port
Access points in a device where a link
attaches. There are four types of ports, as
follows:

N_Port —a Fibre Channel port that
supports point-to-point topology.
 NL_Port —a Fibre Channel port that
supports loop topology.
 F_Port —a port in a fabric where an
N_Port can attach.
 FL_Port —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 discovered
by the system.
POST
Power-on self test. Diagnostics that the
router performs at start-up.

RISC
Reduced instruction set computer. A
computer microprocessor that performs
fewer types of computer instructions,
thereby operating at higher speeds.
RPC
A protocol used by a program to request a
service from a program located in another
computer in a network. RPC uses the
client/server model.
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
application that provides a
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.
