一种基于对象存储的文件系统的设计

Design and Implement of Object-based Storage File System

随着存储技术的飞速发展,对象存储设备面临如何高效存储并管理TB级容量数据的问题。针对Linux通用文件系统Ext2在处理大文件和巨型目录结构时存在的局限性,采用B+树结构设计并实现了一种基于连续块的对象文件系统。对该文件系统进行的测试结果表明,该文件系统的读写效率较高,而且随着文件的增大,性能保持稳定。

Along with the rapid development of storage technologies, object-based storage device faces the problem of efficient terabit level storage. In allusion to the limitation of Ext2 file system in Linux for processing large files and huge directories,by adopting B＋ tree structure,an object-based file system are designed and implemented, based on the assignment strategy of continuous blocks of data. The experiment results show that the implemented file system possesses a better data access efficiency than tranditinal file system, especially along with the capacity increasing of files, the performanee of this file system can still be retained steadily.
