DLS
Dynamic load sharing. Dynamic distribution of traf
fi
c over available paths.
Allows for recomputing of routes when an Fx_Port or E_Port changes status.
domain ID
Unique identi
fi
er 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 de
fi
ned 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.

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
con
fi
guration
The currently enabled con
fi
guration of zones. Only one con
fi
guration can be
enabled at a time.

fl
ow
control
A facility that governs
fl
ow 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.

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 identi
fi
er 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 Con
fi
guration Server switch. One or more designated HP switches that
store and manage the con
fi
guration and security parameters for all switches
in the fabric.
Fibre Channel
The primary protocol for building SANs to transmit data between servers,
switches, and storage devices. Unlike IP and Ethernet, Fibre Channel is
designed to support the needs of storage devices of all types. It is a high-speed,
serial, bidirectional, topology-independent protocol, and is a highly scalable
interconnection between computers, peripherals, and networks.
fi
ll word
An IDLE or ARB ordered set that is transmitted during breaks between data
frames to keep the link active.
