摘要: 服务器端文件系统不仅需要很大的容量,而且要为大量并发访问提供很高的I/O性能。该文提出一种把多个物理文件系统通过软件集成为一个逻辑文件系统的技术,很好地聚合了各个文件系统所在磁盘设备的带宽和容量,综合了不同文件系统在元数据和数据处理性能上的优势。性能测试结果表明,逻辑文件系统技术是一种构造支持高度并发访问的高性能文件系统的有效方法。

Abstract: File systems on the servers require both massive capacity and high I/O performance for large quantities of concurrent accesses. In this paper, a technology of building a logical file system by integrating a number of physical file systems is presented. It integrates the bandwidth and capacity of those physical file systems, and combines the performance of both meta-data and file data from different kinds of existing file systems. Performance evaluation result shows that the logical file system technology is an effective way of building high performance file system with the ability to support highly concurrent accesses.

Key words: file system, data layout, meta data
