Configuring Fibre Channel over
Ethernet 6
To access Fibre Channel storage, an ESXi host can use the Fibre Channel over Ethernet (FCoE)
protocol.
The FCoE protocol encapsulates Fibre Channel frames into Ethernet frames. As a result, your host does
not need special Fibre Channel links to connect to Fibre Channel storage. The host can use 10 Gbit
lossless Ethernet to deliver Fibre Channel traffic.

Fibre Channel over Ethernet Adapters
To use Fibre Channel over Ethernet (FCoE), configure appropriate adapters on your host.
The adapters that VMware supports generally fall into two categories, hardware FCoE adapters and
software FCoE adapters that use the native FCoE stack in ESXi.
For information on adapters that can be used with VMware FCoE, see the VMware Compatibility Guide
Hardware FCoE Adapters
This category includes a specialized offloaded Converged Network Adapters (CNAs) that contain network
and Fibre Channel functionalities on the same card.
When such adapter is installed, your host detects and can use both CNA components. In the
vSphere Client, the networking component appears as a standard network adapter (vmnic) and the Fibre
Channel component as a FCoE adapter (vmhba). You do not need to configure the hardware FCoE
adapter to use it.
Software FCoE Adapters
A software FCoE adapter uses the native FCoE protocol stack in ESXi to perform some of the FCoE
processing. You must use the software FCoE adapter with a compatible NIC.
