Figure 2-12 Comparison between existing Fibre Channel and network connection and FCoE connection
Table 2-18 lists the available Fibre Channel over Ethernet adapter. It is a high-performance
Converged Network Adapter (CNA) using SR optics. Each port can provide network interface
card (NIC) traffic and Fibre Channel functions simultaneously. NPIV support is available, but
requires VIOS for all operating systems.

2.7.11 InfiniBand host channel adapter

The InfiniBand architecture (IBA) is an industry-standard architecture for server I/O and
inter-server communication. It was developed by the InfiniBand Trade Association (IBTA) to
provide the levels of reliability, availability, performance, and scalability necessary for present
and future server systems with levels significantly better than can be achieved by using
bus-oriented I/O structures.
InfiniBand (IB) is an open set of interconnect standards and specifications. The main
IB specification is published by the InfiniBand Trade Association and is available at the
following location:
http://www.infinibandta.org/
InfiniBand is based on a switched fabric architecture of serial point-to-point links, where these
IB links can be connected to either host channel adapters (HCAs), used primarily in servers,
or to target channel adapters (TCAs), used primarily in storage subsystems.
The InfiniBand physical connection consists of multiple byte lanes. Each individual byte lane
is a four-wire, 2.5, 5.0, or 10.0 Gbps bidirectional connection. Combinations of link width and
byte-lane speed allow for overall link speeds from 2.5 Gbps to 120 Gbps. The architecture
