A logical domain is a discrete logical grouping of operating systems, resources, and identities within a single computer system. Application software can run in logical domains. Each logical domain can be created, destroyed, reconfigured, and rebooted independently.
Oracle VM Server for SPARC software enables you to create and manage logical domains. The number of logical domains you can create depends on the hardware configuration of the server on which Oracle VM Server for SPARC Manager is installed. A PDomain with a single DCU can have as many as 128 logical domains, but to follow the best practice of aligning logical domains on core boundaries, you should configure no more than 48 logical domains per PDomain.
You can virtualize resources and define network, storage, and other I/O devices as services that can be shared between domains.
The Oracle VM Server for SPARC configurations are stored on the SP. Using Oracle VM Server for SPARC CLI commands, you can add a configuration, specify a configuration to be used, and list the configurations on the SP. You can also use the Oracle ILOM set /Servers/PDomains/PDomain_x/HOST/bootmode config=configfile command to specify an Oracle VM Server boot configuration.
