Dedicated Domains
The following SuperCluster-specific domain types have always been available:
Application Domain running Oracle Solaris 10
Application Domain running Oracle Solaris 11
Database Domain
These SuperCluster-specific domain types have been available in software version 1.x and are now known as dedicated domains.
Note - The Database Domains can also be in two states: with zones or without zones.
When a SuperCluster is set up as part of the initial installation, each domain is assigned one of these three SuperCluster-specific dedicated domain types. With these dedicated domains, every domain in a SuperCluster has direct access to the 10GbE NICs and IB HCAs (and Fibre Channel cards, if those are installed in the card slots). The following graphic shows this concept on a SuperCluster with four domains.
With dedicated domains, connections to the 10GbE client access network go through the physical ports on each 10GbE NIC, and connections to the IB network go through the physical ports on each IB HCA, as shown in the following graphic.
With dedicated domains, the domain configuration for a SuperCluster (the number of domains and the SuperCluster-specific types assigned to each) are set at the time of the initial installation, and can only be changed by an Oracle representative.
