volume.

Manage iSCSI with Storage Manager

Go to Main Menu > Storage Manager
Synology DiskStation.
With DSM 3.0, you can manage up to 10 iSCSI Targets on one Synology DiskStation, and map iSCSI LUNs to
them.
iSCSI
iSCSI is an Internet Protocol based storage networking standard for linking data storage facilities. By carrying
SCSI commands over IP networks, iSCSI can facilitate data transfers over local area networks (LANs), wide
area networks (WANs), or the Internet.
Through iSCSI, the space on storage server will be regarded as local disks by client's operation system. But in
reality, all data transferred to the disk are actually transferred over network to the storage server.
iSCSI Target and LUN
In SCSI terminology, A LUN (logical unit number) represents an individually addressable (logical) SCSI device
that is part of a physical SCSI device (called "Target").
An iSCSI environment emulates the connection to a SCSI hard disk. An iSCSI Target is like a connection
interface, and LUNs are essentially numbered disk drives. When an iSCSI Target is connected by an iSCSI
initiator (a client), all the LUNs mapped to the iSCSI Target are virtually attached to the client's operation
system. Therefore, Initiators can establish and manage file systems on iSCSI LUNs, as they would a raw SCSI
or IDE hard drive.
