Domain ID As applies to SilkWorm switches, a unique number between 1 and 239 that
identifies the switch to the fabric and is used in routing frames. Usually
automatically assigned by the switch, but can be manually assigned.
E_D_TOV
Error Detect Time-out Value; the minimum amount of 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. See also R_A_TOV, RR_TOV.
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.
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 2 services to manage the exchange of
frames across the fabric between source and destination. See also End-to-end
Flow Control, BB_Credit.
EIA Rack A storage rack that meets the standards set by the Electronics Industry
Association.
Enabled Zone
Configuration
The currently enabled configuration of zones. Only one configuration can be
enabled at a time. See also Defined Configuration, Zone Configuration.
End-to-end
Flow Control
Governs flow of class 1 and 2 frames between N_Ports. See also EE_Credit.
Error
As applies to fibre channel, a missing or corrupted frame, time-out, loss of
synchronization, or loss of signal (link errors). See also Loop Failure.
Exchange The highest level fibre channel mechanism used for communication between
N_Ports. Composed of one or more related sequences, and can work in either 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 FL_Port, Fx_Port.
Fabric A fibre channel network containing two or more switches in addition to hosts and
devices. May also be referred to as a switched fabric. See also Topology, SAN,
Cascade.
Fabric Name
The unique identifier assigned to a fabric and communicated during login and
port discovery.
Fabric OS TM The proprietary operating system on Brocade switches.
FC-AL-3
The Fibre Channel Arbitrated Loop standard defined by ANSI. Defined on top of
the FC-PH standards.
FC-FLA The Fibre Channel Fabric Loop Attach standard defined by ANSI.
FCP Fibre Channel Protocol; mapping of protocols onto the fibre channel standard
protocols. For example, SCSI FCP maps SCSI-3 onto fibre channel.
FC-PH-1, 2, 3
The Fibre Channel Physical and Signalling Interface standards defined by ANSI.
FC-PI The Fibre Channel Physical Interface standard defined by ANSI.
FC-PLDA
The Fibre Channel Private Loop Direct Attach standard defined by ANSI. Applies
to the operation of peripheral devices on a private loop.
