Planning the cluster

You can add Web servers to an existing cluster, use existing servers in a cluster as Web servers, or create a cluster for Web traffic only. You plan the cluster by considering the same factors you consider when you create any IBM® Lotus® Domino™ cluster. For example, you should consider the processing power of the servers available and how much traffic there will be in the cluster. If there is a lot of Web traffic on a server, you should consider dedicating the server to Web traffic only. You should also distribute databases in a way that balances the workload.

In general, you should consider the following factors:

• The number of servers to include in the cluster
• The number and placement of replicas in a cluster
• How to distribute databases across servers
• Whether to create a private LAN for cluster traffic
• Where to locate the ICM

Planning the location of the ICM

You can configure the ICM in several ways. For example you can:

• Configure a single ICM and place it outside the cluster
• Configure multiple ICMs outside the cluster
• Configure a single ICM as part of the cluster
• Configure multiple ICMs as part of the cluster
• Configure one ICM outside the cluster and one inside the cluster
