converged network adapter
Converged network adapter
From Wikipedia, the free encyclopedia
A converged network adapter (CNA), also called a converged network interface controller (C-NIC), is a computer input/output device that combines the functionality of a host bus adapter (HBA) with a network interface controller (NIC). In other words it "converges" access to, respectively, a storage area network and a general-purpose computer network.

Some products were marketed around 2005 with the term C-NIC which combined iSCSI storage functionality with Gigabit Ethernet. Later products used the marketing term converged network adapter (CNA), combining Fibre Channel over Ethernet with 10 Gigabit Ethernet, for example.
Brocade[edit]
Brocade Communications Systems offers two types of CNAs, with PCI Express generation 2.0 interfaces. The only difference between the two models are the number of interfaces on the cards: one or two. The two port model will allow connection to two different switches to create a redundant configuration without having to use two PCI slots.[1]
Broadcom[edit]
In 2009 Broadcom entered the CNA market. Broadcom offers their CNAs under their own brand name but also sell the application-specific integrated circuits and other related components to others. Their intended customers are the larger builders of server systems such as Dell and HP. These vendors can then include the ten Gigabit CNA with their servers: as embedded interface on the motherboard (LOM or LAN on Motherboard), via a mezzanine card in blade servers or as PCI extension-card.[2]
Emulex[edit]
Emulex offers CNAs under the Emulex brand name as the OneConnect ten Gigabit series of dual port optical and copper adapters. They also OEM their adapters for Cisco, Dell, EMC, Fujitsu, HDS, HP, IBM and NetApp.[3]
