ANALYSIS OF FAILURE SCENARIOS OF CLUSTER STRUCTURES OF AUTOMATED CONTROL SYSTEMS
The article is devoted to the problem of the improvement of reliability and fault tolerance of automated control systems. To solve these problems it is proposed to use the cluster organization of structure of the systems of this class. In this case, the cluster is a group of computers connected by communication channels that can be treated as a single hardware resource. Application of several computers in datacenters poses the problem of computers (or nodes) selection. It is necessary to perform failure analysis of cluster structure of the automated control system in order to find out an adequate number of nodes. Thus we must consider all failure scenarios of cluster structure. The article provides the reader with an analysis of failure scenarios of cluster structure of the automated control system applied at the high-tech enterprise. The given analysis allows choosing the best variant of formation of the cluster structure of the automated control system.
