iSCSI target node network connections and names

iSCSI target nodes can connect to the network in several ways:

  • Over Ethernet interfaces using software that is integrated into ONTAP.

  • Over multiple system interfaces, with an interface used for iSCSI that can also transmit traffic for other protocols, such as CIFS and NFS.

  • Using a unified target adapter (UTA) or a converged network adapter (CNA).

Every iSCSI node must have a node name.

The two formats, or type designators, for iSCSI node names are iqn and eui. The SVM iSCSI target always uses the iqn-type designator. The initiator can use either the iqn-type or eui-type designator.
