IBM AIX vs. SAP NetWeaver BPM

IBM AIX is well suited for mission-critical applications, especially the ones that need to run on well-performing hardware and need less downtime. It is also perfect for applications that need a lot of CPU, because AIX scales well on the IBM POWER hardware, so adding additional CPU almost always generates higher performance/throughput. IBM AIX runs unmodified from the smallest IBM POWER machine (S1022, with 12 Power10 cores) to the biggest machine (E1080, with 240 Power10 cores). Because IBM POWER systems have very fast CPU’s, you typically need a lower number of CPU’s when compared to alternatives. This may bring a reduction in cost for software licensed per core. Unfortunately, not all software vendors port their software to IBM AIX, so sometimes you may have to run Linux on POWER, or skip the POWER platform altogether. But many vendors happily support AIX and POWER.

It is well suited when we need to integrate business processes with SAP ERP and SAP CRM - the solution can be integrated with business rules/procedures defined in SAP ERP/CRM and NetWeaver can be used to monitor the rules and flag off exceptions. When there are multiple workflows running, it tends to slow down running of these processes. Also, it entirely depends on SAP portal for it to run efficiently.

• Stability. In the 14 years that I have used the product, I cannot think of a single time that we had an OS level failure. It is rock solid. We have had systems that have been booted and run for literally years without interruption.
• Virtualization. We run IBM AIX as LPARS on Power infrastructure. All of our AIX infrastructure is virtualized making it easy to scale as needed.
• Their logical volume manager makes the task of managing storage very simple. It is feature complete and they have mitigated much of the complexity that usually is inherent in LVM implementations.
• I have a love/hate relationship with Smit. It is their administrative interface. It is very powerful and very complete which is why I marked it as a pro. It is also a bit clunky and somewhat arcane in its interface but still usable.

• Virtual paper trail. Iterations of process and current documentation are all stored as "artifacts", leaving a great trail.
• Configuration of users. BPM somewhat magically determines which users will be impacted and automates rules.
• A pro (that is also a con) is the design interface. If you know what you are doing, it is incredibly powerful and malleable.

• 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!

• Live readings would be nice.
• Easier to maneuver
• Work with all systems with the press of one keystroke

As a big fan of SAP in general, the BPM solution fits right in with all the other things SAP does well, and does it with incredible efficiency

AIX is robust, helps the systems administrator, is built to prevent easily made mistakes. If you are used to other variants of Unix (in particularly Linux) there is no steep learning curve to get started with AIX. You need to learn the intricacies of the operating system, but that is true for any new operating system. AIX has built-in tools for almost anything you want and has the AIX Toolbox (on the web) for tools that are not included with AIX by default, but can be installed. Installation of AIX is modular, you can select with components and features you want to have installed. Installation of additional components (and usually also removal of installed components) is easy and straight-forward.

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.

We have our own tech support for systems, I would say they probably could use more training on it, I don't really think it's anything regarding the SAP system, but more the knowledge they have on the system itself. It seems to take longer for them to fix any issues we may come across.

IBM AIX operating system is advanced with most features and also it's more reliable unlike Redhat Linux, Sun solaris, HP-UX and also we will have well support from the vendor if we run into any issues. IBM AIX is more user-friendly when compared to linux and easy to use so i would prefer the customers to have their operating system as IBM AIX for companies who has more customers.

I found the initial setup of NetWeaver is much simpler than other products especially in an SAP environment where we have SAP ERP/HRM/CRM as it can be well integrated with other SAP products. The only drawback is the need/dependency on SAP Portal. It is better suited in an environment where SAP ERP is running.

• 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

Incentivized

• Helped us harness integrated benefit from having SAP ERP/CRM by leveraging NetWeaver to define business processes/rules and monitor exceptions
• Did not have any negative experience except for the fact that at times when multiple rules run, it can be somewhat slow
