【 摘 要 】

In this scientific paper a specialized Markov chain for a reliability model of the fault-tolerant system with two types of failures, single batch repair and full restore after reaching the failed state is discussed. The generalized formulas for calculation of the system's stationary availability factor, the mean time to failure and the mean time to repair are also introduced. Application of the special type of the Markov chain in the reliability model of the nested disk array 'RAID-01' and calculation of mean time to data loss by using the generalized formulas are also discussed. The calculation examples of mean time to data loss of the 'RAID-01' array are also given.
