Method for accelerating performance of computer disk based on disk cache

Abstract

The invention provides a method for accelerating performance of a computer disk based on disk cache. The method comprises the following steps of: obtaining data access frequency information according to the disk, analyzing and processing through a data distribution adjustment unit, correspondingly placing the data with high access frequency into a high performance disk storage space and relatively placing the data with low access frequency into a low performance disk storage space so as to achieve the purposes of improving the access efficiency and reducing the total cost of ownership. A system architecture comprises a data access frequency statistical unit, the data distribution adjustment unit and a release system unit, wherein the data access frequency statistical unit is mainly responsible for counting various data access frequencies; the data distribution adjustment unit, the core of the method, is responsible for placing the data with a large amount of access into a high performance disk and the data with a small amount of access into a low performance disk according to various data access frequencies and feeding back data address change to the release system unit; and the release system unit is responsible for interactive control between a client and the release system unit.

Description

technical field [0001] The invention relates to a computer application technology, in particular to a computer disk performance acceleration method based on high-speed disk cache. Background technique [0002] Currently, there are more and more computer users, and the amount of data access is increasing. From the previous GB to the current TB level. At present, high-performance disks have good performance, but often have small capacity and high price. The low-performance disk has large capacity and low price, but it often cannot meet the performance requirements. [0003] If the customer uses a high-performance disk, although the access efficiency is superior, the cost is high and a huge capital investment is often required if the capacity requirement is met. [0004] If customers use low-performance disks, although the capacity requirements can be met at low cost, the access efficiency will often not be guaranteed and cannot effectively meet customer needs. [0005] In ...
