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

Cluster Architecture 2-11
Multiple Redundant Fibre Channel Fabrics
The PDC/O2000 supports the use of multiple redundant Fibre Channel Fabrics
within the same cluster. You would install additional redundant Fibre Channel
Fabrics in a PDC/O2000 to:
■ Increase the amount of shared storage space available to the cluster’s
nodes. Each redundant Fibre Channel Fabric can connect to a finite
number of RA4000/RA4100 Arrays. These RA4000/RA4100 Arrays are
available only to the Fibre Host Adapters connected to that redundant
Fibre Channel Fabric.
■ Increase the cluster’s I/O performance.
Adding a second redundant Fibre Channel Fabric to the cluster involves
duplicating the hardware components used in the first redundant Fibre Channel
Fabric.
The maximum number of redundant Fibre Channel Fabrics you can install in a
PDC/O2000 cluster is restricted by the number of Fibre Host Adapters your
Compaq servers support. Refer to the Compaq server documentation for this
information.
