Notes, Cautions, And Warnings; Key Terms - Brocade Communications Systems Gateway Administrator's Manual

For readability, command names in the narrative portions of this guide are presented in mixed
lettercase: for example, switchShow. In actual examples, command lettercase is often all
lowercase. Otherwise, this manual specifically notes those cases in which a command is case
sensitive. The ficonCupSet and ficonCupShow commands are an exception to this convention.

network) deployment complexity by leveraging NPIV (N_Port ID virtualization).
Fabric switch that connects host, storage, or other devices, such as Brocade
Access Gateway, to the fabric.
N_Port ID virtualization. Allows a single Fibre Channel port to appear as
multiple, distinct ports providing separate port identification and security
zoning within the fabric for each operating system image as if each operating
system image had its own unique physical port.
An ISL (Interswitch link) port. A switch port that connects switches together to
form a fabric.
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 only.
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.
