CLUSTERS

Example of a single ICM outside the cluster
When you set up a single ICM outside the cluster, it is a good idea to dedicate the server to the ICM alone. The server should not contain any databases or server tasks other than those required to run the server. Configuring the ICM in this way makes it more reliable because there are fewer activities performed on the server that could interfere with performance and lead to server failure.

The following figure shows an HTTP client accessing a single ICM that resides outside the cluster. The ICM can redirect the client to any of the four Web servers in the cluster.
