AIX - Introduction to Logical Partitioning

AIX - Introduction to Logical Partitioning
1. What is logical partitioning?

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 or LPAR We can install different operating system on each logical partition, and each logical partition runs as an independent logical server with independent operating system and the resources that you have allocated to the logical partition. Processors, memory, and input/output devices are examples of resources that you can assign to logical partitions. Following are the Operating systems which can be installed on each independent Logical partition.

AIX,

i5/OS,

Linux operating systems and Virtual I/O Server.

All the Logical partitions partitioned from a single server share a few system attributes, such as the system serial number, system model, and processor feature code. All other system attributes on each Logical partition can vary from one logical partition to another.
