Infiniband Host Channel Adapter - IBM Power System E850C Technical Overview And Introduction

Table 2-20 lists the available FCoE adapters. They are high-performance Converged Network
Adapters (CNAs) that use SR optics. Each port can simultaneously provide network interface
card (NIC) traffic and Fibre Channel functions.

Note: Adapters #EN0H, and #EN0K, support SR-IOV when minimum firmware and
software levels are met.

2.9.7 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 that are necessary for
present and future server systems with levels better than can be achieved by using
bus-oriented I/O structures.
InfiniBand is an open set of interconnect standards and specifications. The main InfiniBand
specification is published by the IBTA and is available at the following website:
http://www.infinibandta.org
InfiniBand is based on a switched fabric architecture of serial point-to-point links, where these
InfiniBand links can be connected to either host channel adapters (HCAs), which are used
primarily in servers, or target channel adapters (TCAs), which are 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 of 2.5 - 120 Gbps. The architecture defines a
layered hardware protocol and a software layer to manage initialization and the
communication between devices. Each link can support multiple transport services for
reliability and multiple prioritized virtual communication channels.
For more information about InfiniBand, see HPC Clusters Using InfiniBand on IBM Power
Systems Servers, SG24-7767.
A connection to supported InfiniBand switches is accomplished by using the QDR optical
cables #3290 and #3293.
