Direct-attached single-controller configurations in an iSCSI SAN

You can connect hosts using iSCSI directly to controllers. The number of hosts that can be directly connected to a controller or pair of controllers depends on the number of available Ethernet ports.

Note: Direct-attached configurations are not supported in HA pairs.
