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
(iSR).
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 Router (iSR)s.
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.
