Structured Format for Data Transmission
Data is sent over Fibre Channel cable in a structured format. The smallest
structure of data sent is called a frame. Addressing is done within the frame
header. Frames are not visible to the upper-level protocols and consist of the
following fields:
■ Start of Frame (SOF) - 4 bytes
■ Frame Header - 24 bytes
■ Data Payload - (0-2048) bytes
■ Cyclic Redundancy Check (CRC) - 4 bytes
