Iscsi Targets; Create An Iscsi Target - NETGEAR RNDU4000-100NAS Software Manual

iSCSI Targets

iSCSI is a storage networking standard that uses the Small Computer System Interface
(SCSI) to transfer data across a LAN. It is typically used in environments that use
applications that require block-level access to a storage system. For example, database
programs and virtualization programs often require block-level storage access. Most other
file-sharing protocols (for example, CIFS, NFS, and AFP) access storage systems at the file
level.
To use iSCSI, you must dedicate space on your ReadyNAS storage system by creating an
iSCSI target that has one or more logical unit numbers (LUNs) assigned to it. A LUN is a
division of space within an iSCSI target. You use an iSCSI initiator on your server, PC, or Mac
to connect to the LUN and make use of the connection just as you would a local hard disk
device.

Create an iSCSI Target

Each iSCSI target you create automatically creates a LUN 0 within the new iSCSI target. LUN
0 is required on each iSCSI target.
You can create additional LUNs, numbered from 1 to 254, for each target. You can allocate
space to each LUN individually. You can access each LUN as a different connection. For
more information, see
You can configure each iSCSI target to require CHAP authentication. CHAP authentication
requires anyone accessing LUNs on iSCSI targets on which it is enabled to provide login
credentials
