摘要

VAXcluster是一个紧密耦合的多计算机系统，由两台或多台VAX计算机、一个或多个分层存储控制器(hsc)、两个或多个磁盘和一个耦合器组成。随着集群中VAX计算机数量的增加，VAX集群系统可用性的马尔可夫模型受到状态空间爆炸的影响。这就需要使用近似马尔可夫模型。作者利用随机Petri网建立了VAXcluster系统的精确可用性模型。

Stochastic Petri net modeling of VAXcluster system availability

A VAXcluster is a closely coupled multicomputer system that consists of two or more VAX computers, one or more hierarchical storage controllers (HSCs), two or more disks, and a tar coupler. The Markov model of VAX cluster system availability suffers from state-space explosion as the number of VAX computers in the cluster increases. This has necessitated the use of approximate Markov models. The authors develop exact availability models of VAXcluster systems by means of stochastic Petri nets.<>
