	connects to the PCI bus of the processor. Not visible within
	the processor’s memory space.
conﬁguration	The way a system is set up. May refer to hardware or software:
	• Hardware: The number, type, and arrangement of
	components that make up a system or network.
	• Software: The set of parameters that guide switch operation.
	May include general system parameters, IP address
	information, domain ID, and other information. Modiﬁable
	by any login with administrative privileges. May also refer
	to a set of zones.
CRC	Cyclic redundancy check. A check for transmission errors that
	is included in every data frame.
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 con- The set of all zone objects deﬁned in the fabric. May
ﬁguration	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 ISL
	trunking, 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 storage rack that meets the standards set by the Electronics
	Industry Association (EIA).
