AS/400 IBM Network Station: Techniques for Deployment in a WAN
Figure 32. Fully Centralized Configuration
The advantages for this strategy are:
• Centralized server management
• Centralized configuration for all clients
• Fewer servers to deploy and manage
• Reduced hardware costs (due to fewer servers)
However, there are several significant disadvantages:
• A very high bandwidth connection between the sites (T1 or better) is
needed.
• If the link goes down, the central site is unavailable.
• The time required to download the operating system to the Network
Station could be 10 to 20 minutes, even on a 56k line.
Although the above configuration may apply to some customers, it is not
common for a Network Station implementation. This is a common
configuration for NPTs connected to a mainframe. The main disadvantage of
the this scenario, is that if the link goes down, your remote sites are rendered
useless.
