Ethernet is widely used in networking. With some advancement such as DCB and Priority Flow Control (PFC) in Ethernet to make it more reliable for the data center, FC is now also implemented on top of Ethernet. This implementation is known as FCoE.

In FCoE, fabric switches can be replaced with standard Ethernet switches, which are more cost effective. Also, the future development road map for Ethernet provides much higher speeds (40 Gbps and 100 Gbps) as compared to a native FC. There is rapid adoption of FCoE in the market and chances are that FCoE will completely replace the native FC implementation in the future.
