Switched Fabric Connection in Single Controller
In this type of connection, each SFP port is connected to an FC switch then to the host board adapters.
Each logical partition is mapped to a single host channel ID. If you prefer path redundancy, you can map
a logical partition to IDs residing on two different channels.

Data Path Connection
The data paths are connected to one or more FC switches. The SAN
management measures, such as switch zoning and port binding, must
be taken to avoid multiple servers from accessing the same LUN.
If multiple servers detect a mapped volume, you have to avoid access contention using file locking
software, port binding, or zoning feature of the FC switches, which limits the access from host to a
specific LUN. If you have two servers in a clustered configuration, the clustering software will perform
the access control.
