Creating and Using Oracle® Solaris Zones

Disk Space Requirements

There are no limits on how much disk space can be consumed by a zone. The global administrator or a user with appropriate authorizations is responsible for space restriction. The global administrator must ensure that local or shared storage is sufficient to hold a non-global zone's root file system. Even a small uniprocessor system can support a number of zones running simultaneously.

The nature of the packages installed in the non-global zone affects the space requirements of the zone. The number of packages is also a factor.

The disk requirements are determined by the disk space used by the packages currently installed in the global zone and the installed software.

A zone requires a minimum of 150 megabytes of free disk space per zone. However, the free disk space needed is generally from 500 megabytes to 1 gigabyte when the global zone has been installed with all of the standard Oracle Solaris packages. That figure can increase if more software is added.

An additional 40 megabytes of RAM for each zone are suggested, but not required on a machine with sufficient swap space.
