摘要
结合设计应用于金融领域的,由曙光天阔服务器搭建的高可用机群系统,从硬件、系统软件和应用服务软件三个方面进行分析,提出对系统可用性进行估算的一种方法,计算出所设计的高可用机群系统的可用性,证明了该高可用机群系统的可用性达到99.999%.
In connection with a cluster system with high availability was made of super server ＂Shuguang- Tiankuo＂ to be used in financial field. The system was analyzed from three aspects： hardware, OS software, and application service software, and a method was presented to assess the cluster system＇s availability. Then, by using this method, the availability of the cluster system designed with high availability has been calculated, witnessing that this high-availability cluster system has a quite high such an availability as 99. 999 % and could meet the requirements of users.
