iSCSI Volumes

Use the iSCSI service to create one or more iSCSI volumes on the ReadyNAS.

iSCSI is not available on the ReadyNAS 1500.

The iSCSI (Internet SCSI) protocol allows clients called initiators to send SCSI commands to 
SCSI storage devices called targets on remote servers. It is a popular Storage Area Network 
(SAN) protocol, allowing organizations to consolidate storage into data center storage arrays, 
while providing hosts, such as databases and Web servers, with the illusion of 
locally-attached disks. Unlike Fibre Channel, which requires special-purpose cabling, iSCSI 
can be run over long distances using existing network infrastructure.

An iSCSI initiator sends SCSI commands over an IP network to an iSCSI target. Software to 

provide an iSCSI initiator is available for most mainstream operating systems. Unlike network 
file services where you access files in network share folders, the iSCSI target presents itself 
as a virtual block device and can be treated like a locally attached disk to the client system 
acting as the iSCSI initiator. Windows, for instance, could run FAT32 or NTFS on the iSCSI 
target device, and treat the device as though it was locally attached.

To configure an iSCSI target volume on the ReadyNAS, select Volumes > Volume Settings > 
iSCSI.

To enable iSCSI support, click Create iSCSI Target, and enter the name of the target you 
want, and the capacity you want to reserve for this target device. Maximum capacity is 
slightly less than the full free space on the ReadyNAS. If you want to enable authentication 
for access, enable CHAP authentication and specify the user name and password. The 
password needs to be at least 12 characters long.
