Managed systems
A managed system is a single physical server plus the resources that are connected to the physical server. The physical server and the connected resources are managed by the physical server as a single unit. Connected resources can include expansion units, towers, and drawers, and storage area network (SAN) resources that are assigned to the server.
You can install a single operating system on a managed system and use the managed system as a single server. Alternately, you can use a partitioning tool, such as the Hardware Management Console (HMC) or the Integrated Virtualization Manager to create multiple logical partitions on the managed system. The partitioning tool manages the logical partitions on the managed system.
