Fibre Channel provides a secure, bi-directional, physical or logical point-to-point, low latency connection between two devices at a time. Like other serial interfaces such as Serial Attached SCSI (SAS), in Fibre Channel data is transmitted over the physical medium in serial fashion as opposed to parallel methods, which are used in SCSI and ATA physical interfaces. Serial transmission enables much longer connection distances as compared to parallel transmission methods, because far fewer signal lines are required, thereby reducing noise created by multiple signal lines all switching at the same time (cross talk).

A primary use for Fibre Channel is in the transport of block oriented storage traffic in SAN (Storage Area Network) applications. There are also specialized upper layer Fibre Channel protocols that are used in Defense and Avionics applications, to transport video streams for heads-up displays, for example.

Fibre Channel is designed to work with either optical fiber physical medium or copper cables in many connector and cable type configurations. Copper cables are relatively inexpensive, but they are useable only for shorter distances, in the range of 5-meters at 16GbFC and 3-meters at 32GbFC. In general, the higher the transmission speed, the shorter the distance that can be reliably supported by copper cable technology. A variety of copper solutions are available, the most commonly used being Direct Attach Copper (DAC) cabling in both SFP (Small Form-factor Pluggable) and QSFP (Quad Small Form-factor Pluggable) configurations. SFP and QSFP optical cabling solutions are also available, supporting reliable transmission distances greater than 10 meters, up to about 10 kilometers.

Architecture

Fibre Channel is a layered protocol, and is modeled loosely on the OSI model for networks. In the OSI model, and in the case of Fibre Channel, each layer provides specific services and makes the results available to the next layer.  Figure 1 below compares the defined OSI layer to the defined Fibre Channel layers.

Figure 1, OSI Model and Fibre Channel Network Layers

The layers in the table represent different functions and services that exist within the Fibre channel protocol definition. As with the other communication standards, protocol level analysis is often focused at the link layer (FC-2) and above.

Fibre Channel, like any network architecture, transports blocks of application information, called data payloads. Before sending a payload over the physical link, additional Fibre Channel specific control bytes are added to both the start and the end of the payload data. The combination of the control bytes and the payload data is called a frame, which is the basic unit of information in Fibre Channel.

Fibre Channel transfers data through switched or direct point-to-point connections which work by creating session specific connections between the source and destination devices. These connections last only until the transfer is completed and can be temporarily preempted by higher priority transfer requests.

Connections are made on Fibre Channel systems through “interconnect components” such as switches, hubs, and bridges. The ability of Fibre Channel to use different interconnect devices makes it flexible and scalable depending on user needs. A fully switched Fibre Channel network is called a Fabric topology. Fabric topology permits multiple alternative paths to be established between any two ports in the Fabric.

Summary

ibre Channel protocol is designed to support very low latency and high data transfer rates. The currently approved standard supporting up to 32Gb/S is generally referred to as 32GFC. Server virtualization and storage virtualization are broad trends that are driving the need for higher bandwidth. The need for high bandwidth in the network infrastructure is just now beginning to drive the replacement of previous product generations of 4,8 and 16GFC by 32GFC and soon, 64GFC.

Fibre Channel is a good choice for any environment with many servers needing lossless access to centralized storage, computer data centers for example. Because of this, Fiber Channel enjoys over 80% market share as the network interface used in external storage systems such as SAN environments.

Flexibility to Meet Any Debug Challenge

The SierraNet M648 hardware platform and graphical user interface provides the highest level of performance and flexibility available in the market for legacy and todays’ emerging high-speed network and fabric deployments.

The SierraNet M648 provides ultimate flexibility in analysis and verification of traditional or converged Ethernet and Fibre Channel products in a single platform and the flexibility to add protocol specific features, functionality, and speed support at the time of purchase or later by the addition of license keys.

Each FlexPort SFP28 pair can probe both Ethernet and Fibre Channel links of speeds up to 50Gbps/link for Ethernet and/or 64G FC/link on copper or optical cabling and eliminates the need for separate "single function" blades, pods, or adapters found in some competitive products providing a highly compact, extremely flexible, multi-function protocol analyzer.

The SFP28 pairs may be aggregated to support 100Gbps Ethernet links, and the integrated QSFP-DD connections support all Ethernet rates – 50GbE, 100GbE and 200GbE link traffic – for both analysis and jamming applications.

In addition to FlexPort technology, the SierraNet M648's sophisticated analysis and jamming software, the Net Protocol Suite, provides unmatched flexibility with customized data displays that easily identify and navigate to specific events of interest quickly. Decoding in the Net Protocol Suite's multiple trace views provide superior visibility for troubleshooting low level to application layer issues, decode per the supported specifications and their associated encoding schemes, and the zero-time search and filter capabilities easily find Ethernet and Fibre Channel events in a contextual and intuitive way. In a multi-protocol environment, Teledyne LeCroy's CrossSync™ can synchronize and correlate traces with our other leading protocol analysis tools, such as the PCI Express Summit analyzers, to understand how traffic, stimulus, and/or errors propagate across bridges or adapters.
