Chapter 1 # Planning to Install the Hardware Before you install any hardware for your cluster, you must make a few decisions. Decide on the purpose and the hardware configuration of the cluster, and choose the installation method. Include nodes in your cluster plan that you might want to add to the cluster in the future. These decisions can save you time when you begin installing the hardware and software for the cluster. To plan the process of installing the hardware for your cluster, see these sections: Planning the Installation Installing the Hardware (Task Map) ## Planning the Installation The Foundation Services product provides two ways of installing software on the cluster: Installation using the `nhinstall` tool. The `nhinstall` tool enables you to install the Foundation Services on a cluster. This tool is flexible and provides various configuration options that you can adapt to your requirements. However, the `nhinstall` tool only supports the installation of master-eligible nodes and diskless nodes. You can only install dataless nodes manually. Manual installation. You can manually install software on a cluster containing master-eligible nodes, diskless nodes, and dataless nodes. Manual installation provides more flexibility when installing components of the Foundation Services. However, a manual installation can result in a cluster configuration that is not easily reproducible on other clusters. ## Installing the Hardware (Task Map) The following table outlines the tasks for choosing and installing the cluster hardware and the installation hardware:
Task | Description | For Instructions
--- | --- | ---
Choose the installation method. | Choose the method for installing the Foundation Services on the cluster. | Netra High Availability Suite Foundation Services 2.1 6/03 Overview
Choose the hardware configuration of your cluster. | Choose the number and type of nodes of the cluster. Try to include nodes that you might want to add to the cluster in the future. | Chapter 2, Choosing the Cluster Hardware
Install the cluster hardware. | Install the cluster nodes, the Ethernet switches, and the terminal server. | Chapter 3, Installing and Configuring the Cluster Hardware
Install the installation server. | The installation server is required for any installation method you choose. | Installation Server
Install the development host. | If you are planning to develop applications using the Foundation Services API, install a development host. | Development Host
Connect the cluster. | Connect the cluster nodes to the Ethernet switches and the terminal server. Connect the installation server and, if necessary, the development host, to the cluster. | Connecting the Hardware for Installation
