Figure 63 shows an incorrect configuration of a single host with both iSCSI and
Fibre Channel connections.
Important: Do not cable the storage subsystem and host systems as shown in
Figure 63. A storage subsystem with the incorrect storage topology
might appear to be functional, but incorrect cabling can potentially
have unpredictable results.
Figure 64 on page 92 shows an example of a multiple-host, multiple-port,
multiple-switch configuration.
