6 Tivoli Provisioning Manager for OS Deployment in a Retail Environment
centrally located application server if the local application server fails. There are
many wariations possible, however, they are not the topic for this Redpaper.
It is important to note that most larger warehouses have a surplus of POS
systems which reduces the effects of one or a few systems being out of order.
Smaller stores or restaurants are more likely to be affected, even if one system is
out of order, since they may only have a total of two or three POS systems.
1.4 Operating systems on Point-of-sale devices
Not all operating systems are suitable for point-of-sales devices. A typical POS
system has a lot of special devices that require drivers which are not widely
available on all platforms. Also, the IT department may want to prevent the user
from getting access to anything but the POS application which require an
operating system with lockdown features.
The most common operating systems for point-of-sale systems include, but are
not limited to:
Microsoft® Windows® XP Professional
Microsoft Windows 2000 Workstation
WEPOS; Microsoft Windows Embedded for Point-of-services
IRES; IBM Retail Environment for Suse Linux for POS
Different distributions of Linux also exist.
Older environments may also include systems running PC-DOS 2000.
For the scenarios used throughout this Redpaper we will only use Windows XP.
For information about deploying Windows 2000 and Linux, please consult the
IBM RedBook Deployment Guide Series: Tivoli Provisioning Manager for OS
Deployment V5.1, SG24-7397.
