8 Storage pool type: `iscsi`
10 iSCSI is a widely employed technology used to connect to storage
11 servers. Almost all storage vendors support iSCSI. There are also open
12 source iSCSI target solutions available,
13 e.g. http://www.openmediavault.org/[OpenMediaVault], which is based on
16 To use this backend, you need to install the `open-iscsi`
17 package. This is a standard Debian package, but it is not installed by
18 default to save resources.
20 # apt-get install open-iscsi
22 Low-level iscsi management task can be done using the `iscsiadm` tool.
28 The backend supports the common storage properties `content`, `nodes`,
29 `disable`, and the following iSCSI specific properties:
33 iSCSI portal (IP or DNS name with optional port).

48 TIP: If you want to use LVM on top of iSCSI, it make sense to set
49 `content none`. That way it is not possible to create VMs using iSCSI

54 ~~~~~~~~~~~~~~~~~~~~~~~
56 The iSCSI protocol does not define an interface to allocate or delete
57 data. Instead, that needs to be done on the target side and is vendor
58 specific. The target simply exports them as numbered LUNs. So {pve}
59 iSCSI volume names just encodes some information about the LUN as seen
66 iSCSI is a block level type storage, and provides no management
67 interface. So it is usually best to export one big LUN, and setup LVM
68 on top of that LUN. You can then use the LVM plugin to manage the
69 storage on that iSCSI LUN.
