converged network adapter (CNA)

Converged NetworkAdapters (CNA) are converging network adapters that are used to connect storage

area networks (SAN) with local area networks (LAN). Conceptually, it

is anetwork interface card (NIC) with a host bus adapter (HBA) for Fibre Channel (FC) and for Ethernet and TCP/IP. It connects via a dedicated 10 Gbps switch that supports both Converged Enhanced Ethernet (CEE) and Fibre Channel over Ethernet (FCoE). The LAN and Fibre Channel traffic can be transmitted over an optical fiber between the adapter and the switch

.

Converged Network Adapters (CNA) are used in Fibre Channel over Ethernet (FCoE) and have the advantage that the server only needs to be equipped with a CNA card and thus has access to the local network and the storage network.
