医院私有云双活数据中心的研究与设计

Research and design of dual-active data center of private cloud in hospital

目的:研究与设计一套既满足医疗业务连续性需求、又能保证数据的容灾备份系统,实现资源最大利用率的数据中心方案。方法:针对医院数据中心建设现状,结合云计算、虚拟化、存储双活、数据库集群等技术,通过建设计算、存储、网络、桌面和安全5个资源池,最终实现生产云、测试云、灾备云、桌面云和安全云5个医院私有云的应用,建立一套恢复点目标(RPO)=0和恢复时间目标(RTO)≈0的医院私有云双活数据中心方案。结果:设计出一套具有高可用、高性能、高扩展和高便捷管理的医院私有云双活数据中心,实现所有数据中心的管理和操作简单便捷,并提高了数据资源的利用率。结论:私有云双活数据中心在满足业务连续性需求的前提下,可最大限度地实现资源的充分利用,节省IT基础设施的投资建设成本。

Objective:To study and design a disaster recovery backup system that not only can meet the continuous requirement of medical services but also can ensure data so as to achieve a data center plan that has maximum utilization ratio of resources.Methods:Face to the current situation of constructing data center of hospital,the cloud computing,virtualization technique,dual-active storage and database cluster were combined in the research,and through established calculation,storage,network,desktop and safety to finally achieve five private cloud included of producing cloud,testing cloud,disaster recovery cloud,desktop cloud and secure cloud.And then,based on above design to establish a plan about dual-active data center of private cloud included of recovery point objectives(RPO)=0and recovery time objective(RTO)≈0.Results:This research has designed a dual-data center of private cloud with high availability,high performance,high expansion and high convenience management.It has realized simple and convenient management and operation for all data centers,and enhanced the utilization ratio of data resources.Conclusion:The dual-active data center of private cloud can farthest realize full use for resource and save investment and construction costs of IT infrastructure under the preconditions of meeting the continuous requirement of medical services.
