initiator
A server or workstation on a Fibre Channel network that initiates communications with storage devices. See also
target .
insistent domain ID mode
Sets the domain ID of a switch as insistent, so that it remains the same over reboots, power cycles, failovers, and
fabric reconfigurations. interswitch link
See ISL .
IOCTL
I/O control.
IP
Internet Protocol. The addressing part of TCP.
ISL
Interswitch link. A Fibre Channel link from the E_Port of one switch to the E_Port of another. See also E_Port .
isolated E_Port
An E_Port that is online but not operational due to overlapping domain IDs or nonidentical parameters (such as
E_D_TOVs). See also E_Port .
IU
Information unit. A set of information as defined by either an upper-level process protocol definition or upper-level
protocol mapping.
JBOD
Just a bunch of disks. A number of disks connected in a single chassis to one or more controllers. See also RAID .
K28.5
A special 10-bit character that indicates the beginning of a transmission word that performs Fibre Channel control
and signaling functions. The first seven bits of the character are the comma pattern.
key
A string of data (usually a numeric value) shared between two entities and used to control a cryptographic
algorithm. Usually selected from a large pool of possible keys to make unauthorized identification of the key
difficult. See also key pair .
key pair
In public key cryptography, a pair of keys consisting of an entity's public and private key. The public key can be
publicized, but the private key must be kept secret. See also public key cryptography .
L_Port
Loop port. A node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop capabilities. An L_Port can be in
either fabric mode or loop mode.
LAN
Local area network. A network in which transmissions typically take place over less than 5 kilometers (3.4 miles).
