Dual-controller iSCSI configurations:
The following illustration is an example of a multiple port, single-host configuration. A system that uses
multiple iSCSI ports can provide enhanced performance compared to a single-port iSCSI connection.
For cluster 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 3-55 on page 3-44 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.
