About Resources in Zones
A zone that includes resource management features is called a container. Resources that
can be controlled in a container include the following:
Resource pools or assigned CPUs, which are used for partitioning machine resources.
Resource controls, which provide a mechanism for the constraint of system resources.
Scheduling class, which enables you to control the allocation of available CPU resources among zones, based on their importance. This importance is expressed by the number of shares of CPU resources that you assign to each zone.
