AS/400 IBM Network Station: Techniques for Deployment in a WAN
Figure 9. Network Station Implementation
The best place to start the discussion on these options is at the bottom of
Figure 9. In this scenario, there are 50 users in a stand-alone organization,
which has it’s own I/T function. This is the simplest setup and easiest to
compare with an existing NPT network. All information is stored on the local
AS/400 system. Users have sign on capability to all other AS/400 systems in
the network. Maintenance of these users is performed locally. Customizing is
done in NVRAM, as the users are in easy reach of the IT function. However,
depending on how frequently user requirements or application access
change,s it is better to control configurations centrally. Plan this as though it
were a system replacement. Performance must be considered if the
AS/400system is particularly small. If you are replacing workstations with
twinax attached network stations, do not use broadcast boot.
In the next scenario, there is a small group of 10 users attached to a central
system with no local server capability. This is an example of a potential Flash
card implementation. There are no local servers to hold boot information and
the number of users is small. Provided the users do not have huge Flash
memory requirements, Flash boot is a good choice. Ensure a duplicate Flash
card is sent to the site to reduce the impact of a primary card failure. If Flash
boot is not an option, consider the line speed and the installation of a local
