Abstract: 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 hardware 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 .

Key words: BWFS, Network fault-tolerant, Connection-copy, Channel-switch, Request-rebuild

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。
