This paper discusses the development trend of mass storage system from such aspects as storage network technology, system architecture, data protection and green storage; then analyses related theories and essential technologies of the new generation mass storage called parallel mass storage system. It points out that the parallel mass storage system should be characterised by such advanced features as automatic load balance, high availability, deduplication, automatic tiered storage and green energy and so forth.%从存储网络技术、系统架构、数据保护、绿色存储等方面综合分析了海量存储系统的发展趋势,并对新一代海量存储-并行海量存储系统的相关理论和关键技术做了分析.并行海量存储系统应具有自动负载均衡、高可用、支持重复数据删除、自动分层存储、绿色节能等先进特性.
