Designing Disaster Tolerant High Availability Clusters
HP ServiceControl
HP ServiceControl is a system management environment including high capacity HP
HyperPlex clusters. It provides a consolidated point for managing your workload,
applications, and resources on your system from a single management station. High
availability products, such as Serviceguard and HA Monitors, reside physically on the
HyperPlex cluster nodes.
HP ServiceControl organizes nodes into HyperPlex clusters. Within these clusters,
Serviceguard minimizes and eliminates application downtime by
• Protecting mission-critical applications from a variety of hardware and software
failures by monitoring the health of each node.
• Balancing the workload on a system by responding quickly to changes and
workload demands.
