Adding a second non-redundant Fibre Channel Fabric to the PDC/O1000
involves duplicating the hardware components used in the first Fibre Channel
Fabric.
The maximum number of non-redundant Fibre Channel Fabrics you can install
in a PDC/O1000 is restricted by the number of Fibre Host Adapters your
Compaq ProLiant servers support. Refer to the Compaq ProLiant server
documentation for this information.
Figure 2-3 shows a four-node PDC/O1000 cluster with two non-redundant
Fibre Channel Fabrics. Each Fibre Channel Fabric has its own Fibre Host
Adapter in every node, one Fibre Channel SAN Switch, and one or more
RA4000/RA4100 Arrays. In Figure 2-3, the hardware components that
constitute the second Fibre Channel Fabric are shaded.

Figure 2-3. PDC/O1000 cluster with two non-redundant Fibre Channel Fabrics
In Figure 2-3, the original non-redundant Fibre Channel Fabric connects to
eight RA4000/RA4100 Arrays. The second Fibre Channel Fabric connects to
four RA4000/RA4100 Arrays.
