Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide

Cluster Architecture 2-43
Figure 2-16 shows a two-node PDC/O2000 that contains two redundant
FC-ALs. In this example, each redundant FC-AL has its own pair of Fibre
Host Adapters in each node, a pair of Storage Hubs or FC-AL Switches, and
two RA4000/RA4100 Arrays. In Figure 2-2, the hardware components that
constitute the second redundant FC-AL are shaded.
