage environment with high performance, large capacity and low price. [0003] In a general hierarchical storage system, there are three levels: online storage, near-line storage and offline storage. The online storage uses high-performance disks, such as SSDs and FC disks. Online storage stores a small amount of data with high value and access f...
