Virtual machine data service system and method

Abstract

The invention discloses a virtual machine data service system and method. The system provides primary and backup sites, a host at the primary site and a host at the backup site share a storage interface, the system supports a storage active-active function, and the host at the primary site creates a virtual machine based on virtual machine data on a storage system volume and provides virtual machine services to the outside. When the host or a storage end at the primary site has failures, the host or the storage end at the primary site can be switched to the host or a storage end at the backupsite by using the shared storage interface and the storage active-active function, and the virtual machine services can be continuously provided to the outside. Thereby, even if the failures occur, the virtual machine services can also be provided to the outside, and the phenomena that the virtual machine is not crashed and the virtual machine services are uninterrupted can be ensured.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a virtual machine data service system and method. Background technique [0002] With the development and progress of storage technology, it is more and more common to provide virtual machine services in the storage field. [0003] At present, the Internet industry is increasingly developed. Both enterprises and consumers have an urgent demand for uninterrupted virtual machine services that are always online. For data storage, it is very important to ensure the continuity of data services, do a good job in data redundancy backup and fast switching of duties. [0004] However, current data storage systems generally have a single host and a single storage terminal, and host failure or storage failure is inevitable during operation. In this way, the virtual machine will be down, and then the service of the virtual machine will be interrupted. Contents of the invention [0005] ...

AI Technical Summary

Problems solved by technology

[0004] However, the current data storage system is generally a single host and a single storage terminal, and in the process of operation, host failure or storage failure is inevitable

In this way, the virtual machine will be down, which will cause the virtual machine service to be interrupted.
