Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The present invention proposes a device for ensuring the continuous availability of storage device resources with dual controllers, which is used to maintain the status of the controllers, and can handle them in time when abnormal conditions occur in the controllers. The abnormal conditions here include controller downtime, data link road failure etc. It can transfer the resources belonging to the faulty controller to the normal controller, and can release its own resources. Here, the resources belonging to the faulty controller are transferred to the normal controller, which not only refers to the transfer of storage resources, but also includes the network transfer of resources.

[0031] as attached figure 1 , figure 2 As shown, the implementation process is to set a set of identical modules in each controller and run in the backgr...

Abstract

The invention discloses a method for guaranteeing continuous availability of resources of a dual-controller storage device. According to the realization process of the method, two sets of identical modules are arranged in controllers respectively and operated on the background. Each set of modules comprise the sending module, the receiving module, the communication processing module, the decision module, the resource processing module, the resource takeover module and the resource switching-back module. Compared with the prior art, the method for guaranteeing the continuous availability of the resources of the dual-controller storage device guarantees that the using of storage resources is not influenced when a single controller breaks down, the currently supplied services are not influenced, and the brain-split situation can be barely generated; when the method is applied to products, the reliability of the products can be improved remarkably, continuous supporting to user services is improved, the products are improved greatly, the practicability is high, and the method is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a device with strong practicability and guaranteed continuous availability of storage device resources with dual controllers. Background technique [0002] Today, with the rapid development of storage devices, single-controller storage devices have become more and more difficult to deal with large-scale applications, and are prone to failures that cause application downtime. Therefore, most of the more popular storage devices have now been replaced with dual-controller storage, four-controller storage or even eight-controller storage devices. Based on the storage device in the prior art, an apparatus for ensuring continuous availability of resources of a dual-controller storage device is now provided. Contents of the invention [0003] The technical task of the present invention is to provide a device with strong practicability and guaranteed continuous availability of dual-...
