Figure 69. Single-host, multiple-port, dual-controller iSCSI configuration
For host configurations, the following illustration is an example of a multiple-host,
multiple-port, and redundant path and controller configuration.
You can replace the two gigabit Ethernet switches that are shown in Figure 70 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.
