How to Read This Document

This document is divided into three main sections. These sections have been designed to target

three specific audiences: the Executive, the first-time user, and the advanced user. While you

can skip to the section that is specific to your needs, it is recommended that you read all of the

sections in order, since some information is not repeated in every section.

Section Layout

Section 2: An executive overview of

teaming

Target audience: the Executive

The purpose of this section is to provide a high-level,

executive overview and introduction to HP Integrity

Network Adapter Teaming. The main purpose of this

section is to provide information to an Executive seeking

business justification for deploying HP Integrity Network

Adapter Teaming.

Section 3: Teaming fundamentals for

the first-time user

Target audience: Beginner to intermediate user

In this section, an intermediate introduction to HP Integrity

Network Adapter Teaming is provided for the first time

user/implementer. This section can also be used as a quick

reference section for the occasional user. A general

overview of the capabilities and options for HP Integrity

Network Adapter Teaming is provided.

Section 4: The mechanics of teaming

for the advanced user

Target audience: Intermediate to advanced user

This section provides detailed information about the

design, implementation, and configuration of HP Integrity

Network adapter teaming. The purpose of this section is

to assist networking specialists, systems engineers, and IM

professionals in the design and troubleshooting of

environments incorporating this technology in HP Integrity

servers. Topics for this section include advanced technical

discussions of all features, failure recovery methods, load

balancing logic, network scenario considerations, etc. You

should be familiar with the basics of IP communication

and addressing, the OSI model, the use of network drivers,

and the fundamentals of network switching. Additionally,

you should be familiar with the terms found in the glossary

of this white paper.
