a. A Gen2 PCIe slot is required to provide the bandwidth for all four ports to operate at full speed.
b. Use within IBM i it is not supported. Instead, use it with the Virtual I/O server.
Note: The usage of NPIV through the Virtual I/O server requires a NPIV-capable Fibre
Channel adapter such as the FC 5729, FC 5735, FC 5273, FC EN0A, and FC EN0B.

2.7.9 Fibre Channel over Ethernet

Fibre Channel over Ethernet (FCoE) allows for the convergence of Fibre Channel and
Ethernet traffic onto a single adapter and converged fabric.
Figure 2-17 compares existing Fibre Channel and network connections and FCoE
connections.

Table 2-18 lists available Fibre Channel over Ethernet adapters. They are high-performance
Converged Network Adapters (CNA) using SR optics. Each port can provide Network
Interface Card (NIC) traffic and Fibre Channel functions simultaneously.
