The time span that begins when a port wins arbitration in a loop and ends when the same port
returns to the monitoring state. Also called loop tenancy.
throughput
The rate of data flow achieved within a cable, link, or system. Usually measured in bits per
second.
topology
With respect to FC, the configuration of the FC network and the resulting communication paths
allowed. There are three possible topologies:
•
Point-to-point: A direct link between two communication ports
•
Switched fabric: Multiple N_Ports linked to a switch by F_Ports
•
Arbitrated loop: Multiple NL_Ports connected in a loop

W

function and stored on the switch.

A computer used to access and manage the fabric. May also be called a management station
or host.
WWN
World wide name. An identifier that is unique worldwide. Each entity in a fabric has a distinct
WWN.
Z
