“…The presented Markov models suggest the ideal control. In this regard, the development of models is of interest, allowing to take into account the influence of control [21] on the reliability of the clusters of the organization under consideration. It is also of interest to study the criticality of the influence of these mechanisms on the potentially attainable level of reliability of cluster systems.…”

The Markov model of reliability of a failover cluster performing calculations in a cyber-physical system is considered. The continuity of the cluster computing process in the event of a failure of the physical resources of the servers is provided on the basis of virtualization technology and is associated with the migration of virtual machines. The difference in the proposed model is that it considers the restrictions on the allowable time of interruption of the computational process during cluster recovery. This limitation is due to the fact that, if two physical servers fail, then object management is lost, which is unacceptable. Failure occurs if their recovery time is longer than the maximum allowable time of interruption of the computing process. The modes of operation of the cluster with and without system recovery in the event of a failure of part of the system resources that do not lead to loss of continuity of the computing process are considered. The results of the article are aimed at the possibility of assessing the probability of cluster operability while supporting the continuity of computations and its running to failure, leading to the interruption of the computational (control) process beyond the maximum permissible time. As a result of the calculation example for the presented models, it was shown that the mean time to failure during recovery under conditions of supporting the continuity of the computing process increases by more than two orders of magnitude.

“…Models can be used in case of development of research in the direction of analysis the influence of control on the reliability of clusters, duplicated complexes [20]. At the same time, models can be taken as a basis that take into account the effect of the variability of organization of control of duplicated complexes on the probabilities of operable, inoperative and unsafe conditions of complex operation in conditions of undetected failures, including when duplicated calculations are performed with periodic and in particular optimal initialization of test control.…”

Abstract-Increased reliability of distributed systems can be achieved as a result of redundancy nodes implemented as duplicated computer complexes, which combined into clusters, and the efficiency of these clusters is largely depended on the intra and intercomplex data exchange organization. The options of intercomplex data exchange are considered from the point of view of a redundant channel, where the implementation of duplicated computing requires data transfer to the memory of the two computers of the addressed duplicated complex. The objective of this research is the development of the simulation models supporting the selection of design solutions for the intra-and intercomplex data exchange organization in the clusters of computer complexes aimed at the high reliability and performance increase in duplicated computing service. Based on the simulation models implemented on the AnyLogic platform, the efficiency areas of the considered intercomplex exchange options are established.
