IBM DS3500

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 60 and
Figure 61 on page 62 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.
