| 摘 要： | 可靠性对大规模存储系统至关重要,在大规模存储系统中设备失效日趋频繁,副本技术成为提高系统可靠性的主流技术之一.基于Markov模型,针对多副本存储系统建立了度量系统可靠性的理论模型.该模型能够反应失效检测延迟对系统可靠性的影响.通过该模型还可以度量存储系统关键参数如系统规模、副本阶数、单节点容量、单节点平均失效时间、数据对象平均大小、平均修复带宽等对系统可靠性的影响,从而为存储系统的设计提供理论基础.

| Abstract: | Nowadays storage systems become larger and larger,so the number of storage devices is increasing rapidly,which makes storage device failure occur quite frequently in large scale storage systems.Data replica technology begins to be adopted prevalently to enhance storage system reliability.When designing a large scale storage system,there are many factors that could affect the reliability of the storage system,such as failure detection latency,storage node capacity selection,data object size design,replica ra... |
