the SFP modules of the host bus adapters. Figure 54 shows the location on the
RAID controllers of the DS5020 storage subsystem where the host-system
cables connect.
Note: DS5020 controllers with four Fibre Channel host ports is shown in the
following illustration. The host channel configuration in your DS5020
hardware might differ slightly from the following illustration.
3. Repeat steps 1 on page 82 and 2 on page 82 for each additional redundant
host connection. You can create two redundant host connections for the
DS5020 storage subsystem, as shown in Figure 55 on page 84, or a maximum
of four redundant host connections (not shown). With four redundant host
connections, you can have a connection to a DS5020 Fibre Channel host bus
adapter or to Fibre Channel switch ports.
