Figure 1-1. Example of a two-node PDC/O5000 cluster

The PDC/O5000 can support redundant Fibre Channel Fabric Storage Area
Network (SAN) and redundant Fibre Channel Arbitrated Loop (FC-AL) SAN
topologies. In the example shown in Figure 1-1, the clustered nodes are
connected to the database on the shared storage subsystems through a
redundant Fibre Channel Fabric or redundant FC-AL. Clients access the
database through the client LAN, and the cluster nodes communicate across an
Ethernet cluster interconnect.
