Term Explanation

iSNS

iSNS (Internet Storage Name Service) are often used in a local area network with complex storage deployment,

facilitating IT staffs to discover storage and manage iSCSI devices. You can register all the iSCSI Targets on

your DiskStation with the iSNS server on your network.

Manage iSCSI LUNs with Storage Manager

Go to Main Menu > Storage Manager and click the iSCSI LUN tab to manage iSCSI LUNs on your

Synology DiskStation. An iSCSI LUN (logical unit number) can be mapped to multiple iSCSI Targets to perform

storage operations such as read or write. You can create up to 10 or 256

iSCSI LUNs on your DiskStation.

There are 2 ways to create an iSCSI LUN:

 Designate several disks (Block-level).

 Designate a portion of your volume space (Regular Files).

If you create an iSCSI LUN with several disks, you can repair or expand it, or change its RAID type, just like using

a volume. (Please see Page 28 of this chapter for detailed information about volume management.)

To create an iSCSI LUN:

1 Click Create.

2 Select Custom.

3 Click Next.

4 Select the iSCSI LUN type you want to create.

 iSCSI LUN (Regular Files): The iSCSI LUN is created by designating a portion of the volume space for its

usage. Set up iSCSI LUN configuration, including Name, Location, Thin Provisioning, Capacity (GB),

iSCSI Target mapping.
