public loop
An arbitrated loop that includes a participating FL_Port and
may contain both public and private NL_Ports. See also
.
public NL_Port
An NL_Port that logs in to the fabric, can function within a
public or private loop, and can communicate with private or
public NL_Ports. See also
quad
A group of four adjacent ports that share a common pool of
frame buffers.
R_A_TOV
Resource allocation time-out value. The maximum time a frame
can be delayed in the fabric and still be delivered.
route
With respect 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 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.
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
SAN Switch installation guide
