随着视频点播技术的不断发展，视频数据呈现出爆炸式增长，对文件存储及其扩容性方面提出了苛刻的要求。该文首先简单地描述了数据存储服务集群及该集群主要采用分布式平台Ha-doop，使用ZFS动态文件系统作为后端存储文件系统。接着简单介绍了ZFS的特性，其次着重介绍ZFS在HDFS上的集成设计，最后通过相应的实现和ZFS性能比较测试，证明ZFS文件系统在视频文件存储中具有很好的应用价值。

With the continuous development of VOD technology , data shows explosive growth , which raised demanding requirements in terms of file storage and expansion .Firstly, this paper briefly described the distrib-uted storage cluster which based on Hadoop , and it used ZFS file system as a back-end storage .Then give a brief introduction of ZFS feature and focus on the integrated design on HDFS .Finally , we designed a compara-tive tests to prove that the ZFS file system had a high application value in video storage system .
