Dissertation Submitted to HuazhongUniversity of Science and Technology fortheDegreeofDoctorinPhilosophy Study on Architecture and Performance Evaluation of Disk Arrays Ph.D.Candidate:LUO Xin-guo Major:Computer Engineering Supervisor:Prof.

给出了公正的可靠性评价方法．首次以可靠性参数和容错的时间、容量余开销程度作为评价标准建立了RAID性能综合评价,此综合评价标准是一种全面考查RAID性能的有效方法.将RAID2与RAID5 结合的新型磁盘阵列RAID7具有可靠性高,时间余度和容量余度都适中的特点,是高性能阵列的优选结构从容错分析、可靠性评价、性能评价到新型阵列探索等创见性工作,对磁盘阵列的理论与技术发展具有重要的意义,并可应用于指导可靠性设计.关键词:磁盘阵列.存取信道.见余结构.性能评价.
