IBM AIX vs. SUSE Linux Enterprise Server

IBM AIX is a very powerful and extremely stable operating environment. It is well suited for applications that are business critical and cannot tolerate outages. It is best used to address large enterprise level application needs where stability and scalability are of paramount importance. IBM AIX is less useful for small enterprises.

SLES has been the only OS for our large SAP landscape in North America and has been adopted by the rest of our global divisions because of our performance. We have not encountered any scenarios where SLES is not a good choice. We only use other OS when the vendor will not support SLES.

• The newer version of IBM AIX allows to apply new patches without system restart
• IBM AIX was the first operating system to have a journaling file system and have enhanced software features.
• IBM AIX will have good vendor support 24/7 and will ensure reliability to the customers and more performance when compared to it peers.

• Consistently performs well across various CPU architectures.
• It's very well supported both by the parent company, as well as SAP and other third-party companies.
• It is upgradeable across versions. We've performed upgrades from version 10 to 11 and from 11 to 12 without any major issues.

• A lot of the built-in commands have not been updated in years. If you're used to some fancy CLI options in Linux, you may be out of luck with AIX.
• Out of the box, you cannot run open-source Linux utilities on AIX. There is a toolbox you can install, however, it's not the same versions as you would get in different Linux flavors.
• Tab completion for files and Up arrow to re-run previous commands don't work out of the box without running a Korn shell. A small annoyance, but one that catches me every time!

• The support window for service packs after a new SP is released is too short.
• Community engagement is low.
• There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.

For the breadth of services, features and overall performance, I believe Suse Linux is a great choice for any enterprise. It still has to grow a bit in areas like online help forums and documents, but we are pretty much satisfied with our choice.

There is lots of documentation out there for AIX. On the times I've had to address a hardware issue, IBM's support has been great.

Support personnel are helpful and fairly fast to bring resolution to non-emergency issues. Patches are created and posted in a timely fashion. We so far have not had any major problems that needed support

Third party training was fast but mostly unnecessary as we were already Unix trained and Linux familiar

Standard Linux distributions which are used more as commodity servers do not offer the ease of scale and growth that we see with our Aix implementations. IBM owning the HW and SW portions of the stack allows for tighter integrations and better performance windows.

We went straight to SLES when we initially started migrating oracle to hana since at that time, HANA came on a pre-installed server that had to be purchased from an official vendor, and SLES was the only allowed OS. We stuck with SLES after we became certified to do our own installations because so far, SLES was a good fit for us.

We have successfully deployed on physical servers, VMs and in cloud all over the globe from templates of our own design

• IBM AIX on Power hardware has been the backbone of our most critical applications.
• The versatility of IBM AIX virtualization has been extremely useful, scalable, and provided configuration with redundant dual VIO servers.
• IBM AIX is not Linux so special skill sets are needed to actually manage the systems. Finding qualified engineers can often be a challenge

• Compared to others, use is more stable and scalable; easy to manage.
• The administration tools are very useful in helping the staff performance.
• SLES proved to be a very extendable product, supporting all of our infrastructure.
• The major reason I chose to use the product was the extensive enterprise peripheral support.
