IBM Power Systems E870 and E880 Technical Overview and Introduction
2.7.6 Fibre Channel over Ethernet
Fibre Channel over Ethernet (FCoE) allows for the convergence of Fibre Channel and
Ethernet traffic onto a single adapter and a converged fabric.
Figure 2-22 compares existing Fibre Channel and network connections and FCoE
connections.

connections
Table 2-26 lists the available FCoE adapters. They are high-performance Converged Network
Adapters (CNAs) using SR optics. Each port can simultaneously provide network interface
card (NIC) traffic and Fibre Channel functions.
Table 2-26 Available FCoE adapters
For more information about FCoE, see An Introduction to Fibre Channel over Ethernet, and
Fibre Channel over Convergence Enhanced Ethernet, REDP-4493.
2.7.7 Asynchronous and USB adapters
Asynchronous PCI adapters provide connection of asynchronous EIA-232 or RS-422
devices.
Each system control unit enclosure can have one slim-line bay which can support one DVD
drive (#EU13). The #EU13 DVD is cabled to a USB PCIe adapter located in either the system
node or in a PCIe Gen3 I/O drawer.
