Solaris provides a means of virtualizing operating system services, allowing one or more processes to run in isolation from other activity on the system. Such a "sandbox" is called a "non-global zone." Each zone can provide a rich and customized set of services. The processes that run in a "global zone" have the same set of privileges that are available on a Solaris system today.

VCS provides high availability to applications running in non-global zones by extending the failover capability to zones. VCS is installed in a global zone, and all the agents and the engine components run in the global zone. For applications running within non-global zones, agents run script entry points inside the zones. If a zone configured under VCS control faults, VCS fails over the entire service group containing the zone.

The Veritas agent for SAP WebAS is zone-aware and can monitor SAP instances running in non-global zones.
