Logical partitioning

You can set up, manage, and troubleshoot AIX®, IBM® i, Linux, and Virtual I/O Server logical partitions using the Hardware Management Console (HMC), Integrated Virtualization Manager, or Virtual Partition Manager. By creating logical partitions, you can reduce the footprint of your datacenter by consolidating servers, and maximize the use of system resources by sharing resources across logical partitions.

Logical partition overview
Logical partitioning is the ability to make a server run as if it were two or more independent servers. When you logically partition a server, you divide the resources on the server into subsets called logical partitions. You can install software on a logical partition, and the logical partition runs as an independent logical server with the resources that you have allocated to the logical partition.
Scenarios: Logical partitions
One of the best ways to learn about logical partitions is to see examples illustrating how many of the applications and functions can be used in a sample business environment. Use these scenarios to learn how you can use logical partitions in your business.
Planning for logical partitions
You can create logical partitions to distribute resources within a single server and make it function as if it were two or more independent servers. Before creating logical partitions, you must assess your current and future needs. You can then use this information to determine the hardware configuration that will meet your current needs and serve as a base for meeting your future needs.
Partitioning with the HMC
The Hardware Management Console (HMC) is a system that controls managed systems, including the management of logical partitions and use of Capacity Upgrade on Demand. Using service applications, the HMC communicates with managed systems to detect, consolidate, and forward information to IBM for analysis.
Integrated Virtualization Manager
You can use the Integrated Virtualization Manager (IVM), a component of the PowerVM® Editions hardware feature, to manage your Virtual I/O Server and client logical partitions.
