The loop device is a device driver that allows you to mount a file as a block device and then interpret the file system it represents.
loop设备是一个设备驱动程序，利用它可以将文件作为一个块设备挂载到系统中，然后就可以查看这个文件系统中的内容了。
Act as a forwarder of interrupts and requests from several virtual drivers: cobd (block device), conet (network), and cocon (console).
为来自某些虚拟驱动器(cobd(块设备)、conet(网络)、cocon(控制台))的中断和请求进行代理转发。
Users access the DRBD block devices as a traditional local block device or as a storage area network or network-attached storage solution.

The Network Block Device driver offers an access model that simulates a local block device by accessing the resource of remote server.
网络块设备的概念是把网络访问的远程资源虚拟成一个本地块设备。
Well, what really happens is that each block device, such as a hard drive partition, CD-ROM, or floppy disk, actually has a filesystem on it.
实际上，每一个区块设备(如硬盘驱动器分区、CD - ROM或者软盘)上都有一个文件系统。
The kernel module implements a driver for a virtual block device (which is replicated between a local disk and a remote disk across the network).
内核模块实现一个用于虚拟块设备(跨网络在本地磁盘与远程磁盘之间复制)的驱动程序。
The concept behind Software RAID is simple — it allows you to combine two or more block devices (usually disk partitions) into a single RAID device.
软件RAID的概念很简单——使您可以将两个或多个块设备(通常是磁盘分区)组合为单个RAID设备。
Since MTD_BLOCK devices provide block-device-like emulation, it is often preferable to create filesystems like FTL and JFFS2 on top of this emulation.
由于MTD_BLOCK设备提供象块设备那样的模拟，通常更可取的是在这个模拟基础上创建象FTL和JFFS2那样的文件系统。
MTD_CHAR provides raw character access to the flash, while MTD_BLOCK projects the flash as a normal block device (like an ide disk), on which a filesystem can be created.
MTD_CHAR提供对闪存的原始字符访问，而MTD_BLOCK将闪存设计为可以在上面创建文件系统的常规块设备(象ide磁盘)。
High availability with the Distributed Replicated Block Device (M. Tim Jones, developerworks, August 2010) provides an introduction to one method for data mirroring.
DistributedReplicatedBlock Device的高可用性(m .TimJones,developerworks, 2010年8月)讲述了一种数据镜像方法。

实际上，如果您想访问一个特定的块设备(如磁盘、分区、光盘驱动器等等)，事实上有几个不同的特殊文件可以引用。
The Distributed Replicated Block Device (DRBD) provides a networked version of data mirroring, classified under the redundant array of independent disks (RAID) taxonomy as RAID-1.
DistributedReplicatedBlock Device (DRBD)提供一个网络版的数据库镜像，属于冗余磁盘阵列(RAID)RAID - 1类。
First you specify the actual block device with a "device" line, and then you immediately follow it with a "raid-disk" entry that specifies its position in the array, starting with zero.
首先您用一个“device ”行指定实际的块设备，接下来用一个“ raid -disk ”条目指定其在阵列中的位置，从零开始。
Unlike most other filesystems like Ext2fs and JFFS2, which reside on top of the underlying block device, TMPFS sits directly on top of the VM. Thus mounting the TMPFS filesystem is a simple affair.
诸如Ext2fs和JFFS2等大多数其它文件系统都驻留在底层块设备之上，而tmpfs与它们不同，它直接位于VM上。
And while a traditional ramdisk is a block device and requires a MKFS command of some kind before you can actually use it, TMPFS is a filesystem, not a block device; you just mount it, and it's there.
而且传统的虚拟磁盘是个块设备，并需要一个mkfs之类的命令才能真正地使用它，tmpfs是一个文件系统，而不是块设备；您只是安装它，它就可以使用了。
