Ethernet is on a march to become the dominant interconnect for all types of network traffic.
Although Ethernet is the dominant interconnect for LANs (define), when it comes to storage and SANs (define), it lags other technologies, notably Fibre Channel (define). That's about to change.
Thanks to a new open source effort led by Intel, Fibre Channel over Ethernet (FCoE) technology is coming to Linux. FCoE may end up eliminating the gap between Fibre Channel and Ethernet providing users with more choice and flexibility in their networks.
