IBM PowerHA technology provides high availability, business continuity and disaster recovery. It enables you to deploy an HA solution that addresses both storage and high availability requirements with one integrated configuration, which offers robust performance along with a simplified user interface. Power Systems is committed to investing in - and bringing to market - solutions designed to keep your IT environments resilient.

If a cluster node or service fails, the services that were hosted on that node can be automatically or manually transferred to another available node in a process known as failover.
