Fabric
The FC topology that is similar to a telephone switch in that the initiator of a “call” to
the receiving port simply provides the receiver with the port address, and the fabric
routes the transmission to the proper port. A fabric differs from a point-to-point or
arbitrated loop topology in that it provides for interconnections between ports
without having a point-to-point connection. The fabric also serves as a media type
converter.
FACT
Fabric active alias_ID.
FAN
Fabric address notification.
Fault Symptom Code
Four hexadecimal digits that identify a cartridge subsystem error.
FC
Fibre Channel.
FC_AL
Fibre Channel Arbitrated Loop standard.
FC-PH-1
The FC Physical and Signaling Interface defined in the ANSI X3.230-1994.
FC-PH-2
An extension of the FC Physical and Signaling Interface defined in the ANSI X3.230-
1994 that specifies several extra protocol levels.
FC-0
The level of the FC-PH-1 Standard that defines the physical level. FC-0 defines the
media types and connectors, as well as the electrical and optical characteristics,
necessary for connecting ports. This level can be found in the FC-PH-1 Standard,
clauses 5 to 10, and 12 to 15.
FC-1
The level of the FC-PH-1 Standard that defines the transmission protocol. FC-1
includes the 8B/10B encoding/decoding scheme, word order transmission, and error
detection. This level can be found in the FC-PH-1 Standard, clauses 11, 16, and 17.
FC-2
The level of the FC-PH-1 Standard that defines the framing and signaling protocol.
FC-2 includes the frame layout, frame header content, and rules for use. This level
can be found in the FC-PH-1 Standard, clauses 18 to 29.
FC-3
The level of the FC-PH-1 Standard that defines the common services level that may
be available across multiple ports in a node. This level has no current standard in the
FC-PH-1 Standard.
FC-4
The level of the FC-PH-1 Standard that defines the mapping of protocols between the
lower levels of FC, and the command sets that use FC. Separate standards exist for
SCSI-3, IP, IPI-3, HIPPI, and others.
FCP
See Fibre Channel Protocol.
