HP Brocade 8Gb SAN Switch for HP BladeSystem c-Class - Manual (Page 59)

multicast The transmission of data from a single source to multiple specified N_Ports (as
opposed to all ports on the network).
N_Port Node port. A port on a node that can connect to an FC port or to another N_Port
in a point-to-point connection.
name server A term frequently used to indicate a Simple Name Server (SNS). See also SNS .
NL_Port Node loop port. A node port that has arbitrated loop capabilities. Used to
connect an equipment port to the fabric in a loop configuration through an
FL_Port. See also
node .
node An FC device that contains an N_Port or NL_Port.
non-participating
mode A mode in which an L_Port in a loop is inactive and cannot arbitrate or send
frames, but can retransmit any received transmissions. This mode is entered if
there are more than 127 devices in a loop and an AL_PA cannot be acquired.
See also
L_Port , AL_PA .
Nx_Port A node port that can operate as an N_Port or NL_Port.
Onboard
Administrator (OA) The HP BladeSystem Onboard Administrator (OA) is the enclosure management
processor, subsystem, and firmware base used to support the HP BladeSystem
c7000 or HP BladeSystem c3000 and all the managed devices contained within
the enclosure.
packet A set of information transmitted across a network.
participating mode A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send
frames, and retransmit received transmissions.
path selection The selection of a transmission path through the fabric. HP switches use the FSPF
protocol for transmission path selection.
phantom address An AL_PA value assigned to a device that is not physically in the loop. Also
known as phantom AL_PA. See also
AL_PA , phantom device .
phantom device A device that is not physically in an arbitrated loop but is logically included
through the use of a phantom address. See also
phantom address .
PLOGI Port login. The port-to-port login process by which initiators establish sessions
with targets. See also
FLOGI .
point-to-point An FC topology that employs direct links between each pair of communicating
entities. See also
buffer-to-buffer flow control .
port cage The metal casing extending out of the FC port on the switch and into which a
GBIC or SFP transceiver can be inserted.
Port_Name The unique identifier assigned to an FC port. It is communicated during login
and port discovery.
POST Power-on self-test. A series of diagnostic tests run by a switch after it is powered
on.
primary FCS switch Primary Fabric Configuration Server switch. The switch that actively manages
the configuration and security parameters for all switches in the fabric.
