IBM Flex System V7000 Storage Node Introduction and Implementation Guide

In a traditional FC storage area network (SAN) and LAN environment, the server has an 
Ethernet adapter for data traffic and a Fibre Channel host bus adapter (HBA) for storage 
traffic. With converged networks which may include FCoE, these two adapters are replaced 
by a converged network adapter (CNA) that services both protocol stacks. A cable from the 
CNA connects to a lossless Ethernet switch, which eventually provides connectivity to an FCF 
and storage devices. Figure 11-10 on page 445 illustrates a CNA in an IBM Flex System 
Enterprise Chassis compute node server. In the compute node the only CNA adapter 
available is the IBM Flex System CN4054 10Gb Virtual Fabric Adapter.

Figure 11-10 on page 445 shows an example of FCoE connectivity of a compute node to the 
IBM Flex System V7000 Storage Node where the I/O module switch used is a IBM Flex 
System Fabric CN4093 10Gb Converged Scalable Switch, this provides both FCF and DCB 
functionality.
