Storage Hub
One Storage Hub can be installed between cluster nodes and shared storage
arrays in a PDC/O1000 cluster to create a non-redundant Fibre Channel
Arbitrated Loop (FC-AL).
The Storage Hub is one method for connecting one Fibre Host Adapter in each
node with the array controller in the RA4000/RA4100 Array. The Fibre Host
Adapter in each node, the Storage Hub, and the RA4000/RA41000 Arrays to
which they are connected belong to the same non-redundant FC-AL.
On the Storage Hub, one port is used by a Fibre Host Adapter in each node
and one port is used to connect to the array controller in each
RA4000/RA4100 Array.
The PDC/O1000 allows the use of either the Storage Hub 7 (with 7 ports) or
the Storage Hub 12 (with 12 ports). Using the Storage Hub 7 limits the total
number of nodes and RA4000/RA4100 Arrays you can install in a
non-redundant. For example, a non-redundant FC-AL with four Fibre Host
Adapters and four or more RA4000/RA4100 Arrays requires a Storage Hub
with at least 8 ports (a Storage Hub 12). In your selection of a Storage Hub,
you should also consider the likelihood of cluster growth.

Guide and the Compaq StorageWorks Fibre Channel Storage Hub 12
Installation Guide for further information about these products.
