For cluster configurations, the following illustration is an example of a multiple-host,
multiple-port, single-controller, and redundant-path configuration.
You can replace the two gigabit Ethernet switches that are shown in Figure 26 and
Figure 27 with one large gigabit Ethernet switch that has the required number of
ports. Virtual local area network (VLAN) can also be used to isolate the two iSCSI
networks, instead of a single switch.
