HP 5697-7483 manual Rscn, San, Sdram, Snmp, Sns, Swl

RSCN	Registered state change notification. A switch function that allows notification of
	fabric changes to be sent from the switch to the specified nodes.
SAN	Storage area network. A network of systems and storage devices that
	communicate using FC protocols.
SDRAM	Synchronous dynamic random access memory. The main memory for a switch.
	See also ???.
sequence	A group of related frames transmitted in the same direction between two
	N_ports.
service rate	The rate at which an entity can service requests.
single mode	The fiber optic cabling standard that corresponds to distances up to 10 km
	between devices.
SNMP	Simple Network Management Protocol. An Internet management protocol that
	uses either IP for network-level functions and UDP for transport functions, or
	TCP/IP for both. SNMP can be made available over other protocols (such as
	UDP/IP) because it does not rely on the underlying communication protocols.
	See also ???, ???.
SNS	Simple Name Server. A switch service that stores names, addresses, and
	attributes for up to 15 minutes, and provides them as required to other devices in
	the fabric. May also be referred to as a directory service.
switch	Hardware that routes frames according to FC protocol and is controlled by
	software.
switch port	A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
SWL	short-wavelength. A type of fiber optic cabling that is based on 850 mm lasers
	and supports link speeds up to 2 Gb/s. May also refer to the type of transceiver.
tenancy	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 (b/s).
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
transmission	A 10-bit character encoded according to the rules of the 8b/10b algorithm.
character
transmission word A group of transmission characters.
trap (SNMP)	The message sent by an SNMP agent to inform the SNMP management station
	of a critical error. See also ???.
U_Port	Universal port. A switch port that can operate as a G_Port, E_Port, F_Port, or
	FL_Port. A port is defined as a U_Port when it is not connected or has not yet
	assumed a specific function in the fabric. See also ???, ???, ???.
well-known	With respect to FC, a logical address defined by the FC standards as assigned
address	to a specific function and stored on the switch.
