Glossary 58
defined zone
configuration
The set of all zone objects defined in the fabric. May include multiple zone
configurations. See also zone , zone configuration .
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 U_Port .
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 equipment storage rack that meets the standards set by the EIA (Electronics Industry
Association ).
enabled zone
configuration
The currently enabled configuration of zones. Only one configuration can be enabled
at a time. See also zone , zone configuration .
end-to-end flow
control
A facility that governs flow of class 1 and class 2 frames
between N_Ports.
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.
FCS switch Fabric Configuration Server switch. One or more designated HP switches that store and
manage the configuration and security parameters for all switches in the fabric.
