Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings. The storage system caching strategy adaptive method includes the following steps:

[0022] (1) Monitor and count the data access requests received by the storage system, and analyze the statistical information of the data access requests to obtain the data access mode of the storage system. The data access mode of the storage system refers to the access characteristics of the data access requests sent by the upper application to the storage system, including the ratio of read requests to write requests for data access, the randomness of data access, and whether there is hot data.

[0023] The statistical function and statistical data records of data access requests can be merged and shared with other functional modules in the storage system, thereby reducing the performance overhead of implementing the request statistical function. At the same time, statistics on acce...

Abstract

The invention particularly relates to a storage system caching strategy self-adaptive method. The storage system caching strategy self-adaptive method includes the steps of: performing statistical analysis on data access requests of a storage system to obtain a data access mode, and automatically selecting a proper caching strategy according to the date access mode. The storage system caching strategy self-adaptive method solves the problems that the single caching strategy of the storage system cannot adapt to complex and fickle business requirements and change of the caching strategy needs to be performed manually, so that the storage system can automatically select the caching strategy best for the current date access mode according to change of the actual date access characters, the cache hit ratio is improved, the caching pollution is reduced, the caching performance overhead is lowered, and thereby the performance of the storage system is promoted.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a storage system cache policy self-adaptation method. Background technique [0002] The hardware that constitutes the computer system is diverse, and the IO access performance is also very different. In order to solve the data transmission between hardware devices with different IO performance, people invented the caching technology, and then formulated a series of caching strategies. The cache improves the hit rate of the cache content by designing well-designed data block, prefetch, sequential prefetch, cache replacement and other algorithms. In the storage system, the main caching strategies include: access time-based strategies, access frequency-based strategies, access time and frequency-based strategies, and so on. The traditional caching strategy mainly includes specifying which data needs to be cached, specifying when to perform a cache swap operation, and ...
