HP Serviceguard for Linux is an HA and DR software solution. It packages a critical service – such as an application – together with its associated resources, and monitors the entire package for any faults related to hardware, software, OS, virtualization layer, virtual machine guests, network, or storage. When a failure is detected, HP Serviceguard for Linux gracefully shuts down the application, restarts it on an available server in the cluster, connects it to the appropriate storage device, and resumes normal operations – all in mere seconds, and with minimal impact on production environments (whether physical or virtual).

HP Serviceguard for Linux also includes enhanced package dependencies, which help you craft and control the dependencies between applications in a standardized way. This reduces complexity and provides a more realistic model of the environment, allowing you to manage multiple tiers of applications together in a controlled and well-defined way.

An HP Serviceguard for Linux cluster solution delivers HA using redundant hardware to remove single points of failure to survive multiple node failures.
