摘　　要：为了应对医院信息系统停机、业务中断等风险,我院建设了双活数据中心。当其中任一个数据中心的网络交换机、服务器、存储、SAN交换机等出现故障时,应用可以在数秒内自动切换本数据中心其它冗余设备上或者另一个数据中心,保证了医院业务系统的持续运行;为了解决误删除、数据库、病毒入侵等逻辑错误,部署了虚拟化环境下的持续数据保软件,保证数据恢复RTO达到分钟到级别、RPO达到秒级别,为我院HIS、EMR等应用系统不间断的运行提供了坚实的保障;双活数据中心还解决了传统的容灾机房网络设备长期处于Active-Standby状态并耗费大量能源的问题、提高医院的经济效益。In order to deal with the risk of hospital information system downtime and business interruption, our hospital has built a double live data center. When any of the network switches, servers, storage, and SAN switches in any data center failed, the application can automatically switch to other redundant devices or another data center in a few seconds to ensure the continuous operation of the hospital business system. In order to solve the logical errors such as deleting database and virus intrusion, the continuous data guarantee software under the virtualization environment is deployed to ensure that the data recovery RTO reaches the level of minutes to the second level of RPO, and provides a solid guarantee for the uninterrupted operation of HIS and EMR applications in our hospital.The double live data center also solves the problem that the traditional network equipment in the disaster tolerant machine room is in the Active-Standby state for a long time and consumes a lot of energy, and improves the economic benefit of the hospital.
