Realization Of Multi Campus Of Disaster Recovery And Disaster Recovery System Based On Virtualization

In order to ensure the security of data, research on data disaster recovery has become increasingly active. In this thesis, the multi campus disaster tolerant system realization of virtual research based on, through the study of existing virtualization system, found in the build process virtualization, the existence of virtualization is not quantitative and qualitative analysis, there is no ready-made method can perform accurate management of virtualization, in order to solve this problem, this paper especially the server merge rate algorithm, merging algorithm, rate of cluster server multi campus disaster recovery server consolidation rate and availability of the algorithm. At the same time, in view of the long HA detection in the process of the downtime, study of HA time optimization algorithm, the HA detection process from the original Master detection for permission to distribute the Slave collective detection, shorten detection time, improve the practicality of the HA.In the whole system was set up, the first from the overall situation of building multi campus of disaster recovery system based on virtualization of planning, the planning of disaster recovery system based on multi campus by two layer network, shared memory, storage and disaster recovery plan, in the detailed planning of the physical ESX host IP address, v Motion address, storage server and storage server is connected with the physical server network address are planning.Secondly, by using a single-mode fiber to multi campus switch remote connection, combined with IRF technology, the multi campus to form a two layer network, configuration of the two layer network.Configuration of the campus internal configuration of the shared memory, and the shared memory of the backup set, storage uses synchronous mode to make a backup of data.Virtual machine management center to build multi campus, realization of the two v Center server to the internet.Finally, in order to verify whether the disaster tolerance system virtualization to build on the success, finally the disaster recovery drill. From the actual drilling results can be seen, the scheme to build disaster tolerant system in daily work based on, if in the face of disaster, to protect the virtual data, and the key business designated to rapid recovery, the recovery effect.
