HA for Logical Domains Overview

Oracle VM Server for SPARC (Logical Domains) provides the ability to split a single physical system into multiple, independent virtual systems. This is archived by an additional software application in the firmware layer, interposed between the operating system and the hardware platform called the hypervisor. It abstracts the hardware and can expose or hide various resources, allowing for the creation of resource partitions that can operate as discrete systems, complete with virtual CPU, memory, and I/O devices.

The HA for Logical Domains data service provides a mechanism for orderly startup and shutdown, fault monitoring, and automatic failover of the Logical Domains guest domain service. The Logical Domains component is protected by the HA for Logical Domains data service.
