Installation Guide
ioctl
Input/output control. A system call in
UNIX
®
/Linux systems that allows an appli-
cation to control or communicate with a
device driver outside usual read/write
operations.
IP
Internet Protocol. A method by which data
is sent from one computer to another over
the Internet. IP specifies the format of
packets, also called
datagrams
, and the
addressing scheme.
iSCSI
Internet small computer system interface.
Protocol that encapsulates data into IP
packets to send over Ethernet connec-
tions.
iSNS
Internet simple name service (iSNS) is
used for discovery and management of
IP-based SANs.
L_Port
Loop port. Does arbitrated loop functions
and protocols. NL_Ports and FL_Ports are
examples of loop-capable ports. See
.
latency
A measure of how fast a transaction
travels through the router.
LED
Light emitting diode. Status indicator on a
switch or other device.
light emitting diode

LIP
Loop initialization process. The initializa-
tion process in an arbitrated loop that
occurs when the loop is powered up or a
new device is added. One function of a LIP
is to assign addresses. All data transmis-
sion on the loop is suspended during a LIP.
load balancing
A software feature that improves system
performance by balancing device access
between multiple ports for maximum
resource efficiency.
logical unit number

loopback
Diagnostic tool that routes transmit data
through a loopback connector back to the
same adapter.
LUN
Logical unit number, a subdivision of a
SCSI target. It is the small integer handle
that differentiates an individual disk drive
or partition (volume) within a common
SCSI target device such as a disk array.
Technically, a LUN can be a single
physical disk drive, multiple physical disk
drives, or a portion (volume) of a single
physical disk drive. However, LUNs are
typically not entire disk drives but rather
virtual partitions (volumes) of a RAID set.
Using LUNs, the Fibre Channel host can
address multiple peripheral devices that
may share a common controller.
maintenance button
Multifunction momentary switch on the
front panel of the router.
