HP Serviceguard Toolkit for Integrity Virtual Servers manual Supported configuration

2 Supported configuration

This section explains the supported configuration for VM or vPar-as-Serviceguard-packages. Figure 1 (page 7) represents a basic VM or vPar-as-a-Serviceguard-package (or, VM or vPar guest as packages) model configuration as supported with the SG IVS toolkit.

Figure 1 VM/vPar as Serviceguard packages

In this configuration, a Serviceguard cluster is formed by using VM or vPar Host systems as nodes in the cluster. The VM or vPar guests are then encapsulated within Serviceguard packages to provide high availability for the VM or vPar guests that are used to run the applications.

The VM or vPar guest in the Serviceguard package is protected against VM or vPar Host system hardware or software failures, in addition to VM or vPar failures. If a VM or vPar fails, the Serviceguard package containing the VM or vPar guest can fail over to another VM or vPar Host within the Serviceguard cluster.

For more information on configuring shared storage for HP Serviceguard clusters, see the latest Managing Serviceguard manual available at http://www.hp.com/go/hpux-serviceguard-docs → HP Serviceguard.
