Thats correct

HP Serviceguard is specialized software for protecting mission-critical applications from a wide variety of hardware and software failures. With Serviceguard, multiple servers (nodes) and/or server partitions are organized into an enterprise cluster that delivers highly available application services to LAN-attached clients. HP Serviceguard monitors the health of each node and rapidly responds to failures in a way that minimizes or eliminates application downtime.

Regards!
