Problems solved by technology

[0003] However, the current cache algorithm cannot effectively handle random write IO, especially in the case of tight cache resources: random write IO will occupy a large amount of cache resources, but the cache resources cannot effectively accelerate the speed of its flushing, and at the same time affect the Use of cache resources by other IOs
Although the processing speed of some random write IOs has been improved in the short term, it may reduce the overall performance of the system
Once this state persists, cache resources will soon be used up, resulting in a significant drop in performance

Abstract

The present invention relates to a cache resource processing method and device and a computer-readable storage medium. The method includes gathering the write cache resource occupancy; judging the state of the write cache resource according to the occupancy of the write cache resource; suppressing random write IO according to the state of the write buffer resource. The invention realizes the purpose of inhibiting random writing IO when the write buffer resource is short, limiting the occupation of the buffer resource and ensuring the overall performance of the system by selecting the elimination algorithm according to the state of the writing cache resources.

Description

technical field [0001] The present invention relates to storage system technology, in particular to a cache resource processing method, device and computer-readable storage medium. Background technique [0002] In the storage system, data reading and writing capabilities are key indicators. In order to improve IO processing capabilities, caching is the only way for data. Many mature algorithms have been produced, and the most classic one is the least recently used LRU (Least Recently Used) algorithm. . [0003] However, the current cache algorithm cannot effectively handle random write IO, especially in the case of tight cache resources: random write IO will occupy a large amount of cache resources, but the cache resources cannot effectively accelerate the speed of its flushing, and at the same time affect the Other IO usage of cache resources. Although the processing speed of some random write IOs has been improved in the short term, it may reduce the overall performance ...
