Abstract
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)=0 and 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.关键词
