System WPARs
System WPARs are autonomous virtual system environments with their own private file systems, users and groups, login, network space and administrative domain.
Most traditional system services are virtualized at the WPAR level, and they can be independently used and managed within each WPAR. While the system WPAR environment is largely partitioned and isolated, read-only file systems might be shared between WPARs to facilitate the sharing of application data and text. Versioned WPARs can only be non-shared system WPARs.
