This dissertation presents a novel high performance file system for efficient small wirte : STFS. 本文提出了一种新型的针对小文件同步写优化的文件系统&STFS。
Beginning with the problems of solving the I / O bottleneck of high performance computer, this paper mainly analyzes the architecture, access mechanism, management mechanism and operating mechanism of PVFS, and provides an effective method for building high performance cluster file system. 从解决高性能计算机I/O瓶颈面临的问题着手,详细分析了并行文件系统(PVFS)的结构、存取机制、管理机制和工作机制,为高性能集群文件系统的建立提供了一种行之有效的解决方法。
As the I / O subsystem of cluster server, Parallel file system realizes the globally accessing of all files, devices and network resources distributed on the nodes of cluster. It is necessary to provider a high performance parallel file system to cluster server. 作为集群的I/O子系统,并行文件系统实现对分布在集群内各节点上的文件、设备和网络资源的全局访问,为集群服务器系统设计一个高性能的并行文件系统是很有必要的。
The primary fields in study of network storage are centralized in : storage of wide area network, cluster file system, novel high performance disk file system. 目前网络存储技术研究主要集中于:广域网存储技术、集群文件系统、新型磁盘文件系统三个方面。
JFS2 supports ordered journaling for high performance with sub-second file system recovery. JFS2支持预定的日志记录方式,可以提高较高的性能,并实现亚秒级文件系统恢复。
