Some key technologies of deploying high availability redundant cluster system and dependability analysis
一种高可用性冗余集群的关键技术及可信性分析

Some key technologies for deploying high availability cluster system were discussed in this paper. An adaptive fault-tolerance method based on task table was presented. The designing idea of the adaptive fault-tolerance algorithm and the implementation of the algorithm were described in detail. Finally, the dependability model with Petri-net was also presented. According to the dependability analysis of the high availability cluster, it shows that the cluster system in this paper has high availability to be used in critical application field.
