Embodiment Construction

[0026] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] The method for implementing node backup in the embodiment of the present invention mainly implements the control of node backup by the main management node. The working node performs backup; then, when the active-standby switchover is required, the main management node switches the hot-standby node into a working node, and switches the cold-standby node into a hot-standby node according to preset principles.

[0028] It can be seen that, in the embodiment of the present invention, it includes working nodes, hot standby nodes, and cold standby nodes, wherein the hot standby nodes are used to replace the working nodes, and the cold standby nodes are used to take over the hot standby nodes. There can be one or more hot standby nodes. Generally, the number of hot standby nodes is less than the number of working nodes. Since th...

Abstract

The invention discloses a method for realizing node standby and a system. The method comprises the steps of: distinguishing standby nodes into hot standby nodes and cold standby nodes by main management nodes, and configurating hot standby nodes and cold standby nodes for standby for working nodes; and when the main management nodes need main and standby reversing, reversing the hot standby nodes into the working nodes, and reversing the cold standby nodes into the hot standby nodes according to a pre-arranging principle. The invention fully guarantees the reliability of standby, meanwhile, can save resources, and improve the utilization rate of resources.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a method and system for realizing node backup. Background technique [0002] In the field of computer and communication, high reliability is an important index to measure equipment. Common ways to improve reliability are: [0003] 1.1+1 hot backup. Such as Figure 1-a As shown, in this way, there are two running nodes, one for business workload and one for backup. When the node that loads the business fails, the backup node takes over the failed node and continues to work. [0004] 2. Load sharing. Such as Figure 1-b As shown, in this way, both running nodes are loaded with business work. When a node fails, the business is migrated to another node. [0005] However, both methods have drawbacks in terms of resource usage efficiency. For 1+1 hot backup, the resources (such as CPU capacity) of the standby node are not fully utilized; and for load sharing, it is di...
