6.2 Fibre Channel Overview
Fibre Channel supports multiple protocols over the same physical interface.
Fibre Channel is primarily a protocol-independent transport medium;
therefore, it is independent of the function for which you use it.
TruCluster Server uses the Fibre Channel Protocol (FCP) for SCSI to use
Fibre Channel as the physical interface.
Fibre Channel, with its serial transmission method, overcomes the
limitations of parallel SCSI by providing:
• Data rates of 100 MB/sec, 200 MB/sec, and 400 MB/sec
• Support for multiple protocols
• Better scalability
• Improved reliability, serviceability, and availability
Fibre Channel uses an extremely high-transmit clock frequency to achieve
the high data rate. Using optical fibre transmission lines allows the
high-frequency information to be sent up to 40 km, the maximum distance
between transmitter and receiver. Copper transmission lines may be used
for shorter distances.
