Linux操作系统的磁盘、分区、磁盘恢复和RAID性能
Disks, Partitions, Volumes and RAID Performance with the Linux Operating System
摘要：
计算机操作系统中的块设备通常对应于磁盘或磁盘分区，用于在文件系统中存储文件。闪存不是唯一遵循块可访问字节流块设备模型的真实或虚拟设备。文件、远程设备甚至RAM都可以用作虚拟磁盘。本文介绍了在Linux操作系统中用作虚拟磁盘的块设备层的几种常见组合：磁盘分区、RAID文件、软件RAID、逻辑卷管理器和网络块设备。它使用不同的文件系统测量它们的相对性能：Ext2、Ext3、ReiserFS、JFS、XFS、NFS。
英文摘要：
Block devices in computer operating systems typically correspond to disks or disk partitions, and are used to store files in a filesystem. Disks are not the only real or virtual device which adhere to the block accessible stream of bytes block device model. Files, remote devices, or even RAM may be used as a virtual disks. This article examines several common combinations of block device layers used as virtual disks in the Linux operating system: disk partitions, loopback files, software RAID, Logical Volume Manager, and Network Block Devices. It measures their relative performance using different filesystems: Ext2, Ext3, ReiserFS, JFS, XFS,NFS.
