2. Connect the fibre channel cables from the SFP modules in the DS5100 and
DS5300 RAID controller host ports to either the SFP modules in the fibre
channel switch or the SFP modules of the host bus adapters.
Note:
When cabling directly from host bus adapters to host ports, be sure to
attach 8 Gbps devices to 8 Gbps host ports and 4 Gbps devices to 4
Gbps host ports.
Figure 71 shows the location on the RAID controllers where the host-system
cables connect.
3. Repeat steps 1 on page 108 and 2 for each additional redundant host
connection. You can create a maximum of eight redundant host connections, as
shown in Figure 72 on page 110.
Note:
Figure 72 on page 110 shows that the host ports are connected to eight
sets of FC host bus adapters (HBAs). You can replace one or all of these
sets of FC HBAs with FC switches as required.
