What protocol does Fibre Channel use?

Fibre channel basics:

A high-speed network technology called fibre channel is used to link servers to data storage area networks. It controls high-performance disc storage for applications across many corporate networks. Data backup and replication are provided.

The topologies that give the fibre channel flexibility are as follows:

Topology of points to points.

Arbitrated fibre channel loop.

changed the fabric topology.

Fibre Channel is necessary because it is very adaptable and enables faster data transmission.

An underlying Fibre Channel connection is used by the SCSI interface protocol known as Fibre Channel Protocol (FCP). The Fibre Channel standards provide a high-speed data transfer technique that may be used to connect workstations, mainframes, supercomputers, storage systems, and displays. A single standard is provided for networking, storage, and data transfer, FCP solves the demand for extremely quick transfers of massive amounts of data and may free system manufacturers from the difficulty of supporting a variety of channels and networks. Several Fibre Channel traits include:

1. from 266 megabits per second to 16 gigabits per second in performance

2. Support optical and copper media at up to 10 kilometer distances.

3. Small connectors (the most popular being sfp+)

4. High-bandwidth use with insensitivity to distance

5. From modest systems to supercomputers, support for various cost/performance levels

6. being able to transport many existing interface command sets, including audio/video, SCSI, IPI, HIPPI-FP, and Internet Protocol (IP).

Layers of a fibre channel include the following:

1. FC-0 — The physical media interface

2. Data and out-of-band physical link control information encoding and decoding for transmission via physical media is covered by FC-1.

3. Transfer of frames, sequences, and exchanges that make up protocol information units is referred to as FC-2.

4. FC-3: Common services needed for multicast, hunt groups, and advanced features like striping.

5. FC-4 — Fibre Channel-capable application interfaces, such as the Fibre Channel Protocol for SCSI (FCS).
