iSCSI Essentials

target or delete the Target altogether.
To create a new Target, press the Add iSCSI target button.

G-RACK’s iSCSI Add Target page allows you to give your Target a name, associate it with a RAID-
Workspace, access credentials like username / password assignments (known by iSCSI initiators as
username & secret) as well as a multitude of performance and initiator parameters. G-RACK 12’s
default advanced parameter configuration has already been maximized for performance but if your
network or administrator choose to personalize the advanced parameters for iSCSI targets you will
find those attributes here. To expedite this lesson however all you need to proceed is a Target Name
and a File device.

Press the Save button to create the target, press the Reset button to return to the default settings or
press the Cancel button to exit the iSCSI Add Target page.
