Method and device for regulating and controlling memory and medium

Abstract

The invention discloses a method for regulating and controlling a memory. The method comprises the following steps: creating a parent memory pool based on all memories; occupying a memory of a predetermined size from the parent memory pool to create a child memory pool; judging whether the memory size of the sub-memory pool can meet the current requirement of the system or not; in response to thefact that the memory size of the child memory pool cannot meet the current requirement of the system, sending a memory request to the parent memory pool; and the child memory pool receives the new memory allocated by the parent memory pool. The invention further discloses computer equipment and a readable storage medium. According to the method and device for regulating and controlling the memoryand the medium, through cooperative use of the parent memory pool and the child memory pool, dynamic change of the memory is achieved, system memory resources are fully utilized, the response speed todata writing of a user is increased, and the read-write performance of a storage system is improved.

Description

technical field [0001] The present invention relates to the field of storage, more specifically, to a method, device and readable medium for regulating memory. Background technique [0002] A cache is a module in the storage device software system. When the data that the user intends to write to the disk array passes through the cache module, the cache module first caches the data and replies with a storage success response to the user, and then writes the user data into the disk array. In this way, compared with writing user data to the disk array and then responding, it can improve the response speed to the data that the user wants to write to the disk array, and the cache module has read hit and read-ahead functions to improve storage response to the user's read commands. The response speed, cache write data, read hit, and read-ahead functions can all improve the read and write rate performance of the storage device. [0003] The larger the memory occupied by the cache ...

Problems solved by technology

However, there are other software modules in the storage device software system. If the cache module takes up all the system memory or takes up too much memory during initialization, other software modules cannot allocate enough memory, causing other software modules to fail to run; if the cache module Too little memory will lead to poor performance of the storage system, so how to set the system memory occupied by the cache module is an important issue
