11 | This backend provides basically the same functionality as the Open-iSCSI backed, |
12 | but uses a user-level library to implement it. You need to install the | |
13 | `libiscsi-bin` package in order to use this backend. | |

15 | It should be noted that there are no kernel drivers involved, so this | |
16 | can be viewed as performance optimization. But this comes with the | |
17 | drawback that you cannot use LVM on top of such iSCSI LUN. So you need | |
18 | to manage all space allocations at the storage server side. | |

23 | The user mode iSCSI backend uses the same configuration options as the | |
24 | Open-iSCSI backed. | |
