Executive Summary

Different business needs require different environments. Environments vary widely in their tolerance for unplanned downtime, their hardware configuration, specialized software, and system and data management. These factors require careful consideration when configuring a high-availability environment. Thorough testing in a production or near-production environment should be done to make sure that the configured cluster meets the requirements. Testing and fine-tuning can help optimize failover time and increase application availability to end users. This paper explains the HP Serviceguard failover process and discusses how one can optimize cluster failover time.
