IBM AIX Workload Partitions (WPARs) are a software implementation of operating system-level virtualization introduced in the IBM AIX 6.1 operating system that provides application environment isolation and resource control.
WPARs are software partitions that are created from, and share the resources of, a single instance of the AIX OS.
WPARs can be created on any IBM Power Systems or IBM System p hardware that supports AIX version 6.1 and higher .
A system WPAR behaves as a complete installation of AIX.
To continue having access to the same files before/after mobility; the filesystems of a mobile WPAR must either be stored in a disk or NFS mounted (both of which should be shared and accessible from all the machines where WPAR is being moved to).
