data word A type of transmission word that occurs within frames. The frame header, data
field, and CRC all consist of data words.
defined zone The set of all zone objects defined in the fabric. May include multiple zone
configuration configurations. See also zone,
directory service See SNS.
DLS Dynamic load sharing. Dynamic distribution of traffic over available paths. Allows
for recomputing of routes when an Fx_Port or E_Port changes status.
domain ID Unique identifier used in routing frames for all switches in a fabric. Usually
assigned by the principal switch, but can be assigned manually. The domain ID
for an HP switch can be any integer between 1 and 239. The default domain
ID is usually 1.
E_D_TOV Error-detect time-out value. The minimum time a target waits for a sequence to
complete before initiating recovery. Can also be defined as the maximum time
allowed for a round-trip transmission before an error condition is declared.
E_Port Expansion port. A type of switch port that can be connected to an E_Port on
another switch to create an ISL. See also
EE_Credit End-to-end credit. The number of receive buffers allocated by a recipient port to
an originating port. Used by Class 1 and Class 2 services to manage the
exchange of frames across the fabric between source and destination.
EIA rack A storage rack that meets the standards set by the Electronics Industry Association
(EIA).
enabled zone The currently enabled configuration of zones. Only one configuration can be
configuration enabled at a time. See also zone,
end-to-end flow A facility that governs flow of class 1 and class 2 frames between N_Ports.
control
error With respect to FC, a missing or corrupted frame, time-out, loss of
synchronization, or loss of signal (link error).
exchange The highest-level FC mechanism used for communication between N_Ports.
Composed of one or more related sequences; can work in one or both directions.
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface
over links. Can be used to connect an N_Port to a switch. See also U_Port.
fabric An FC network containing two or more switches in addition to hosts and devices.
May also be called a switched fabric.
fabric name The unique identifier assigned to a fabric and communicated during login and
port discovery.
FCIA Fibre Channel Industry Association. An international organization of FC industry
professionals. Among other things, provides oversight of ANSI and industry
standards.
FCP Fibre Channel Protocol. Mapping of protocols onto the FC standard protocols.
For example, SCSI FCP maps SCSI-3 onto FC.
