Converged network adapters (CNAs) - server cards that pass multiple networking protocols over Ethernet cables – can offer a solution to virtual networking problems, it has been claimed.
Writing for Search Server Virtualization, Greg Shield said that for organisations looking to simplify their physical and virtual networking, these devices are "hard to ignore".
He explained that a CNA contains both a Fibre Channel Host Bus Adapter and a standard Ethernet NIC.
"The CNA portion that faces the outside world looks like a traditional NIC with one or two RJ45 Ethernet ports for Cat 5e or Cat 6 cables," Mr Shields stated.
"Once connected and properly routed, the CNA then passes traditional TCP/IP networking as well as storage traffic."
He added that the CNA can pass both types of traffic at the same time, with the CNA-equipped virtual host seeing only routed network connections.
But for converged network adapters to function, the network must support an array of new Ethernet extensions for Fibre Channel over Ethernet, Mr Shields said.
"Because CNAs run both TCP/IP and storage traffic simultaneously, the entire network generally requires the added extensions," he noted.
