| Abstract: | 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. |
