Intercomplex exchange alternatives in duplicated computing complex clusters

Abstract

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.
