SAN系统拓扑结构及其应用

【摘要】 首先分析了SAN的三种拓扑结构 ,专属点对点连接、仲裁回路、交换结构 ,并对每一种拓扑结构进行了性能分析。然后分析了SAN的三种最基本的应用 :群集、备份及灾难恢复。最后 ,对现在流行的三种存储方案SAN、NAS、DAS进行了简单的比较 ,从而得出今后存储的发展方向为SAN更多还原

【Abstract】 The three topologies(Dedicated Point-to-point Connection,Arbitrated Loop,Switch Fabric)of SAN and their performance and SAN’s three applications(Clustering,Backup,Disaster Recovery)are analyzed in this paper.Comparisons among SAN and NAS and DAS are made and results show that SAN will be the popular storage in the future.更多还原
