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 3-52 and Figure 3-53 on page
3-43 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.
