iSCSI Target
iSCSI Target is a disk space on the network drive. It can be mounted on a network by the iSCSI server or NAS storage device (iSCSI initiators) as a form of extended storage space.

You can create one or more iSCSI Targets in TNAS (up to a maximum of 32).

To Create an iSCSI Target:
1. Go to TOS Desktop> Control Panel> Storage Manager> iSCSI Target> Settings;
2. Check "Enable iSCSI target service", then click "Apply";
3. Go to TOS Desktop> Control Panel> Storage Management> iSCSI Target> iSCSI Target list, then click "Create";
4. Fill in the iSCSI Target name and alias. If you have checked "Data Summary" and/or "Header Summary", then the contents of these items will be validated when the iSCSI initiator comes online with the iSCSI Target;
5. Create iSCSI LUN;

6. Click "Create".

iSCSI LUN is a logical disk in iSCSI Target. One iSCSI Target can have one or more iSCSI LUNs. iSCSI LUNs are configured in two ways:

Thin Provisioning: This flexibly allocates capacities to iSCSI LUNs without being limited by the current system's actual capacity. If the allocated capacity is greater than the available storage capacity of TNAS, you can expand this storage capacity to meet the iSCSI LUN future capacity requirements.
Instant Allocation: The capacity allocated by iSCSI LUN cannot be greater than the available storage capacity of TNAS. Please note that this allocation takes a long time.

CHAP Authentication: If a password is required, password verification must be performed on the iSCSI initiator when mounted. The password can not be less than 12 characters.
iSCSI LUN Storage Capacity: This can be defined upon creation, and modified after creation. However, this storage capacity can only be increased (not decreased).
