摘　　要：蓝鲸分布式文件系统(BWFS)克服了传统存储模式在性能、容量、共享、可扩展性、可管理性等方面的局限性,通过采用连接复制、通道切换、请求重构等网络容错软件技术,在无须额外硬件支持的前提下提高可用性。文章针对系统可用性,分析了BWFS所面临的网络相关故障,从系统软件角度阐述了BWFS所采用的网络容错技术,并对其效能进行了相应的测试比较。Blue whale distributed file system（BWFS） overcomes the shortcomings of traditional storage system in performance, capability, shareability, scalability, manageability and so no, It enhances the availability by adopting the soft-technology of connection-copy, channel-switch, and request-rebuild for network fault-tolerant without extra hardwave support. Aiming at the system availability, the article analyses the fault about network faced by BWFS, expatiates the technology of network fault-tolerant adopted by BWFS from the view of system software, tests and compares its efficiency.
