Partitioning concepts

Before you can start installing BOS on partitions you need to learn about general ideas and terminology.

Logical partitions
A logical partition (LPAR) is the division of a computer's processors, memory, and hardware resources into multiple environments so that each environment can be operated independently with its own operating system and applications.
Managed system
A managed system is a system that is physically attached to and managed by the Hardware Management Console (HMC).
Dynamic logical partitioning
Dynamic logical partitioning provides the ability to logically attach and detach a managed system's resources to and from a logical partition's operating system without rebooting.
Affinity logical partitions
An affinity logical partition is a special type of logical partition that uses system resources that are in close physical proximity to each other.
Full system partition
A special partition called the Full System Partition assigns all of your managed system's resources to one large partition.
Running AIX on a logical partition
There are several differences between how AIX runs on a logical partition and how it runs on a standalone server.
Remote management
You can connect your browser to the Hardware Management Console (HMC) to manage your partitions remotely or use the command line.
Partition security
System administrators can install a server with the Evaluation Assurance Level 4+ (EAL4+) option during a base operating system (BOS) installation. If you select this option, there are restrictions on the software that is installed during BOS installation and network access restrictions.
