The Oracle VM Server for SPARC was formally known as Solaris Logical Domains (LDoms). Oracle VM Server for SPARC is a virtualization technology that lets you create independent virtual machine environments on the same physical system. Oracle VM Server for SPARC provides a virtualized computing environment abstracted from all physical devices, which lets you consolidate and centrally manage your workloads on a system. The logical domains can be specified roles such as a control domain, service domain, I/O domain, and guest domain. Each domain is a full virtual machine where you can start, stop, and reboot the operating systems independently.

Terminology for Oracle VM Server for SPARC

Some of the sample deployment scenarios that are supported by SF Oracle RAC are as follows:

Deployment scenarios Benefits
Oracle RAC database on I/O domains of two hosts
  • The computing resources on the hosts are available to other LDoms.
  • Direct access to storage ensures better database performance.
Oracle RAC database on Guest domains of two hosts
  • The configuration provides a completely virtualized domain.
  • The hardware resources can be effectively utilized with other LDoms.
Oracle RAC database on Guest domains of a single host
  • The reduction in the number of physical servers used makes it a very cost-effective setup.
  • The setup is easy to create and maintain. It is also flexible and portable.
  • Many guest LDoms from multiple systems can be joined together to form a bigger cluster.
  • If the primary domain reboots, only the attached guest LDom is affected. The guest LDom attached to the secondary service domain continues to be available. Please note that shutting down the primary domain halts all domains.
Oracle RAC database on Guest domain and I/O domain of a single host
  • Guest LDoms can be added to the host at any time.
  • The setup offers better disk performance.
  • If the primary domain reboots, only the attached guest LDom is affected. The guest LDom attached to the secondary service domain continues to be available. Please note that shutting down the primary domain halts all domains.
