Power On Self Test
.
Series of self-tests run after a switch is rebooted or reset
.
Private NL_Port
NL_Port that does not log into the fabric and communicates only with private
NL_Ports in same loop.
Private device
Device that supports arbitrated loop protocol and understands 8-bit
addresses, but cannot log into fabric.
Private loop
An arbitrated loop with no fibre channel attachment.
Protocol
A defined method and standards for communication.
Public NL_Port
NL_Port that logs into the fabric, can function within public or private loops,
and can communicate with public or private NL_Ports.
Public device
Device that supports arbitrated loop protocol, understands 8-bit addresses,
and can log into fabric.
Public loop
An arbitrated loop attached to a switch.
QuickLoop
Can indicate either the software product that allows private devices within
loops to communicate over the fabric with other devices, or the set of actual
devices or looplets connected in a loop by QuickLoop technology.
R_A_TOV
Resource Allocation Time-out Value. Maximum time a frame can be delayed
in the fabric and still be delivered. See also E_D_TOV.
RAID
Redundant Array of Independent Disks. Collection of disk drives that appear
as a single volume to the server, and are fault-tolerant through mirroring or
parity checking. See also JBOD.
Remote Switch
Software product that enables two switches to connect over an ATM
connection. Requires compatible fibre channel-to-ATM gateways. Can be up
to 10 km distance between each switch and respective gateway.
Route
As applies to fabric, a communication path between two switches. See also
FSPF.
RSCN
Registered State Change Notification. Switch function that sends notification
of fabric changes from the switch to specified nodes.
SAN
Storage Area Network. Network of systems and storage devices that usually
communicate using fibre channel protocols. See also Fabric.
