【摘要】 随着高性能计算网络集群系统的高速发展,传统的网络存储架构——网络附加存储NAS和存储区域网SAN已越来越不能够满足系统对存储性能的要求。针对SAN和NAS的不足,新一代的网络存储技术——基于对象存储OBS成为了研究的热点。重点论述了基于对象存储的架构和特点,并针对基于对象存储的Luster文件系统进行了初步测试,通过和传统的NFS文件系统对比,分析了对象存储文件系统在可扩展性、性能、易用性和安全性等方面的优越性能。更多还原

【Abstract】 With the rapid development of high-performance computation cluster system,traditional network storage architectures,such as network attached storage(NAS) and storage area network(SAN),can’t adapt to the rapid development.Recently,a new generation network storage architecture-object-based storage(OBS) appeares.This paper discusses on the architecture and features of OBS,and tests the primary performances of Lustre file system based on OBS.According to the comparison of the performances of OBS and network file system(NFS),it analyzes the storage performance,expansibility,availability and security of OBS.更多还原
