The Workload Manager—a feature included in the base AIX operating system (OS) since AIX Version 4.3.3—helps you manage workloads and resources by allowing you to control the amount of resources such as processor capacity or memory that an application can use. Workload Manager enables you to run multiple applications on a single server by allowing you to control the amount of resources each application can consume.
Workload Manager also allows you to enforce business priorities on your workloads to help ensure that critical customer applications are not impacted by the resource requirements of less critical jobs in the system. Organizations can take advantage of server consolidation and reap the cost and management benefits associated with centralized systems administration. You can easily apply individually tailored resource-allocation profiles, which allows you to spend less time on routing workload tasks.
In AIX V6.1, Workload Manager is the primary infrastructure used to regulate the resource usage for Workload Partitions. Workload Partitions, used in conjunction with the Workload Manager, enables you to easily consolidate multiple workloads in a single AIX OS instance.
