The iSCSI protocol

The iSCSI protocol is implemented on both the host and the storage system.

On the host, the iSCSI protocol is implemented over either the host’s standard Ethernet interfaces or an HBA.

On the storage system, the iSCSI protocol can be implemented over the storage system’s standard Ethernet interface using one of the following:

A software driver that is integrated into Data ONTAP.
(Data ONTAP 7.1 and later) An iSCSI target HBA or an iSCSI TCP/IP offload engine (TOE) adapter.

The connection between the initiator and target uses a standard TCP/IP network. The storage system listens for iSCSI connections on TCP port 3260.

You need to make a note of the iSCSI node name so that you can supply it when you create an igroup.
