Support for Oracle virtual environments

TrueSight Capacity Optimization supports the following types of Oracle Solaris virtual environments: 

Support for Solaris Containers

Oracle Solaris provides a way of virtualization by creating containers, or zones, inside the operating system image. The operating system image that contains the zones is called the global zone. 

A global zone can contain many zones referred to as non-global zones. Each non-global zone appears as an independent node within the network and it maps application resources to platform resources. Applications running within discreet non-global zones are isolated from each other. Global and non-global zones share one copy of the Solaris running in the global zone.

What is supported for this platform:

  • Additional metric data and treatment of non-global zone as a node, with constraints
  • CPU, Paging IO and Total IO metrics at the non-global Zone level

What is not supported:

  • Specific zone reports in BMC Performance Analyzer for Servers or BMC Performance Predictor for Servers
  • Global zone environment information for Containers if you are running Solaris Containers in a DSD environment

Support for Solaris Dynamic System Domains (DSDs)

Due to the limitation of hardware access, only partitions running on SunFire architecture (SunFire 12K, 15K, 20K, and 25K) are supported. Oracle refers to hardware partitions as Dynamic System Domains (DSDs). Each physical SunFire or SPARC system can support multiple partitions, or DSDs.

Support for Solaris Logical Domains (LDOMs)

Oracle refers to logical hardware partitions as Logical Domains (LDOMs). Each physical SunFire and SPARC system can support multiple logical domains. 

LDOMs are virtual environments within the Solaris operating system. Several LDOMs share a physical processor, but each operates like an independent processor. The collector for Solaris identifies each LDOM as if it is an independent processor, as well as sharing processing resources of a physical processor. It returns utilization information and metrics for the physical processor, each LDOM within the processor, and each LDOM's share in the physical processor's total capacity.

What is supported for this platform:

  • Identifying a system as a LDOM or a control LDOM
  • Collecting the Physical Partition Configuration metric group that describes the configuration of the LDOMs running on the server if the collector is running on the control LDOM. The collector also collects existing Solaris core level statistics and other performance and configuration data from each LDOM.
  • Investigate for the LDOM metric groups.
  • Data Analysis that reads and processes the key metrics, identifies and provides the relationships between objects to the database and the model. Support workload characterization of data collected within each LDOM.
  • Presenting key metrics in Datacenter Overview charts and detailed metrics in Solaris LDOM specific charts.
  • Modeling of LDOM systems based on threads instead of cores
  • Collecting, analyzing, modeling and presenting information about zones running within LDOMs.

On x86-based systems, Oracle virtualization technology uses the Xen hypervisor to securely manage and run multiple virtual machines on a host computer. These virtual machines are imported into TrueSight Capacity Optimization as Xen hosts and Xen virtual machines.
