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 kernel module implements a driver for a virtual block device (which is replicated between a local disk and a remote disk across the network).
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。
Act as a forwarder of interrupts and requests from several virtual drivers: cobd (block device), conet (network), and cocon (console).
这和Linux虚拟磁盘如何使用大相径庭；标准的Linux虚拟磁盘是块设备，所以在使用它们之前必须用您选择的文件系统将其格式化。
This is very different from how Linux ramdisks are used; standard Linux ramdisks are block devices, so they must be formatted with a filesystem of your choice before you can use them.
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。
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.
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。
The Network Block Device driver offers an access model that simulates a local block device by accessing the resource of remote server.
