Oracle I/O Domain Administration Guide

SuperCluster Domain Overview

Oracle personnel customize each SuperCluster with domain (LDom) configurations according to site requirements. Each domain operates on its own set of compute resources, including CPU, memory, and I/O devices. As of SuperCluster version 3.0, you can view the domain configurations in the SuperCluster Virtual Assistant Dedicated Domains page (see View System Resources)

This table lists SuperCluster-specific domain types and describes how CPU, memory, and networking resources are managed.

I/O Domain Domain Type Description Application Domains and Database Domains Dedicated Provide these services: Application Domain – Boots and runs on Oracle Solaris 11, and hosts application services. Database Domain – Domains where you install and run the Oracle Database software. An Oracle Database software installation benefits from the performance of Exadata technology. These domains can not run any OS release prior to Oracle Solaris 11. Database Zone Domain – Domains where you can install multiple Database Zones. These domains can not run any OS release prior to Oracle Solaris 11. You can use these domains as-is, or use the osc-setcoremem utility to set aside a certain amount of their CPU and memory resources. The resources that are set aside are parked, and available for use in I/O Domains. For more information on the osc-setcoremem utility, refer to the Oracle SuperCluster T5-8 Owner’s Guide or the Oracle SuperCluster Administration Guide for your model (for example, Oracle SuperCluster M8 and SuperCluster M7 Administration Guide). As of SuperCluster version 3.0 (and later), you can view the dedicated domains in the SuperCluster Virtual Assistant's Dedicated Domains tab. See View System Resources. Root Domain Dedicated Supports SR-IOV functionality by hosting I/O devices. Root domains reserve a small set of resources for I/O hosting functionality. The remaining resources are parked, creating a pool of resources that you can further dynamically virtualize into I/O Domains. As of SuperCluster version 3.0 (and later), you can view the root domains in the SuperCluster Virtual Assistant's Dedicated Domains tab. See View System Resources. I/O Domain SR-IOV You create, delete, and deploy I/O Domains using the SuperCluster Virtual Assistant. The assistant enables you to assign resources from the CPU and memory repositories, and from virtual functions hosted by Root Domains. When you configure an I/O Domain, you assign it as an Application Domain, a Database Domain, or a Database Zone Domain. These I/O Domains provide the same functionality as dedicated Application and Database domains, with the added flexibility of being able to delete and add domains as needed (limited by available resources). I/O Domains cannot run any OS releases prior to Oracle Solaris 11. A Database Zone Domain supports multiple Database Zones. You can view the I/O domains in the SuperCluster Virtual Assistant's I/O Domain tab. See View I/O Domains.
