Description

A cluster storage system expansion method based on the same expansion module

technical field

The present invention relates to a cluster storage system, in particular to a cluster storage system expansion method based on the same expansion module.

Background technique

At present, expansion in general, disorderly or random expansion of performance modules or capacity modules, leads to a mismatch between system performance and capacity, and cannot achieve a good balance, resulting in complex system tuning and unable to obtain balanced performance.

Contents of the invention

The purpose of the present invention is to provide a cluster storage system expansion method based on the same expansion module.

The purpose of the present invention is achieved in the following manner, the system includes: an expansion module, wherein the expansion module is composed of a performance module and a capacity module, wherein:

Performance module: used to improve the performance of the cluster storage system, including bandwidth or IOPS, which is hardware like a gateway or controller, and the performance of the system can be improved by adding such devices;

Capacity module: used to increase the capacity of the system. With the increase of system data, it is often necessary to expand the capacity of the system to store more data. The capacity module is a hard disk or JBOD hardware device, which is used to expand the capacity of the system to create Larger storage space, save more data;

The expansion module is composed of a performance module and a capacity module. According to different cluster storage applications, determine a reasonable ratio between performance and capacity, bind the performance module and capacity module together according to this ratio, and keep this ratio unchanged to become a Expansion module, the same expansion module is expanded for each expansion to ensure the performance and capacity balance of the entire system;

The beneficial effect of the present invention is: through the customized expansion module, the balance of capacity and performance is maintained, thereby ensuring the balance of performance and capacity of the whole system. At the same time, it is also convenient for fault diagnosis and performance estimation of the system, and it is possible to know exactly what kind of demand, and it is easy to determine the number of devices to be expanded. At the same time, it can also be easily deployed.

Detailed ways

The method of the present invention is described in detail below with reference to the accompanying drawings.

The invention provides a cluster storage system expansion method based on the same expansion module. The system adapts to the architecture and expansion requirements of the cluster storage system, and designs an expansion module that matches the capacity and performance, thereby ensuring that the cluster system maintains a balanced state of performance and capacity when expanding, and avoids capacity and performance. balanced situation.

The system consists of three module groups: performance module, capacity module and expansion module. The performance module is used to improve the performance of the cluster storage system, such as bandwidth, IOPS, etc. It is usually hardware such as a gateway or a controller, and the performance of the system can be improved by adding such devices.

The capacity module is used to increase the capacity of the system. With the increase of system data, it is often necessary to expand the capacity of the system to store more data. The capacity module is usually a hard disk, or a hardware device such as a JBOD, which is used to expand the capacity of the system to create a larger storage space and save more data.

The expansion steps are as follows: According to different cluster storage applications, determine a reasonable ratio of performance and capacity, bind the performance module and capacity module together according to this ratio, keep this ratio unchanged, and become an expansion module. Each expansion expands the same expansion module to ensure the performance and capacity balance of the entire system.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
