Embodiment Construction

[0033] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. The embodiments of the present invention and the combinations of the various features in the embodiments without conflict are within the protection scope of the present invention.

[0034] The embodiments of the present application can be flexibly expanded on the basis of an existing controller. There must be at least one controller added by the extension. When expanding an existing controller with a pair of controllers, the controllers added in the pair are redundant with each other.

[0035] In the embodiment of the present application, the working state of the controller includes active (active) state, takeover (takeover) state, taken over (standby) state and inacti...

Abstract

The invention discloses a disk array system capable of being dynamically adjusted and a method for adjusting the same, and overcomes the defect that the redundant disk arrays of a dual controller node cannot meet the storage requirement at present. The method comprises the following steps of: when controllers are added to the disk array system, comparing all controllers which are powered on with controllers which are successfully configured in the disk array system to obtain controllers which are powered on and not configured; and configuring controllers selected from the controllers which are powered on and not configured by a user in the disk array system, generating configuration files for the selected controllers, and synchronizing in the disk array system. By the embodiment of the invention, the disk array system can be flexibly expanded according to the user requirement, is high in reliability and meets the requirement of storing mass data.

Description

technical field [0001] The invention relates to a disk array system, in particular to a dynamically adjustable disk array system and an adjustment method for the system. Background technique [0002] With the rapid development of the information age, the amount of data is also increasing significantly. With the continuous improvement of data security and reliability requirements, the storage market is also undergoing changes and developments. The storage technology of a single controller node can no longer meet the increasing needs of users for storage space and storage flexibility. [0003] The disk array with dual controller nodes redundant with each other has become a popular and applicable storage product. With the expansion of business and the needs of different user environments, the current dual-controller node redundant disk array cannot meet the needs of users for system capacity, performance, flexibility and reliability. Contents of the invention [0004] The t...
