Intel has just released source code for Fibre Channel over Ethernet (FCoE). It provides some Fibre Channel protocol processing as well as the encapsulation of FC frames within Ethernet packets. FCoE will allow systems with an Ethernet adapter and a Fibre Channel Forwarder to login to a Fibre Channel fabric (the FCF is a “gateway” that bridges the LAN and the SAN). That fabric login was previously reserved exclusively for Fibre Channel HBAs. This technology reduces complexity in the data center by aiding network convergence. It is targeted for 10Gps Ethernet NICs but will work on any Ethernet NIC supporting pause frames. Intel will provide a Fibre Channel protocol processing module as well as an Ethernet based transport module. The Open-FC module acts as a LLD for SCSI and the Open-FCoE transport uses net_device to send and receive packets.
This is good news. I think one can compare bandwidth and throughput for copper and fiber Ethernet. If you are going to use copper you need to stay within 15m of the switch. This solution will try to bring down cost. One can connect to 8-10 server to central database server with 10G and there could be few more applications.
