| 摘 要： | 集群存储是解决大规模数据存储的重要方法。本文提出一种基于对象存储的集群存储系统结构，将文件分为目录路径元数据、文件元数据与数据对象三部分并独立管理。性能比较与分析表明，该方法能够支持超大规模的文件及超大容量的目录，明显地减少网络访问消息数量，提高访问性能，并且解决了因为修改目录而导致的大量元数捂迁移问题。

| Abstract: | Cluster storage is an important solution to large-scale data storage systems. In this paper, we present the architecture of a cluster storage system based on OSD in which the file is divided into directory path metadata, file metadata and data objects that are managed separately. Performance comparison and analysis results show that this method supports files with extremely high variance in size and directories containing a very large number of files, reduces obviously the number of network access messages, improves access performance,and resolves the problem of large metadata migration because of modifying the directory. |
