This paper analyzes the architecture of mass storage systems, introduces traditional clustering high availability strategies, and proposes a high availability stralegy specialized for mass storage system architecture. Then te3t is performed. Tesl result indicates thai when a server is down, the system can recover services in a very short time. The proposed strategy well satisfies (he high availability requirements for mass storage systems.%对海量存储系统架构进行介绍和分析,对传统集群高可用方案进行介绍,提出针对海量存储系统架构的高可用性保障方案,并对方案进行测试.测试结果表明,当服务器宕机后,系统能够在极短的时间里恢复服务.所设计的方案可以满足海量存储系统的高可用性需求.
