Problems solved by technology

[0008] If the 3T hard disk is damaged, it will take more than 4 hours to complete the data re-consistency, and the reading and writing will be affected during this process.
[0009] The number of replicas is generally an odd number, and split brains are prone to occur during elections, making it impossible to determine the master copy

Embodiment Construction

[0040] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0041] A preferred embodiment is given below:

[0042] For distributed storage, partition fault tolerance is a basic requirement, otherwise it loses its value. Therefore, when designing distributed storage, it is a balance between consistency and availability.

[0043] For most WEB applications, strong consistency is not actually required, so sacrificing consistency for high availability is the direction of most distributed database p...

Abstract

The invention relates to the field of distributed storage, and particularly provides a distributed storage QOS implementation method which comprises the following steps: S01, establishing and acquiring a distributed storage operation performance system; S02, implementing distributed storage QOS (Quality of Service); and S03, implementing distributed storage CAP equalization. Compared with the prior art, on the premise that the hardware medium is determined, the overall performance of distributed storage is improved, the read-write rate can be controlled through conditions such as clients and applications, the use experience and feeling of users are improved, the satisfaction degree of the users is improved, and good popularization value is achieved.

Description

technical field [0001] The invention relates to the field of distributed storage, and specifically provides a method for realizing QoS of distributed storage. Background technique [0002] Distributed storage is a concept proposed relative to centralized storage. It uses a server with a large-capacity hard disk as the storage medium and forms storage through software management for users to use. Distributed storage can provide various access protocols and support storage modes such as block and object. [0003] The basis of distributed storage is to improve the stability of data persistence through partition fault tolerance. For example, in the case of three copies, the theoretical calculation can reach the storage stability of nine nines, and in order to keep this stability available, strong consistency is generally used. Assure. [0004] The so-called multiple copies and strong consistency are based on the principle of data reading and writing in distributed storage. Ge...
