From an IT perspective, one centralized server has the advantages of:
* single point of maintenance, updates, system administration, and
operations
* No "field trips" troubleshooting remote problems (assuming you don't
staff each plant with IT people)
* No worries about synchronization of centralized data (remote systems
don't need to phone home periodically)
A few disadvantages:
* single point of failure should it go up in smoke (can be avoided by
mirroring/arrays, etc., which is easier to cost-justify for one
system than 6-8 separate sets of redundancy)
* Network WAN infrastructure is [more] critical to the satellite
plants, you would likely want a dedicated primary circuit with
something like an ISDN dial-on-demand backup
* Higher cost of software that may only be used by special groups as
it must be licensed for a higher tier
To eliminate the latter case, you may want to consider buying a small
machine (918 or similar) to use for developers and specialized apps.
Development tools are *expensive* on big machines.
