[DC] FC / FCoE

FCoE is short for Fibre Channel over Ethernet.

Fibre Channel over Ethernet (FCoE) solves the problem of organizations having to run parallel network infrastructures for their local area networks (LANs) and their storage area networks (SANs). As a result, they have to operate separate switches, host bus adapters (HBAs), network interface cards (NICs) and cables for each of these networks. Even utilizing a virtualization solution like VMware can actually increase the number of network adapters required to carry traffic out of the servers.
