RESUMEN
Taking the disaster recovery system in the data center of Quanzhou Orthopedic-Traumatological Hospital Affiliated to Fujian University of Traditional Chinese Medicine as an example,the paper introduces how to use all kinds of high-performance equipment and advanced VSS virtual exchange,VMware server virtualization and VPLEX storage virtualization technologies to eliminate the single-point fault hidden danger and realizes the high available data center disaster recovery construction with RTO =0.
RESUMEN
Objective To study VMware storage virtualization technology to optimize hospital virtual platform in single-point failure,disk array,server performance and etc.Methods VMware software was used to define the concepts and methods for storage,virtualize the server and storage,update the hardware equipment in the platform and design virtual storage.Results On-line data capacity extension was executed for the server,and the difficulty was relieved in system management.The system availability was enhanced by increasing the system performance while eliminating single-point failure in information storage.Conclusion Virtual storage technology gains advantages in high extensibility,flexibility and safety,and thus is worthy promoting in futural hospital practically.

RESUMEN
Contemporary hospital information systems normally contain multiple applications,which are traditionally deployed as one application per server.More servers in the system will incur high system costs,low server efficiency and poor management and maintenance.The information system reform project of Wuxi Maternal and Child Health Hospital called into play the virtualization based on VMware.The project brought forth a number of merits,namely sizably raising efficiency of servers integration,simplifying server group management,reducing cost and promoting hospital informationization.
RESUMEN
At present,most applications remain in the Service is a single application system with unique hardware system and every deployment of an application system needs to add new hardware device and will bring a lot of additional costs. Application systems will be migrated to the virtual application structure which will effectively improve equipment utilization,reduce purchase costs and operating costs and at the same time,it will bring many benefits to the deployment and operational management and disaster recovery,etc.
RESUMEN
Objective To build high availability cluster using VMware to improve availability of hospital information system.Methods Virtual machines were installed in VMware server to act as backup servers.High availability software continuously detected status of physical servers using heartbeat signals.Results When physical servers failed,high availability cluster switched services automatically.The business switched to virtual machine quickly and smoothly.Conclusion High availability cluster based on VMware can improve HIS availability and lower implementation costs effectively.
