Set up your target and communications infrastructure
Before you install the iSCSI initiator on any of your servers or workstations, you must have something to which the initiator will connect. This can be one of the enterprise class arrays, such as those available from LeftHand, EqualLogic, Dell, or EMC or, if you’re on a tighter budget and want to build your own array, a target running iSCSI target software, such as StarWind.
I recommend that, whenever possible, you use either a physically separate infrastructure or separate IP network/VLAN for your iSCSI traffic. By doing so, you simplify troubleshooting and configuration later on.
