FCP is a communication pattern which is different from traditional IP communication also engross line communication and is used to carry SCSI data through handshake pattern in SAN . On the other hand

the packet of FCP is not the invariable length packet but also different from the traditional variable length packet. Which fabric is the best one for the FCP communication? Through the research and compare the VOQ Crossbar

share memory and one of two dimensional fabric

the experiment result Showed that the two dimensional fabric has the better performance.
