E_Port An ISL (Interswitch link) port. A switch port that connects switches together to
form a fabric.
Edge switch A fabric switch that connects host, storage, or other devices, such as Brocade
Access Gateway, to the fabric.
F_Port A fabric port. A switch port that connects a host, HBA (host bus adaptor), or
storage device to the SAN. On Brocade Access Gateway, the F_Port connects
to a host or a target.
Mapping In Access Gateway mapping defines the routes between devices or F_Ports to
the fabric facing ports (N_Ports).
N_Port 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.
NPIV 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.
