Abstract

Allocating a resource of a storage device to a storage optimization operation. An available resource of the storage device is monitored. Determining an allocation proportion of the resource allocated to the storage optimization operation, based on at least one of historical running information and a predicted value of a performance improvement caused by the storage optimization operation. Allocating the resource of the storage device to the storage optimization operation based on the available resource and the allocation proportion.

Description

technical field [0001] The present invention relates to data storage optimization, and more particularly to a method and system for allocating storage device resources for machine-executed storage optimization operations. Background technique [0002] In the field of data storage, a storage device with a hierarchical storage architecture is often constructed to be used by one or more hosts to store data, so as to achieve a balance between storage cost and storage performance. Specifically, storage devices with different performances and costs may be used to form a hierarchical storage architecture, and the storage devices may be mechanical hard disks (HDDs) with different performances (such as rotation speeds), flash-based solid-state drives (SSDs), and the like. For example, a 15,000-rpm HDD, a 7,200-rpm HDD, and an SSD can be used to construct a three-tier storage architecture. Correspondingly, in order to improve the usage efficiency of the storage device and reduce the ...
