Example Embodiment

[0028] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation mode and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] A computer network composed of storage devices that provide the same storage service externally is called a storage cluster. Each physical device is called a node. At the same time, the physical equipment, software facilities, and network addresses on all nodes in this cluster are collectively referred to as cluster resources, or resources for short, and the nodes where the resources are located are also called resource servers. In the present invention, in order to manage and switch these resources, a software facility is required to track, control and detect the availability of these r...

Abstract

The invention relates to a method for achieving high availability storage through resource rings. The different resource rings are formed between multiple nodes, resources are automatically switched on the resource rings through the corresponding heartbeat technology, and therefore high availability storage is achieved. The method includes the following steps that (1) instances are started and configuration files are obtained by the instances and read; (2) network lock objects are obtained by the instances and attempts for obtaining locks are sent through the obtained lock objects; (3) whether the locks are obtained or not is judged by the instances, if yes, the step (4) is executed, and if not, the step (5) is executed; (4) the main instance continuously sends heartbeat information at the set heartbeat interval, and configured resource services are started and executed one by one; (5) timers are started by the auxiliary instances and whether the heartbeat information sent by the main instance belonging to the resource ring is received overtime or not is judged. Compared with the prior art, the method has the advantages of being capable of saving investment, simple in configuration and the like.

Description

technical field [0001] The invention relates to a storage backup technology, in particular to a method for realizing high-availability storage by utilizing a resource ring. Background technique [0002] As human life is more and more closely integrated with computers, the stable operation of computers determines the efficiency and quality of human production and life. Therefore, the stability of computers is a key factor, especially as one of the core components of computers. The storage system plays the role of storing data. Because all the components of the computer are designed to process, transmit, calculate, and use the data stored in the storage system. These data may be personal and corporate business data, financial information, customer information, operation logs, etc. Loss or temporary unavailability of these data may cause irreparable losses. [0003] However, as a single computer device, it always has natural and unsolvable defects and uncontrollable external ...
