After creating the iSCSI targets and LUN on the NAS, you can use the iSCSI initiator
installed on your computer (Windows PC, Mac, or Linux) to connect to the iSCSI
targets and LUN and use the disk volumes as the virtual drives on your computer.
iSCSI LUN Capacity Expansion
The NAS supports expanding the capacity of an iSCSI LUN. To do so, follow the steps
below.
1. Locate an iSCSI LUN on the iSCSI target list in "iSCSI" > "Target Management". Click
"Modify".
2. Specify the capacity of the LUN. Note that the LUN capacity can be increased
many times up to the maximum limit but cannot be decreased.
3. Click "Apply" to save the settings.
Note:
An iSCSI LUN must be mapped to an iSCSI target before increasing the capacity.
For the type of LUN allocation, the maximum LUN capacity for thin provisioning is
32TB, while for instant allocation, the maximum LUN capacity is free space
available on the disk volume.
Optimizing iSCSI Performance
In the environments that require high performance storage, such as virtualization, users
are recommended to do the following to optimize the iSCSI and NAS hard disks
performance:
Use instant allocation: When creating an iSCSI LUN, select "Instant Allocation" to
achieve slightly higher iSCSI performance. However, the benefits of thin provisioning
will be lost.
Create m ultiple LUNs: Create multiple LUNs according to the processor number of
the NAS. The information can be checked in "System Status" > "Resource Monitor."
If the NAS has four processors, it is advised to create four or more LUNs to optimize
the iSCSI performance.
