4.2.6 Virtual Disk
You can use this function to add the iSCSI targets of other QNAP NAS or storage servers
to the NAS as the virtual disks for storage capacity expansion. The NAS supports
maximum 8 virtual disks.
Note:
The maximum size of a virtual disk the NAS supports is 16TB.
When the virtual disk (iSCSI target) was disconnected, the virtual disk will
disappear on the NAS interface and the NAS will try to connect to the target in two
minutes. If the target cannot be connected after two minutes, the status of the
virtual disk will become “Disconnected”.
To add a virtual disk to the NAS, make sure an iSCSI target has been created. Click “Add
Virtual Disk”.
