link A connection between ports on Fibre Channel devices. The link is a full duplex
connection to a fabric or a simplex connection between loop devices.
logon Also called login, it is a procedure whereby a user or network connection is
identified as being an authorized network user or participant.
loop See arbitrated loop .
loop ID Seven-bit values numbered contiguous from 0 to 126 decimal that represent the
127 valid AL_PA values on a loop (not all 256 hexadecimal values are allowed
as AL_PA values per Fibre Channel).
loop pair A Fibre Channel attachment between a controller and physical disk drives.
Physical disk drives connect to controllers through paired Fibre Channel arbitrated
loops. There are two loop pairs, designated loop pair 1 and loop pair 2. Each
loop pair consists of two loops (called loop A and loop B) that operate
independently during normal operation, but provide mutual backup in case one
loop fails.

) bytes per second.
