CPU Caps

This system resources enhancement is new in the Developer 9/07 release.

CPU caps provide absolute fine-grained limits on the amount of CPU resources that can be consumed by a project or a zone. CPU caps are provided as a zonecfg resource, and as project and zone-wide resource controls.

• The zonecfg capped-cpu resource provides an absolute limit on the amount of CPU that can be consumed by a project or a zone.

• The following resource controls are available:

  zone.cpu-cap

  Absolute limit on the amount of CPU resources that can be consumed by a non-global zone.

  project.cpu-cap

  Absolute limit on the amount of CPU resources that can be consumed by a project.
