description IBM AIX Overview

IBM AIX is a proprietary Unix operating system developed by IBM for enterprise computing. It has been used primarily on IBM POWER and earlier RS/6000 systems, where it supports administrative tools, filesystems, workload management, and virtualization through technologies such as logical partitions. AIX is designed for organizations operating long-lived business applications that require a Unix environment on IBM hardware.

help IBM AIX FAQ

What hardware does IBM AIX run on today?

Modern AIX is designed for IBM Power Systems rather than ordinary x86 PCs. Its history includes the RS/6000 line, and IBM documents current AIX releases such as AIX 7.3 for Power environments.

What is an LPAR in IBM AIX?

An LPAR is a logical partition that divides an IBM Power server into separate virtual machines with allocated processor, memory, and I/O resources. Multiple AIX instances can therefore share one physical Power server under IBM PowerVM.

Which AIX versions are still relevant for enterprise systems?

IBM lists AIX 7.2 and AIX 7.3 as supported release lines in its lifecycle material. AIX 7.3 was released in December 2021, although exact support depends on the technology level and hardware.

Can AIX update an active workload without a traditional reboot?

AIX includes Live Update capabilities for supported configurations, including documented support for operations on an LPAR managed by PowerVC. The exact procedure depends on the AIX level, PowerVM environment, and workload.
