Embodiment Construction

[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] figure 1 It is a flow chart of a faulty interface node takeover method according to one aspect of the present invention. exist figure 1 middle:

[0022] Step S100: When an interface node (for example, a server) in the system fails, obtain the virtual IP address of the failed interface node and the physical address of the normal interface node that has not failed.

[0023] Step S102: Find a takeover interface node for taking over the faulty interface node among multiple normal interface nodes according to the virtual IP address allocation strategy, and allocate a virtual IP address to the takeover interface node. Wherein, the virtual IP address allocation s...

Abstract

The invention discloses a method for taking over a fault interface node in a storage system. The method comprises the steps of S1: obtaining a virtual Internet protocol (IP) address of the fault interface node and a normal interface node; S2: finding out a taking-over interface node which takes over the fault interface node in the normal interface node according to a virtual IP address allocation strategy, and allocating the virtual IP address to the taking-over interface node; and S3: enabling the virtual IP address to take effect on the taking-over interface node according to an address resolution protocol (ARP) cheating method. Besides, the invention also discloses a system for taking over the fault interface node. The system comprises the fault interface node, the normal interface node, a fault interface node virtual IP address acquisition module, a normal interface node acquisition module, a virtual IP address allocation module and an ARP cheating module. By the aid of the method and the system for taking over the fault interface node, the fault interface node can be taken over smoothly.

Description

technical field [0001] The present invention basically relates to the field of networks, and more specifically, relates to a method and system for taking over a failed interface node. Background technique [0002] The rapid speed of the Internet industry, the increasing demand for large-block file storage, massive file storage, and network storage have promoted the rapid development of cloud storage. Cloud storage can realize the efficient storage of massive data in the cloud. How to ensure the reliability of the cloud storage system is of great significance to ensure the high availability of cloud storage. [0003] The current mainstream cloud storage system generally adopts a static reliability guarantee technology - dual-machine hot backup technology. Dual-machine hot backup technology is a high fault-tolerant application scheme combining software and hardware. The program consists of two server systems, an external shared disk array and corresponding dual-machine hot ba...
