Non-volatile memory scheduling method, system and device and readable storage medium

Abstract

The invention discloses a nonvolatile memory scheduling method. The method comprises the steps of obtaining a utilization rate of a current memory space; when the utilization rate is smaller than a first threshold value, determining a first to-be-converted space of the memory space, converting the first to-be-converted space into a high-speed storage space, and storing data in traditional storageequipment into the high-speed storage space; and when the utilization rate is greater than a second threshold, determining a second to-be-converted space of the high-speed storage space, storing datastored in the second to-be-converted space into the traditional storage device, and converting the second to-be-converted space into the memory space. According to the method, the nonvolatile memory is scheduled in real time to serve as the proportion of the memory to the data storage, the read-write speed of the data storage is increased while the equipment utilization rate is increased, server jamming caused by too high memory occupation is avoided, and the running speed of the server is guaranteed. The invention furthermore provides a nonvolatile memory scheduling system and device, and a readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of memory scheduling, in particular to a non-volatile memory scheduling method, system, device and readable storage medium. Background technique [0002] Non-volatile memory is a new type of storage medium, which can replace the new generation of memory specification DDR4 as system memory, and can also replace solid-state hard disk or mechanical hard disk as data storage. When used as data storage, the data transfer bandwidth of non-volatile memory is much larger than traditional data storage. [0003] In the prior art, a server system configured with a non-volatile memory device utilizes the non-volatile characteristics of this new type of storage medium to retain memory data even if the server suddenly loses power, thereby improving the recoverability of the application system. However, this technology uses all non-volatile memory devices for memory, and does not consider the possibility of using its high...
