Fibre Channel started in 1988, with ANSI standard approval in 1994, to merge the benefits of multiple physical layer implementations including SCSI, HIPPI and ESCON. Fibre Channel was designed as a serial interface to overcome limitations of the SCSI and HIPPI physical-layer parallel-signal copper wire interfaces.
All Fibre Channel communication is done in units of four 10-bit codes. This group of 4 codes is called a transmission word . An ordered set is a transmission word that includes some combination of control (K) codes and data (D) codes .
Fibre Channel consists of the following layers: FC-0 -- The interface to the physical media; FC-1 -- The encoding and decoding of data and out-of-band physical link control information for transmission over the physical media; FC-2 -- The transfer of frames, sequences and exchanges comprising protocol information units.
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium.
The Fibre Channel FC1 data link layer is then responsible for implementing the 8b/10b encoding and decoding of signals. The Fibre Channel 8b/10b coding scheme is also used in other telecommunications systems. Data is expanded using an algorithm that creates one of two possible 10-bit output values for each input 8-bit value.
Fibre Channel is a layered technology that starts at the physical layer and progresses through the protocols to the upper-level protocols like SCSI and SBCCS. The serialized Small Computer Systems Interface (SCSI) protocol is often used on top of the Fibre Channel switched fabric protocol in servers and SAN storage devices.
Mapping between Fibre Channel N_port IDs (aka FCIDs) and Ethernet MAC addresses. "Converged" network adapter. Computers can connect to FCoE with converged network adapters (CNAs), which contain both Fibre Channel host bus adapter (HBA) and Ethernet network interface controller (NIC) functionality on the same physical card. CNAs have one or more ...
FICON (Fibre Connection) is the IBM proprietary name for the ANSI FC-SB-3 Single-Byte Command Code Sets-3 Mapping Protocol for Fibre Channel (FC) protocol.It is a FC layer 4 protocol used to map both IBM's antecedent (either ESCON or parallel Bus and Tag) channel-to-control-unit cabling infrastructure and protocol onto standard FC services and infrastructure.
