Fibre Channel—a port in a fabric
where an N_Port can attach.
Fibre Channel—a port in a fabric
where an NL_Port can attach.
port instance
The number of the port in the system.
Each adapter may have one or multiple
ports, identified with regard to the adapter
as port 0, port 1 and so forth. To avoid
confusion when dealing with a system
containing numerous ports, each port is
assigned a port instance number when the
system boots up. So Port 0 on an adapter
might have a port instance number of 8,
for example, if it is the eighth port discov-
ered by the system.
POST
Power-on self test. Diagnostics that the
router performs at start-up.
reduced instruction set computer
See RISC.
registered state change notification
See RSCN.
RISC
Reduced instruction set computer. A
computer microprocessor that performs
fewer types of computer instructions,
thereby operating at higher speeds.
RSCN
Registered state change notification.
RSCN is a Fibre Channel fabric notification
sent to all specified nodes when any major
fabric changes occur. This notification
allows nodes to immediately gain knowl-
edge about the fabric and react accord-
ingly.
router log
Log of messages describing events that
occur on the Intelligent Storage Router.
SAN
Storage area network. Multiple storage
units (disk drives) and servers connected
by networking topology.
SANsurfer Router Manager
Workstation-based router management
utility that provides a graphical user inter-
face (GUI) used to configure and monitor
Intelligent Storage Routers.
SCSI
Small computer system interface. A
high-speed interface used to connect
devices, such as hard drives, CD drives,
printers, and scanners, to a computer. The
SCSI can connect many devices using a
single controller. Each device is accessed
by an individual identification number on
the SCSI controller bus.
Secure SHell
See SSH.
SFF
Small form factor. A transceiver device that
is permanently attached to the circuit
board.
SFP
Small form-factor pluggable. A transceiver
device, smaller than a GigaBit Interface
Converter, that plugs into the Fibre
Channel port.
simple network management protocol
See SNMP.
