The analysis of high availability cluster technology
Abstract:In recent years,high availability cluster technology has been widely applied in the enterprise,and the requirements for the high avaliability of computer system is became more and more higher. In this paper, on the basis of the analysis for the related concepts and key technology of high avalilability cluster,making a detail desription from the system structure,function module and the operation principle of the key software for the high availability.By making a introduction about the basic theory knowledge of high availability cluster technology,it provides important reference meanings for the next stage of the work. direction.
Keywords: High availability cluster technology High availability cluster Heartbeat Distributed Replicated Block Device SLE HA
