The Global Zone and Its Projects

The global zone is the only zone that is not bound to only one resource pool. It can get CPU resources from any pool. Projects in the global zone can obtain CPU resources from every resource pool on the host because a hidden global zone is present in every resource pool on the host.

For example, the resource pool, Pool_default, has 4 CPUs and has zone_1 and zone_2 deployed on it. The Pool_default has 10 CPU shares. Zone_1 has 5 CPU shares, zone_2 has 4 CPU shares and the global zone has 1 CPU share.

Another resource pool, Pool_1, has 2 CPUs and has 10 CPU shares. Pool_1 has only one zone, zone_3 deployed. Zone_3 has 9 CPU shares. The global zone has 1 CPU share.

The projects in the global zone get their CPU resource from the 1 CPU share of the pool that they are deployed on.

In Solaris Container Manager, projects in the global zone must be deployed to pool_default.
