Scenario B: Isolated engine tier and parallel engine configuration
Scenario B is an installation with a computer that is dedicated to the IBM® InfoSphere® Information Server engine.
The retail chain that built the Scenario A development system also wants to build a larger production system. They are expecting a relatively high volume of job throughput. They decide to create a configuration in which the engine tier is built on a dedicated server (Host2 in the following diagram). To provide additional capacity, they set up a separate computer (Host3) to serve as a parallel processing compute node. The repository tier and services tier share a server (Host1).
