Glossary
16 Directors and Edge Switches Glossary
interoperability
Ability to communicate, execute programs, or transfer data between various functional units
over a network.
interoperability mode
(interop mode) — An operating mode, set through management software, that allows products
to operate in homogeneous or heterogeneous fabrics.
interswitch link
(ISL) — Physical expansion port (E_Port) connection between two directors in a fabric.
IOCDS
A data set that contains an I/O configuration definition built by the IOCP.
IOCP
See input/output configuration program.
IP address
See internet protocol address.
IPL
See initial program load.
ISL
See interswitch link.
jumper cable
Optical cable that provides physical attachment between two devices or between a device and a
distribution panel. See also trunk cable.
latency
The amount of time it takes for data transmission to pass through a switching device. When
used in reference to a Fibre Channel switching device, latency refers to the amount of time
elapsed between receipt of a data transmission at a switch’s incoming F_Port (from the
originating node port) to retransmission of that data at the switch’s outgoing F_Port (to the
destination N_Port).
LIN
See link incident.
link
Physical connection between two devices on a switched fabric.
link incident
(LIN) — Interruption to a Fibre Channel link due to loss of light or other causes.
