Abstract

The invention discloses a hierarchical storage method and device. Among them, the method includes: based on the data dynamic classification strategy, determining the migration of data triggered under different conditions; based on the file association rule mining technology, the files are related to each other; among them, the mutually related files are used for automatic prefetching; based on the migration rate control mechanism , Maximize the data migration speed. Through the present invention, based on the data dynamic classification strategy, the migration of triggered data is determined under different conditions; based on the file association rule mining technology, the files are associated with each other; among them, the interconnected files are used for automatic prefetching; based on the migration rate control mechanism, the maximum the speed of data migration. It solves the problem in related technologies that the hierarchical management method cannot flexibly migrate data between online storage and near-line storage, so that it can more flexibly control the trigger of migration, and can flexibly configure hierarchical management policies between online storage and near-line storage. Flexible data migration.

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...
