viii SUSE Linux Enterprise Point of Service Guide

Product Overview

SUSE® Linux Enterprise Point of Service is a secure and reliable Linux platform opti-

mized for enterprise retail organizations. Built on the solid foundation of SUSE® Linux

Enterprise, it is the only enterprise-class Linux operating system tailored specically

for retail Point of Service terminals, kiosks, self-service systems, and reverse-vending

systems.

This section provides an architectural overview of the SUSE Linux Enterprise Point of

Service product, along with an overview of server types, images, and the deployment

process.

1.1 Architecture

The SUSE Linux Enterprise Point of Service architecture consists of one centralized

Administration Server, one or more Branch Servers, and Point of Service terminals.

These can be standard PCs running retail check-out applications or specialized point-

of-sale machines such as cash registers and customer kiosks (see Figure 1.1, “SUSE

Linux Enterprise Point of Service System Architecture” (page 2)). Find a list of system

requirements for the individual components in Section 1.2, “System Requirements”

(page 3) and an overview of the different server types and their functions in Section 1.3,

“Server Types” (page 5).

Product Overview 1

Figure 1.1 SUSE Linux Enterprise Point of Service System Architecture

All system information (system structure, image information, the conguration and

deployment method for each Branch Server and Point of Service terminal, etc.) is stored

in an LDAP database on the Administration Server (which may be replicated on Branch

Servers). The Administration Server usually also holds the master repository for the

images required to boot and congure Point of Service terminals and provides the

utilities required to build those images.

NOTE: Creating a Dedicated Image Building Server

However, if you have a large system and want to ofoad the image building

function from the Administration Server, you can also set up a dedicated Image

Building Server. For more information, see Chapter 4, Setting Up the Adminis-

tration Server (page 35) or Chapter 5, Setting Up a Dedicated Image Building

Server (page 47).

Triggered by the possyncimages.pl script (see Section B.3.9, “possyncimages.pl”

(page 217), each Branch Server downloads the system information and images required

for its local Point of Service terminals from the Administration Server. The Point of

Service terminals, in turn, download their respective images from the Branch Server

when they boot.
