I researched a lot about storage system classes given at good universities this year. This had two reasons: The first was thispost of a researcher at NetApp, about the missing of a good storage or file system class book and secondly our own storage s…

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to network file systems and schemes, and more particularly, to a network file system that appears to its clients to be a single file system, while locating…

A file system layout apportions an underlying physical volume into one or more virtual volumes (vvols) of a storage system. The underlying physical volume is an aggregate comprising one or more groups of disks, such as RAID groups, of the storage sys…

An extensible file system format for portable storage media is provided. The extensible file system format includes the specification of primary and secondary directory entry types that may be custom defined. The primary and secondary directory entry…

FUSE: File system in USErspace. So what is a file system? A file system maps file paths to file contents and metadata. Metadata includes modification times, permissions, etc.…

目录 Union File System AUFS Docker是如何使用AUFS的 image layer 和 AUFS (docker版本不同可能会有区别,我的是在/var/lib/docker下的其他文件夹中) container layer 和AUFS(docker版本不同可能会有区别,我的是在/var/lib/docker下的其他文件夹中) 写一个AUFS Union File System Union File System, 简称UnionFS,是一种为Linux,FreeBSD,…

A mechanism is provided in a data processing system for reliable asynchronous solid-state device based de-duplication. Responsive to receiving a write request to write data to the file system, the mechanism sends the write request to the file system,…

兼容posix 接口的文件系统中我们不仅要测试 posix 接口是否兼容.随机读,随机写,顺序读,顺序写等读写模式下的性能.我们还要测试在不同工作负载条件下的文件系统的性能的情况:Filebench 是一款文件系统性能的自动化测试工具,它通过快速模拟真实应用服务器的负载来测试文件系统的性能.它不仅可以仿真文件系统微操作(如 copyfiles, createfiles, randomread, randomwrite ),而且可以仿真复杂的应用程序(如 varmail, fileserver,…

Introduction The network file system(NFS) is a client/service application that provides shared file storage for clients across a network. An NFS client grafts a remote file system onto the client's local file system name space and makes it behave lik…

谷歌三大核心技术(一)The Google File System中文版  The Google File System中文版 译者:alex 摘要 我们设计并实现了Google GFS文件系统,一个面向大规模数据密集型应用的.可伸缩的分布式文件系统.GFS虽然运行在廉价的普遍硬件设备上,但是它依然了提供灾难冗余的能力,为大量客户机提供了高性能的服务.   虽然GFS的设计目标与许多传统的分布式文件系统有很多相同之处,但是,我们的设计还是以我们对自己的应用的负载情况和技术环境的分析为基础的,不管…
