Method for using memory pool resource and related device

Abstract

The application discloses a method for using memory pool resources, including: receiving an IO task corresponding to a disk array; assigning memory nodes of the lock-free memory pool to the IO task based on the memory resource list of the lock-free memory pool corresponding to the disk array; The lock memory pool corresponds to the disk array one by one; memory nodes are used to process IO tasks. By classifying the memory nodes corresponding to the lock-free memory pool corresponding to the disk array, there is no need to judge whether the memory resource has a lock, and the lock-free operation is realized, which greatly reduces the complexity of using the memory pool and reduces memory leaks, etc. Errors that are prone to occur improve the robustness of the system, maintain the stability of memory resource usage, avoid lock judgment, and improve the efficiency of memory pool operations. The application also discloses a device for using memory pool resources, a server, and a computer-readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method for using memory pool resources, a device for using memory pool resources, a server, and a computer-readable storage medium. Background technique [0002] With the continuous development of information technology, more and more data storage technologies have appeared. Among them, redundant array of independent disks (RAID, redundant array of independent disks) is a method of storing the same data in different places of multiple hard disks. By placing data on multiple hard drives, I / O operations can overlap in a balanced manner, improving performance. Because multiple hard drives increase the mean time between failures, storing redundant data also increases fault tolerance. [0003] In the related art, the disk array of the storage system is divided according to stripes, and the disk array stripes are further divided according to the stripes of each disk...

AI Technical Summary

Problems solved by technology

Due to the existence of the lock, if other tasks hold the lock during memory allocation, the current IO task must obtain the lock and wait for the memory pool operation, which will lead to a decrease in IO performance.

This makes the operation of the memory pool more complicated

Complex and inefficient memory operations not only affect the performance of the storage system, but also easily cause problems such as memory leaks, which affect the stability of the storage system
