| 2 | |
| 3 | What is it: With this compiled in the kernel (or as a module), Linux |
| 4 | can use a remote server as one of its block devices. So every time |
| 5 | the client computer wants to read, e.g., /dev/nb0, it sends a |
| 6 | request over TCP to the server, which will reply with the data read. |

| 8 | to borrow disk space from another computer. |
| 9 | Unlike NFS, it is possible to put any filesystem on it, etc. |

| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 14 | The nbd kernel module need only be installed on the client |
| 15 | system, as the nbd-server is completely in userspace. In fact, |
| 16 | the nbd-server has been successfully ported to other operating |
| 17 | systems, including Windows. |
