2.8.9 Fibre Channel adapter
The IBM Power 770 and Power 780 servers support direct or SAN connection to devices that
use Fibre Channel adapters. Table 2-25 summarizes the available Fibre Channel adapters.
All of these adapters except #5735 have LC connectors. If you attach a device or switch with
an SC type fibre connector, an LC-SC 50 Micron Fiber Converter Cable (#2456) or an LC-SC
62.5 Micron Fiber Converter Cable (#2459) is required.

2.8.10 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 2-21 shows a comparison between an existing FC and network connection and a
FCoE connection.
