Glossary-4 SilkWorm 3800 Hardware Reference
enabled zone
configuration
The currently enabled configuration of zones. Only one configuration can be
enabled at a time. See also defined zone 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 cascade, SAN,
topology.
fabric name
The unique identifier assigned to a fabric and communicated during login and
port discovery.
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.
FCIA
Fibre Channel Industry Association. An international organization of fibre
channel industry professionals. Among other things, provides oversight of ANSI
and industry developed standards.
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.
FCS switch
Fabric configuration server switch. One or more designated SilkWorm switches
that store and manage the configuration and security parameters for all switches
in the fabric. FCS switches are designated by WWN, and the list of designated
switches is communicated fabric-wide. See also backup FCS switch, primary FCS
switch.
FC-SW-2
The second generation of the Fibre Channel Switch Fabric standard defined by
ANSI. Specifies tools and algorithms for the interconnection and initialization of
fibre channel switches in order to create a multi-switch fibre channel fabric.
fibre channel
transport
A protocol service that supports communication between fibre channel service
providers. See also FSP.
fill word
An IDLE or ARB ordered set that is transmitted during breaks between data
frames to keep the fibre channel link active.
firmware
The basic operating system provided with the hardware.
