医院容灾系统建设与虚拟化技术

摘要

The medical information of hospitals covers a wide range of contents and has mass data. Therefore, once the data is destroyed or lost, it will cause an incalculable damage to the hospital. However, the traditional disaster recovery solutions are hard to be built, their costs are high and the cost of sequence system maintenance is also high. The disaster recovery system based on the virtualization technology can effectively reduce costs and improve the efficiency of resource utilization. By making full use of existing equipments, the high availability clusters of hospital information system,built by continuous data protection and virtual machine technology, can effectively realize high availability and real-time data backup of the hospital information system, save the cost and ensure the uninterrupted running of hospitals.%医院的医疗信息覆盖面广,数据量大,一旦数据破坏或丢失、就会给医院造成不可估量的损失,但传统的容灾方案存在建设难度高、成本居高不下、后期系统维护成本高等问题.为了解决这些问题,利用虚拟化技术进行容灾备份系统建设是降低建设成本、提高资源利用率的有效方法.采用持续数据保护和虚拟机技术共同构建医院信息系统高可用集群,充分利用现有设备,可以有效地实现医院信息系统的高可用性和数据的实时备份,同时节约了成本,保证工作的不间断运行.
