Using Oracle VM Server for SPARC (logical domains) technology, SuperCluster provides flexible virtualization with both dedicated domains, established during initial install, and dynamically created SR-IOV domains created any time as required. In SuperCluster terminology, the term domain refers to a logical domain. Additionally, there are different types of domains which are described in subsequent sections.
The number of domains supported on each compute server depends on the number of CMIOUs that are in each PDomain:
PDomains with one CMIOU — One domain
PDomains with two CMIOUs — One or two domains
PDomains with three CMIOUs — One to three domains
PDomains with four CMIOUs — One to four domains
For SuperCluster, there are two main types of domains:
