Figure 2-8 shows a four-node PDC/O1000 cluster with two non-redundant
FC-ALs. Each FC-AL has its own Fibre Host Adapter in every node, one
Storage Hub or FC-AL Switch, and one or more RA4000/RA4100 Arrays. In
Figure 2-8, the hardware components that constitute the second non-redundant
FC-AL are shaded.

In Figure 2-8, the original non-redundant FC-AL connects to eight
RA4000/RA4100 Arrays. The second non-redundant FC-AL connects to four
RA4000/RA4100 Arrays.
