Abstract: Existing researches on evaluation technology for networked storage system focus on performance testing，but there is no test tool which can evaluate the overall performance of networked storage systems comprehensively.To realize comprehensive evaluation for networked storage systems，the comprehensive evaluation indicator system is built by using the hierarchical model，then comprehensive evaluation system is designed and implemented.Detail description is introduced for the distributed file system performance test system；some test experiments of the aggregate bandwidth are performed.This comprehensive evaluation technology research will provide useful help for research and application of networked storage system.

Key words: storage evaluation, storage benchmark, performance benchmark, networked storage

摘要： 目前网络存储测评技术侧重于性能测评，没有一种测试工具能够全面反映存储系统的综合性能。采用分层结构模型建立全面的评测指标体系，设计和实现了网络存储综合测评系统，重点介绍了分布式文件系统的性能测试体系，对其聚合带宽做了测试实验。关于存储综合测评技术的研究成果可为网络存储研究和应用提供帮助。
