Two-node PDC/O1000 cluster with one non-redundant Fibre
Channel Fabric
Using Multiple Non-Redundant Fibre Channel
Fabrics
The PDC/O1000 supports the use of multiple non-redundant Fibre Channel
Fabrics within the same cluster. Physically, this means that within each cluster
node, multiple Fibre Host Adapters are used to connect the nodes to different
sets of RA4000/RA4100 Arrays.
NOTE:
The PDC/O1000 supports the mixing of non-redundant Fibre Channel Fabrics and
non-redundant FC-ALs in the same cluster.
You would install additional non-redundant Fibre Channel Fabrics in a
PDC/O1000 cluster to:
■
Increase the amount of shared storage available to the cluster’s servers
when the Fibre Channel SAN Switch in your first Fibre Channel Fabric
is filled to capacity. With just one Fibre Channel Fabric present, your
shared storage resources are restricted by the number of ports available
on its Fibre Channel SAN Switch.
■
Increase the PDC/O1000 cluster’s I/O performance.
