It is likely to stay that way for the foreseeable future. Still, the various protocol innovations that have been developed in the pursuit of convergence – Fibre Channel over Ethernet (FCoE), 8G Fibre Channel, InfiniBand and Internet Small Computer Systems Interface (iSCSI), among them – stand to continue to play valuable roles in the storage and local area networks (SANs and LANs) of enterprises moving forward.
