deployment complexity by leveraging N_Port ID Virtualization (NPIV).
Any host or target device with a distinct WWN. Devices may be physical or
virtual.
A port configured as a diagnostic port on an AG switch, connected fabric
switch, or connected cascaded AG switch to run diagnostic tests between the
ports and test the link.
An interswitch link (ISL) port. A switch port that connects switches together to
form a fabric.
A fabric switch that connects host, storage, or other devices, such as Brocade
Access Gateway, to the fabric.
A fabric port. A switch port that connects a host, host bus adapter (HBA), or
storage device to the SAN. On Brocade Access Gateway, the F_Port connects
to a host or a target.
In Access Gateway, mapping defines the routes between devices or F_Ports to
the fabric facing ports (N_Ports).
A node port. A Fibre Channel host or storage port in a fabric or point-to-point
connection. On Brocade Access Gateway, the N_Port connects to the Edge
switch.
N_Port ID Virtualization. This is a Fibre Channel facility allowing multiple
N_Port IDs to share a single physical N_Port. This allows multiple Fibre
Channel initiators to occupy a single physical port, easing hardware
requirements in storage area network design, especially for virtual SANs.
