Abstract

The invention discloses a cache page elimination method, which comprises the following steps of: when a target cache page in a memory needs to be eliminated, moving the target cache page to a first bidirectional loop list; if the target cache page is hit by the host within the preset time, removing the target cache page from the first bidirectional loop list; and if the target cache page is not hit by the host within the preset time, moving the cache page in the second two-way loop list to a third two-way loop list, moving the cache page in the first two-way loop list to the second two-way loop list, and releasing the cache page in the third two-way loop list. Through adoption of the method, not only can the hit probability of the host to the cache be improved, but also the resource utilization rate of the memory can be remarkably improved. Correspondingly, the cache page elimination device, the equipment and the medium provided by the invention all have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, device, device and medium for eliminating cache pages. Background technique [0002] Since the writing speed of the memory is much higher than that of the hard disk, the memory caching mechanism is usually used in the SAN (Storage Area Network) to improve the read and write IO (Input / Output, input and output) of the host. speed. [0003] In the prior art, if the target cache page in the memory exceeds a certain period of time, the target cache page is usually removed from the memory and eliminated, and a new cache page is replaced into the memory. However, this mechanism will reduce the host's cache hit probability. At present, there is no more effective solution to this technical problem. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the present invention is to provide a cache page elimination method, device, device and medium, s...
