Abstract: VAX-cluster systems are closely coupled configurations of VAX computers and storage devices. This paper discusses an availability model of heterogeneous multiprocessor based VAX-cluster systems using stochastic Petri nets. The model includes detailed failure/recovery behaviors like cluster state transitions, re-reboots and faulty repair. Failure/recovery interdependencies between the multiprocessors are also modeled. Unlike a Markov model the stochastic Petri net model is not configuration specific, and can be used to analyze various cluster configurations.
Keywords: heterogeneous multiprocessor VAX cluster system; closely coupled cluster configuration; stochastic net; failure recovery; reboot.
