QuickLoop Implementation

Terminology

20
QuickLoop is implemented by a combination of hardware and software
components, and requires no actions on the part of the user after it is
installed and configured. The hardware components are responsible for the
transport of frames among looplets and across switches, and the software
components are responsible for QuickLoop initialization and error
handling.
The terms and concepts introduced in this section are fundamental to
understanding the use of QuickLoop with switches.
Switch terminology
The following two port types are on host or storage devices, not on
switches.
N_port
(Node port) An equipment port that is not loop capable. Used to connect
the equipment to the fabric.
NL_port
An equipment port that is loop capable. Used to connect an equipment
port to the fabric in a loop configuration through the FL_Port on a
switch.
There are 8 or 16 physical ports on varying model switches; certain models
constrain the type of port the switch can support. Each port can be
independently configured as one of various types:
F_port
A fabric port that is not loop capable. Able to transmit under fabric
protocol, and interface over links. N_Ports on equipment connect to
F_Ports on switches.
FL_port
A fabric port on a switch that is loop capable. Used to connect loop
capable NL_Ports to the switch in a loop configuration.
