Applications
PCI-E NIC Cards provide redundant connectivity to ensure an uninterrupted network connection.
PCI-E NIC Cards are ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs.
They are specially designed for desktop PC clients, servers, and workstations with few PCI Express slots available.

What is a Converged Network Adapter?
A converged network adapter (CNA) is a single network interface card (NIC) that contains both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet NIC. It connects servers to FC-based storage area networks (SANs) and Ethernet-based local area networks (LANs).
The CNA connects to the server via a PCI Express (PCIe) interface. The server sends both FC SAN and LAN and traffic to an Ethernet port on a converged switch using the Fibre Channel over Ethernet (FCoE) protocol for the FC SAN data and the Ethernet protocol for LAN data. The converged switch converts the FCoE traffic to FC and sends it to the FC SAN. The Ethernet traffic is sent directly to the LAN.
In networks without CNAs, servers have to have at least two adapters: One with a FC HBA to connect the server to the storage network, and another with a TCP/IP Ethernet NIC to connect the server to the LAN.
Using a single CNA to connect servers to storage and networks reduces costs by requiring fewer adapter cards, cables, switch ports, and PCIe slots. CNAs also reduce the complexity of administration because there is only one connection and cable to manage.
