Method, device and equipment for synchronously setting cache acceleration and readable medium

Abstract

The invention discloses a method for synchronously setting cache acceleration. The method comprises the following steps: issuing a cache acceleration setting command to a client by a server, in response to the received command, setting pause and processing the command by the client, in response to completion of command processing, adding a success flag bit and feeding back the success flag bit tothe server by the client, receiving the success flag bit and confirming the success flag bit by the server, and canceling the pause by the client in response to receiving the confirmation information.The invention further discloses a device, computer equipment and a readable storage medium. The pause operation is set at the client, the state is transmitted to the server after the client finishesprocessing, the server receives the information of the client to cancel the pause operation, and the whole opening or closing process is finished, so that the previous command is ensured to be processed when the cache opening or closing command is executed each time, so that conflicts are avoided.

Description

technical field [0001] The present invention relates to the technical field of hard disk cache, in particular to a method, device, device and readable medium for synchronously setting cache acceleration. Background technique [0002] Under the Linux system, due to HDD disk performance problems, the flashing speed of cached data is slow. In order to speed up the flushing of cached data, there is an existing method of using SSD disks to speed up the cache. The existing methods for controlling the startup and acceleration of ssd disks mostly use asynchronous processing methods. The asynchronous processing methods show that they have been completed on the server side. In fact, there are threads in the background that continue to perform related actions. Under the condition that the time requirements are not strict, the relevant requirements can be met. , but if you use scripts to perform related opening actions, it may cause problems. For example, in the situation where the acce...

The existing methods for controlling the startup and acceleration of ssd disks mostly use asynchronous processing methods. The asynchronous processing methods show that they have been completed on the server side. In fact, there are threads in the background that continue to perform related actions. Under the condition that the time requirements are not strict, the relevant requirements can be met. , but if you use scripts to perform relevant opening actions, it may cause problems. For example, in the situation where the acceleration is turned on and the acceleration is turned off almost at the same time, if the opening is not successfully executed but the related operations of closing are performed, many problems will be caused.
