Non-Redundant Fibre Channel Fabric
The PDC/O1000 supports non-redundant Fibre Channel Fabrics. A
non-redundant Fibre Channel Fabric provides one I/O path between each
cluster node and its Fibre Channel SAN Switch and one I/O data path between
the Fibre Channel SAN Switch and each of its RA4000/RA4100 Arrays.
The switching hardware used distinguishes a non-redundant Fibre Channel
Fabric from a non-redundant FC-AL. A non-redundant Fibre Channel Fabric
uses one Fibre Channel SAN Switch installed between one Fibre Host Adapter
in each cluster node and the RA4000 Array Controller in each
RA4000/RA4100 Array for that fabric. These hardware components cannot be
shared by other non-redundant Fibre Channel Fabrics or non-redundant
FC-ALs in the PDC/O1000 cluster.
Each non-redundant Fibre Channel Fabric consists of the following hardware:
■ One Fibre Host Adapter in each node
■ One Fibre Channel SAN Switch
■ One or more RA4000/RA4100 Arrays, each containing one single-port
RA4000 Array Controller
■ A GBIC-SW module installed in each Fibre Host Adapter, each active
port on the Fibre Channel SAN Switch, and each array controller
■ Fibre Channel cables used to connect the Fibre Host Adapter in each
node to the Fibre Channel SAN Switch and the Fibre Channel SAN
Switch to each array controller
