Views Read Edit View history. Servers may access storage from multiple storage devices over the network as well. Fibre Channelor FCis a high-speed data transfer protocol commonly running at 1, 2, 4, 8, 16, 32, and gigabit per second rates providing in-order, lossless [1] delivery of raw block data [2]primarily used to connect computer data storage to servers.

Fibre Channel – Wikipedia

Lossless delivery of raw data block is achieved based on a credit mechanism [1]. The Fibre Channel physical layer is based on lughtpulse connections that use fiber optics to copper between corresponding pluggable modules.

Individual variations for each specification are listed in the references associated with those entries in this table. If multiple switch vendors are used within the same fabric it is heterogeneousthe switches may only achieve adjacency if all switches are placed into their interoperability modes.


There are three major Fibre Channel topologies, describing how a number of ports are connected together.

Fibre Channel

However, running in native interoperability mode may still disable some proprietary features and can produce fabrics of questionable stability. Some are OS dependent. Most block storage runs over Fibre Channel Fabrics and supports many upper level protocols.

How to Find the HBA/Fibre Channel Cards, Ports and WWN in Linux – techbeatly

Commercial products were released while the standard was still in draft. By appealing to the large base of SCSI disk drives and leveraging mainframe technologies, Fibre Channel developed economies of scale for advanced technologies and deployments became economical and widespread. The most common types of ports are:.

Fibre Channel ports come in a variety lightpulde logical configurations. Some switch manufacturers offer a variety of interoperability modes above and beyond the “native” and “open fabric” states.

List of solid-state drive manufacturers. This is called the “open fabric” mode as each vendor’s switch may have to lightpules its proprietary features to comply with the Fibre Channel standard. The SAN is a dedicated network that enables multiple servers to access data from one or more storage devices.


Fibre Channel can be used to transport data from storage systems that use solid-state flash memory storage medium by transporting NVMe protocol commands. Two completely separate fabrics are operational and if the primary fabric fails, then the second fabric becomes the primary.

Fibre Channel has doubled in speed every few years since Fibre Channel switches can be divided into two classes. Retrieved from ” https: These classes are not part of the standard, and the classification of every switch is a marketing decision of livhtpulse manufacturer:.

Archived from the original on Fibre Channel networks form a switched fabric because they operate in unison as one big switch. FC was developed with leading edge multi-mode optical fiber technologies that overcame the speed limitations of the ESCON protocol. A fabric consisting entirely of one vendors products is considered to be homogeneous.

The quad small form-factor pluggable QSFP module began being used for switch inter-connectivity and was later adopted for use in 4-lane implementations of Gen 6 Fibre Channel supporting GFC. Retrieved June 28, SFP modules support a variety of distances via multi-mode and single-mode optical fiber as shown in the table below.
