- Workload Partitions
Workload partitions (WPARs) are a software implementation of
operating system-level virtualization technology introduced in the IBM's 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
system p hardware that supports AIX 6.1. There are two kinds of WPARs, System WPARs and Application WPARs.ystem WPAR
System WPARS are virtual system environments that closely resembles a
LPAR or a complete separate system. WPARs have their own private file systems, users and groups, login, network space, and administrative domain. All WPARs share the same global AIX kernel.Application WPAR
Application WPARs are light weight environments used for isolating and executing one or many application processes.
Mobility
WPAR mobility is an extension to WPARs that provides the functionality to move an actual running workload from one physical machine to another. The feature can be extremely helpful during hardware upgrades.
