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. Thus 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.

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.
router log
Log of messages describing events that
occur on the intelligent storage router.
RPC
Remote procedure call. 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 mode.
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.
SAN
Storage area network. Multiple storage
units (disk drives) and servers connected
by networking topology.
SANsurfer Router Manager
Also called iSCSI/FC Router Manager.
Workstation-based router management
application that provides a graphical user
interface (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.
SFP
Small form-factor pluggable. A transceiver
device, smaller than a GigaBit Interface
Converter, that plugs into the Fibre
Channel port.
