13.5. Additional Information

Heartbeat 2 is now part of SUSE® Linux Enterprise 10. A Heartbeat 2 cluster can be installed and configured using the YaST setup tool. During the Heartbeat 2 installation, you are prompted for information that is necessary for Heartbeat 2 to function properly. This section contains information to help you install and configure a Heartbeat 2 cluster.

This cluster installation program does not copy the Heartbeat software package to cluster nodes. Prior to running this installation program, the Heartbeat software package must be installed on all nodes that will be part of your cluster. This can be done during the SUSE Linux Enterprise 10 installation, or after.

This installation program lets you create a new cluster or add nodes to an existing cluster. To add new nodes to an existing cluster, you must run this installation program from a node that is already in the cluster, not on a node that you want to add to the cluster.

13.1. Hardware Requirements

The following list specifies hardware requirements for a Heartbeat 2 cluster. These requirements represent the minimum hardware configuration. Additional hardware might be necessary depending on how you intend to use your Heartbeat 2 cluster.

  • A minimum of two Linux servers

    The servers do not require identical hardware (memory, disk space, etc.)

  • At least one communications medium (Ethernet, etc.) that allows cluster nodes to communicate with each other
