Route
As applies to a fabric, the communication path between two switches. May also apply to the
specific path taken by an individual frame, from source to destination.
Routing
The assignment of frames to specific switch ports, according to frame destination.
RR_TOV
Resource Recovery Time-out Value; the minimum time a target device in a loop waits after a
LIP before logging out a SCSI initiator.
RSCN
Registered State Change Notification; a switch function that allows notification of fabric
changes to be sent from the switch to specified nodes.
RX_ID
Responder Exchange Identifier. A 2-byte field in the frame header used by the responder of
the Exchange to identify frames as being part of a particular exchange.
SAN
Storage Area Network; a network of systems and storage devices that communicate using
Fibre Channel protocols. See also Fabric.
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 of 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-level functions, or TCP/IP for both. Can be
made available over other protocols, such as UDP/IP, because it does not rely on the
underlying communication protocols.
Switch Name
The arbitrary name assigned to a switch.
Switch Port
A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
