Abstract

A migration policy adjustment method, capacity-change suggestion method and device. The migration policy adjustment method comprises: calculating capacity information of a first storage resource pool of a data storage server cluster within a preset time, wherein, the first storage resource pool is configured to store a data partition having an access popularity value exceeding a preset access popularity value threshold (S102); determining, according to the capacity information, whether a storage capacity of the first storage resource pool has changed (S104); adjusting a migration policy of the data partition of the data storage server cluster when it is determined that the storage capacity has changed (S106). The above solution addresses a problem in the prior art in which a high-performance storage medium is wasted and service accessibility is reduced because of a static manually-configured configuration.

Description

Technical field [0001] The invention relates to the storage field, and in particular to a method and device for adjusting a migration strategy. Background technique [0002] Traditional hierarchical storage is based on the application scenarios where the locality of storage access is prominent, and by introducing a certain proportion of high-performance (read performance) storage media on the basis of the original mass low-performance storage media, the application will be used to access the storage system for a certain period of time. Compare historical statistics with manually preset storage tiering strategies, and increase the content stored on low-level (low-performance) media and whose read access heat exceeds the set rising heat threshold to higher-level (high-performance) storage media Migration; At the same time, the content stored on high-level (high-performance) media and whose read access heat is lower than the set heat drop threshold is downwardly migrated to low-leve...
