Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0058] Aiming at the high reliability and high availability required by the disk storage array, the present invention proposes a method for upgrading the firmware of the disk storage array, which satisfies the requirement that the disk storage array does not need to stop when the firmware is being upgraded, automatically detects the success of the upgrade, and does not need to interrupt the service. Require.

[0059] image 3 The hardware structure of the disk storage array controller according to the embodiment of the present invention is shown, including two controllers: a controller A and a controller B. Each controller includes a control unit with a timer, a firmware memory A and a BMC controller. Different from the prior art, the communication between the controlle...

Abstract

The invention discloses a firmware upgrading method of a double-controller disk memory array; before the firmware of any controller is upgraded, the main control power of the disk memory array and all data application services are transferred into another controller, and a controller is used for continuously providing the data application services in the upgrading process of the firmware, so that firmware upgrading without machine halt can be realized. The invention also discloses the double-controller disk memory array for realizing the method, and a controller thereof.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a dual-controller disk storage array, a method for upgrading firmware and a controller thereof. Background technique [0002] A disk storage array uses multiple disks to form an array as a single disk, and stores data in different disks in the form of striping. When accessing data, the related disks in the array act together, which greatly reduces the data access time and has better space utilization. Disk storage arrays are usually used as storage places for various important data in computer systems, which require extremely high reliability to ensure data security and stability. At the same time, disk storage arrays are required to provide 24-hour uninterrupted data service. [0003] In order to achieve high reliability and uninterrupted service characteristics, disk storage arrays usually adopt a dual-controller architecture. figure 1 It is a schematic diagram of t...
