So every time + the client computer wants to read, e.g., /dev/nb0, it sends a + request over TCP to the server, which will reply with the data read. + This can be used for stations with low disk space (or even diskless) + to borrow disk space from another computer. + Unlike NFS, it is possible to put any filesystem on it, etc. + + For more information, or to download the nbd-client and nbd-server + tools, go to http://nbd.sf.net/. + + The nbd kernel module need only be installed on the client + system, as the nbd-server is completely in userspace. In fact, + the nbd-server has been successfully ported to other operating + systems, including Windows. |
