No limits are placed on how much disk space can be consumed by a zone. The global zone administrator is responsible for space restriction. Even a small uniprocessor system can support a number of zones running simultaneously. The characteristics of the packages installed in the global zone affect the space requirements of the non-global zones that are created. The number of packages and space requirements are factors.
For complete planning requirements and recommendations, see Chapter 18, Planning and Configuring Non-Global Zones (Tasks), in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.
