You can install platform agents on either:
A Sun Management Center server layer host
A Sun Management Center dedicated platform agent host
The number of platform agents that can be installed on a given host varies depending on whether that host is a Sun Management Center server layer or platform agent layer host. To maximize the overall performance and responsiveness of Sun Management Center, platform agents should be deployed on dedicated hosts instead of the server layer host. If the server layer is deployed on a multiple CPU system with excess capacity, you can consider running platform agents on a server layer host.
The following figure shows the architecture for a dedicated platform agent host deployment, and a server layer host deployment.
