摘要
通过分析服务器群集系统的结构和工作原理,采用随机Petri网分别建立基本处理单元的软硬件可用性模型、共享数据磁盘可用性模型和服务器可用性模型。综合各个模型,得到服务器集群系统的可用性模型,通过仿真分析可知,采用集群技术可以有效提高服务器的可靠性。
By analysing the structure and working principle of server cluster system,stochastic Petri net method is adopted to set up respectively the availability models of the hardware and software of basic processing unit,the shared data memory disk and the server.The availability model of server cluster system is obtained by integrating these models.The simulating analyses reveal that the use of clustering technology can effectively improve the reliability of server system.
