Planning cluster network connectivity

Prerequisites

In the Initial cluster planning topic, you began planning your cluster, identifying the number of nodes and the key applications you want to make highly available. You started drawing the cluster diagram. This diagram is the starting point for the planning you will do in this section.

Also, by now you should have decided whether or not you will use IP address takeover (IPAT) to maintain specific service IP addresses.

Overview

Your primary goal is to use redundancy to design a cluster topology that eliminates network components as potential single points of failure.

The following table lists these network components with solutions:

In this section, you complete the following planning tasks:

• Designing the cluster network topology, that is, the combination of IP networks that connect your cluster nodes and the number of connections each node has to each network.
• Adding networking to your cluster diagram.
