Abstract: The paper builds a theoretical HA model based on binary component model and Markov process. A quantitative analysis on improving system availability is made. An HA solution is proposed upon the iSCSI multi-level storage system , and a test result is given and analyzed.

摘要： 分别用二元元件模型和马尔可夫链建立了高可用系统的理论模型,并从中量化分析了提高系统高可用性的关键指标和方法,并且结合iSCSI协议的具体特性和iSCSI多级存储系统的实现方案,提出了具有针对性的高可用解决方案,最后量化分析了测试结果。
