Fibre Channel is not the only SAN technology—“Fibre Channel” and “SAN” are not synonymous:
Other technologies besides Fibre Channel have been used—and continue to be used—to build SANs. Fibre Channel has been applied to other specialized applications, with implementations addressing the video/broadcast industry and the avionics industry.
Today, most SANs are built on Fibre Channel, and Fibre Channel is most commonly used to build SANs. That may not be the case tomorrow.
