broadcast.
multi-switch fabric
Fibre Channel fabric created by linking more than one director or switching device within a
fabric.
name server
Program that translates names from one form into another. For example, the domain name
service (DNS) translates domain names into IP addresses.

Node port (N_Port) access management that allows N_Ports to communicate if and only if
they belong to a common name server zone.

node
In Fibre Channel terminology, node refers to an end device (server or storage device) that is or
can be connected to a switched fabric.
node port (N_Port)
Physical interface within an end device which can connect to an F_Port on a switched fabric or
directly to another N_Port (in point-to-point communications).
