Disaster recovery switching method and device based on virtual machine

Abstract

The invention discloses a disaster recovery switching method and device based on a virtual machine. The disaster recovery switching method comprises steps of transmitting a detection order to a switch positioned on a service plane side according to a preset time interval in order to detect whether connection of a gateway of the service plane is normal or not, if the gateway connection of the service plane is detected to be not normal according to the detection order, reporting to an operation system and sending alarming information, obtaining a control order transmitted by the operation system when the operation system determines the switch has faults according to the alarming information, and switching a host machine to a memory plane according to the control order. The embodiment of the disaster recovery switching method and device can transfer a flow of the service plane to the memory plane on the basis of that the current hardware facility is not changed, multiplex a current storage channel to bear service transmission during a fault period, reduce resource waste, guarantee that the service that the virtual machine on the host machine provides to the external is not interrupted and dramatically improve reliability of the disaster recovery capability and service of the virtual machine during the external service of the virtual machine.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a virtual machine-based disaster recovery switching method and device. Background technique [0002] A virtual machine (VM, Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. In the existing solution, the virtual machine can provide external services through the service channel, where the service channel is: virtual machine -> br1 (Bridge, bridge) -> eth1 (Ethernet, Ethernet port) -> tor1 (located in the network peripheral switch)->lc (core switch)->external network gateway; it can also provide customers with distributed storage services through the storage channel, where the storage channel is: virtual machine disk->host machine block device->eth0->tor0- >lc->storage server. [0003] During the research and ...

AI Technical Summary

Problems solved by technology

[0003] During the research and practice of the prior art, the inventors of the present invention found that, in this solution, if any part of the business channel between eth1 and the gateway of the external network fails, such as the switch is powered off or the hardware is damaged, the business The channel will be interrupted, and the virtual machine will not be able to continue to provide external services. It can only wait for the staff to repair it, which will have a great impact on users, poor disaster recovery capabilities, and low service reliability.

If a new backup service channel is added, a large amount of investment is required and the existing network needs to be transformed, and the newly added service channel will be idle most of the time, resulting in a great waste of resources
