Abstract

The invention provides a migration strategy adjustment method as well as a capacity change suggestion method and a migration strategy adjustment device. The migration strategy adjustment method comprises the following steps: counting the capacity information of a first storage resource pool on a data storage server cluster within a preset time period, wherein the first storage resource pool is used for storing a data fragment with an access hotness value exceeding a preset access hotness threshold value; judging whether the storage capacity of the first storage resource pool is changed according to the capacity information; and under a condition that the storage capacity is changed, adjusting a migration strategy for the data segment of the data storage server cluster. According to the migration strategy adjustment method, the problem of waste of high-performance storage media or reduction of the access performance of service due to manual static setting of the migration strategy is solved; and the utilization rate of the high-performance storage media can be increased, and the access performance of the service is improved.

Description

technical field [0001] The present invention relates to the field of storage, in particular to a method for adjusting a migration policy, a method and a device for suggesting capacity changes. Background technique [0002] Traditional tiered storage is based on the application scenario where the locality of storage access is prominent, by introducing a certain space ratio of high-performance (read performance) storage media on the basis of the original massive low-performance storage media, the content access to the storage system for a certain period of time will be applied Compare the historical statistical information with the manually preset storage classification strategy, and upgrade the content stored on the low-level (low-performance) medium and whose read access heat exceeds the set rising temperature threshold to the high-level (high-performance) storage medium Simultaneously, carry out descending migration to the low-level (low-performance) storage medium for the ...
