Hardware support comparison

AIX is built to run on IBM Power Systems, and to fully exploit the new technologies introduced with each generation. Below you’ll find the recommended levels for each version and technology level, but also consider what hardware compatibility mode you’ll be able to run in with each version. You’ll always get the best performance and efficiency on the latest generation’s native mode.

• POWER8 (1) - AIX 5.3 (2, 3), AIX 6.1, AIX 7.1, AIX 7.2
• POWER7 - AIX 6.1, AIX 7.1, AIX 7.2
• POWER6 - AIX 6.1, AIX 7.1
• POWER5 - AIX 6.1, AIX 7.1
• POWER4 - AIX 6.1, AIX 7.1

1. AIX is not supported on POWER8 L or LC models.
2. AIX 5.3 requires full I/O virtualization on POWER8.
3. 7.1 Versioned WPARs are an option to run AIX 5.2 and AIX 5.3 environments on POWER8.

AIX release roadmap

Technology Levels (TLs) are minor releases that allow you to take advantage of new features without major disruption. TLs have a lifecycle of 3 to 4 years, depending on the frequency and maturity of the release. Past the end of the last TL’s lifecycle, IBM offers both Service Extension and sometimes Extended Support options for each AIX Version.

All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only.

AIX Editions

You can purchase AIX either on its own, or bundled with supporting software. Both editions can be ordered with either of the currently offered versions: AIX 7.1 or AIX 7.2.

AIX Standard Edition

(Product ID: 5765-G98)

This is the AIX operating system –it’s the platform you want for your mission critical data. And it fully takes advantage of the IBM Power Systems platform.

• Licenses are priced per core and by processor size, and are available perpetually or on a monthly basis. Perpetual licenses may be purchased with either a one-year or three-year maintenance agreement.

AIX Enterprise Edition V1.2

(Product ID: 5765-CD1 for AIX 7.1, 5765-CD3 for AIX 7.2)

In addition to the AIX Standard Edition operating system, this includes software to help effectively manage, optimize and secure your Power Systems infrastructure.

• IBM Cloud PowerVC Manager V1.3 manages private cloud deployments

• IBM PowerSC V1.1 ensures security profile compliance

• IBM Tivoli Monitoring V6.3 monitors the health, availability, and performance

• IBM BigFix Lifecycle V9.2 provides centralized patch management

• The AIX 7.1 Enterprise Edition product also includes AIX Dynamic System Optimizer, in AIX 7.2 this is included in the Standard Edition.

• Licenses are priced per core and by processor size. May be purchased with either a one-year or three-year maintenance agreement.


Running AIX Version 5.X applications

Migrate to AIX V7 and POWER8

Be assured of your software compatibility with the binary compatibility guarantee.

POWER8 support for AIX 5.3

Run these workloads natively on POWER8 for a limited time.

Run AIX 5.X applications under AIX V7 with versioned workload partitions

Minimize the effort to consolidate older AIX workloads on the latest generation of Power Systems servers. Now you can more efficiently manage the lifecycle of your legacy AIX environments.
