Introduction
This chapter describes the contents, intended audience, and organization of the
Intel
®
Adapter Hardware Installation Guide
.
The
Intel
®
Adapter Hardware Installation Guide
contains instructions for installing the
adapters. The following adapters are covered in this guide:
• QLE7340 PCI Express
• QLE7342 PCI Express
1.1
Intended Audience
This installation guide is intended for administrators responsible for installing the Intel
®
QLE7340 or QLE7342 adapter in their Linux
*
cluster. Additional detailed information
and instructions for administering an Intel
®
cluster can be found in the
Intel
®
OFED+
Host Software User Guide
.
The
Intel
®
Adapter Hardware Installation Guide
assumes that you are familiar with the
specific hardware that you plan to use. Before installing the adapter, you should have
basic knowledge of your host and target operating systems.
This document does not contain all the information you need to use basic Linux
*
commands or to perform all system administration tasks. For this information, see the
software documentation you received with your system.
1.2
How this Guide is Organized

software, describes interoperability with other products, lists all related
documentation, and provides Intel contact information.
•
Chapter 2.0, “Hardware Installation Checklist”
, provides a high-level overview of

Overview
The material in this documentation pertains to an OFED+
cluster
. A cluster is defined as
a collection of nodes, each attached to an InfiniBand
*
-based fabric through the Intel
®
interconnect. The nodes are generally Linux
*
-based computers having multiple
processors/cores.
The Intel
®
adapters are InfiniBand
*
4X. The Quad Data Rate (QDR) QLE7340 and
QLE7342 adapters have a raw data rate of 40Gbps.
The Intel
®
adapters utilize Intel
®
True Scale Fabric switches and cabling. The Intel
interconnect is designed to work with all InfiniBand
*
-compliant switches.
Note:
If you are using the QLE7340 or QLE7342, and want to use QDR mode, then QDR-
capable switches must be used.
Intel
®
OFED+ Host Software is interoperable with other vendors’ host channel adapters
running compatible OFED+ releases. There are several options for subnet management
in your cluster:
