Problems solved by technology

[0004] However, this method has certain limitations: when reading / writing data to the storage system, the main controller is usually used first, and it is impossible to use each controller to perform data access in a balanced and efficient manner.

Abstract

The present disclosure provides a load balancing method and device for a multi-control storage system. The backplane is used to package multiple ports to connect each controller, so that each controller can realize fast information transmission through the lines inside the backplane, and each controller can obtain the status of other controllers in real time. Designate the owning controller for each logical volume and use the internal information transmission channel of the backplane to synchronize the ownership information among the various controllers. When one of the controllers receives a data read and write request for a logical volume from the client, it determines the ownership controller of the logical volume through the ownership information, and hands over the business to the corresponding ownership controller. Data access can thereby be efficiently performed using a plurality of controllers.

Description

technical field [0001] The present disclosure relates to the field of data storage, in particular to a load balancing method and device for a multi-control storage system. Background technique [0002] Data has become the most important asset of all enterprises and individuals. Around the storage of data, various storage technologies have been born. In order to improve storage performance, ensure data security, increase storage capacity, and take into account storage costs, various types of storage systems have been designed. [0003] Among them, one of the working modes of the dual-controller storage system is the active-active mode: two or more controllers in the storage system provide services to the outside world at the same time, and each controller shares some resources and is active and standby for each other. After a fault occurs, switch its services to other controllers. To ensure high availability of the system and business continuity. [0004] However, this me...
