摘要：

In virtualized system, both redundancy and inspection-based maintenance has been used to maintain reliability. Analysis is often conducted on a single strategy; and the overall impact of a joint mechanism has not been analyzed in detail. So, a method is presented to analyze the reliability and performance of virtualized system with the joint mechanism. The reliability and performance indicators are based on the Markov chain constructed from the state transition diagram for the joint mechanism. Sensitivity analysis is conducted to analyze the impact of system configuration parameters change. Empirical studies show the process of evaluation model and sensitivity analysis. Changing the value of redundancy and inspection rate value, the system reliability and performance could be calculated through the analysis method. The increase of redundancy leads to the increase of reliability and performance rate. Whereas, the increase in inspection rate could only improve the performance to an extent. The influence of both parameters declines rapidly as the value increases.
