Remote Servers and Split Boot Servers
109
These functions are:
• Base code server
• Terminal-based configuration server
• Authentication and configuration server
The separation of server function in Release 3 allows you to use the split boot
feature if you have multiple servers in your organization. The reasons for
separating these functions can vary from site to site. The following items are
some reasons why you would separate these function:
• Server consolidation
You may want to consolidate all your user data and configuration files on
one server.
• Flash boot
Flash cards can only provide basic Boot services. As a result the user
authentication and configuration files have to be obtained from other
servers.
• Roaming
When you have mobile users, you have the ability for the user to logon with
his user-based terminal configuration at any location that supports
roaming.
• Load balancing
You may find that a segment or part of your network is not performing. To
improve performance you may want to add a server locally, but keep other
functions at another site.
4.4 Server Consolidation
In this scenario, we provide an example discussion with a common challenge,
server consolidation strategies after initial deployment of IBM Network
Stations. You may encounter this situation after deploying the IBM Network
Station across your network if your company decides to centralize computing
resources, hardware, personnel, and so on.
4.4.1 Scenario Objectives
The following objectives must be achieved to consolidate servers:
1. Start with a distributed configuration and move to a centralized one.
2. Change the authentication and configuration server.
