A method, device, terminal and storage medium for multi-control storage balance

Abstract

The embodiment of the present application provides a method, device, terminal, and storage medium for multi-control storage balance. The method includes: obtaining the total flow information of the front-end and the flow information processed by the controller; setting the flow processing threshold of the controller; judging the control Whether the traffic information processed by the controller exceeds the traffic processing threshold: if yes, perform balanced allocation to the volume groups corresponding to the controller according to the total traffic information and the traffic information; otherwise, do not perform balanced allocation. The invention can realize dynamic balance, so that the data flow is directly delivered to the corresponding volume group by the controller without being transferred, thereby improving the data processing efficiency and storage performance.

Description

technical field [0001] The invention belongs to the technical field of multi-control storage, and in particular relates to a multi-control storage equalization method, device, terminal and storage medium. Background technique [0002] During the R&D and testing of storage, it was found that although the storage system of the existing software platform is an A-A storage system, the volume has the property of belonging to the controller, and the distribution of data must be carried out by the subordinate controller. In this way, during the process of reading and writing a large amount of data, the volume belonging to control A has limited ability to process data, and control B will receive the data and send it to control A through the PCIE channel, and then control A will send it. data to the underlying RAID. In this way, the data that should have been delivered directly to the underlying RAID through the A controller is transferred by the B controller. Therefore, this situa...

Problems solved by technology

[0002] During the R&D and testing of storage, it was found that although the storage system of the existing software platform is an A-A storage system, the volume has the attribute of the controller and the distribution of data must be performed by the subordinate controller.

In this way, during the process of reading and writing a large amount of data, the volume belonging to control A has limited ability to process data, and control B will receive the data and send it to control A through the PCIE channel, and then control A will send it. Data to underlying RAID

In this way, the data that should have been sent directly to the underlying RAID through the A controller has been transferred by the B controller

Therefore, this situation is not conducive to the improvement of data processing and storage performance.
