Fibre Channel was originally conceived as
a single, high-bandwidth, multi-protocol data transport that could
meet a variety of data communications needs. It offers gigabit and
even multi-gigabit per second data throughput, supports multiple
network topologies, and is highly scalable to a variety of
connection requirements. Over time, it has become widely regarded
as the optimal data communications solution for storage
environments due to its high-bandwidth, flexibility and
reliability. However, when it comes to high-throughput,
peer-to-peer data transfers, a great deal of Fibre Channel’s
efficiency is sacrificed in order to utilize the TCP/IP protocol
stack. Various approaches have been developed to overcome the
throughput restrictions encountered when using Internet Protocol
(IP) over Fibre Channel, with the most promising being a
streamlined lightweight protocol that bypasses the protocol stack
and optimizes the peer-to-peer communication link.
