All information in Fibre Channel is transmitted in groups of four transmission characters called transmission words. Some transmission words have K28.5 as the first transmission character. These are special transmission characters called ordered sets. Some ordered sets mark the beginnings and ends of frames (frame delimiters). Others convey information in between frames in the form of primitive signals (a single ordered set) and primitive sequences (a stream of the same ordered set). Examples of ordered sets are SOF, EOF, idle, receiver ready (R_RDY), LIP, ARB, OPN, CLS, and several others.

Fibre Channel defines a variable-length frame consisting of 36 bytes of overhead and up to 2,112 bytes of payload for a total maximum size of 2,148 bytes. The total size of the frame must be an even multiple of 4 bytes so that partial transmission words are not sent. Between 0 and 3 pad bytes are appended to the end of the payload to satisfy this rule. A SOF delimiter and EOF delimiter mark the beginning and end of each Fibre Channel frame. The CRC is the same 32-bit CRC used in FDDI.

A Fibre Channel sequence is a series of one or more related frames transmitted unidirectionally from one port to another. All frames must be part of a sequence. Frames within the same sequence have the same SEQ_ID field in the header. The SEQ_CNT field identifies individual frames within a sequence. For each frame transmitted in a sequence, SEQ_CNT is incremented by 1. This provides a means for the recipient to arrange the frames in the order in which they were transmitted and to verify that all expected frames have been received. Multiple sequences to multiple ports may be active at a time.

A Fibre Channel exchange is a series of one or more nonconcurrent sequences between two ports. The sequences may be in either direction. All sequences (and therefore all frames) must be part of an exchange. The originator of the exchange assigns the OX_ID field. The responder assigns the RX_ID field. As another perspective, one can use the following analogy: frame word sentence conversation
sequence exchange
Of course, one main difference is that a Fibre Channel device can speak more than one sentence and hold more than one conversation at a time. Information technology (IT) managers, system integrators, and Value Added Resellers (VARs) quickly discover that Fibre Channel is built on the concepts and protocols they know well. Fibre Channel delivers the same types of functions, only faster, easier, more scalable, and much more reliable than SCSI and legacy networks. Fibre Channel systems expand the flexibility of IT organizations with their inherent ability to run SCSI and IP protocols on the same network. These networks bring new levels of capability and perfor-

mance. Fibre Channel systems are built without restrictions. Virtually any topology that an IT organization requires is possible. The basic building blocks are point-to-point dedicated bandwidth, loopshared bandwidth, and switched-scaled bandwidth. Switches and hubs are stackable. Fibre Channel networks and storage are built from products that are very familiar to IT professionals. Fibre Channel is what has made SANs a reality, and future developments on the interface likely will bring more features and faster speeds.
Summary
Fibre Channel attempts to combine the benefits of channel and network technologies. A channel is a closed, direct, structured, and predictable mechanism for transmitting data between relatively few entities. Channels are used commonly to connect peripheral devices such as disk drives, printers, tape drives, and so on to workstations. Common channel protocols are SCSIs and HIPPIs. Fibre Channel is the preferred technology for transmitting data between computer devices at a rate of up to 1 Gbps (1 billion bits per second). It is especially suited for connecting computer servers to shared storage devices and for interconnecting storage controllers and drives. Fibre Channel hubs are used to connect nodes in a loop. Logically, a hub is similar to a Token Ring hub with ring in and ring out. Each port on a hub contains a PBC to automatically open and close the loop. Hubs support hot insertion and removal from the loop. Fibre Channel defines three topologies: point to point, arbitrated loop, and fabric. Before a loop is usable, it must be initialized so that each port obtains an AL_PA, a dynamically assigned value by which the ports communicate. It maps to the lowest byte of the native address identifiers (_ID and SI_ID). Although the AL_PA is 1 byte long, only 127 values are valid (neutral running disparity). If more than 127 devices are present on the loop, some will not be able to select an AL_PA and will be forced into nonparticipating mode. The concept of flow control deals with problems where devices receive frames faster than they can process them. When this
