Chapter 4Planning Your DeploymentThis chapter describes what you need to plan before starting the configuration stages and deploying the software load to a cluster. This chapter includes the following sections: Defining Your ClusterWhen choosing your hardware and software configuration, you must decide the following:
Planning Your ClusterYou must define your cluster hardware configuration before you start to configure your deployment environment. If you use an example hardware configuration, you can use the template files for configuring the cluster that are provided for that hardware configuration. For information about the example hardware configurations, see the Netra High Availability Suite Foundation Services 2.1 6/03 Hardware Guide. Planning Node GroupsNodes belonging to a node group share the following properties:
The node groups are defined so that groups of hardware can be configured to run particular services and applications. For example, you can define a node group for two master-eligible nodes called master_el, that can be configured to run a selection of Foundation Services. For information on how to configure node groups, see Defining Nodes and Node Groups. Planning Services for Your ClusterEach node group must be assigned core services that are defined by core services lists. The core service list that you assign to a node group depends on the role of the node group. The following table summarizes the core service lists. Table 4-1 Predefined Core Service Lists When the core services have been defined, optional services can be added. The following table describes the optional service lists.
