Organizations that run SAP on IBM iSeries (AS/400) have long benefited from the platform’s stability and performance. Yet, your ERP requirements continue to evolve as the iSeries ages and becomes costlier to maintain on-premises. New IBM private cloud options have emerged to address this challenge. With a Managed Service Provider (MSP), you can preserve the continuity of iSeries for SAP, but with a third party doing the heavy lifting of running iSeries in a private cloud environment.
SAP on iSeries: A Long, Auspicious Relationship
The IBM iSeries, previously known as the AS/400, quickly became one of the world’s most popular business computing platforms when it debuted in 1988. Its install based exceeded 100,000. Belonging to the “midrange” or minicomputer class, the iSeries offered businesses an affordable alternative to the dominant mainframes of the era. It runs AIX, a proprietary variant of the Unix operating systems.
SAP has enjoyed a long, auspicious relationship with iSeries. Many of SAP’s small-to-midsized business (SMB) customers run SAP on iSeries. Large enterprises rely on it for their SAP landscapes as well. They have good reasons. iSeries is famous for its stability, reliability and high performance. It also features backward compatibility that favors the kind of long-term investments in ERP that SAP customers prefer. Indeed, SAP was founded by former IBM’ers in 1972. The SAP-iSeries connection is a natural fit.
The Migration Decision
What you should do with your SAP on iSeries? One very appealing answer is “nothing.” The landscape is very much alive and supported worldwide. If you run SAP on iSeries on-premises, you can continue to do so for the foreseeable future.
At the same time, a lot of organizations are starting to take a look at their options for what comes after iSeries on-premises. There are two basic problems that affect the long-term viability of iSeries on-premises:
- A looming skills shortage—iSeries staff are starting to retire. Few in the up-and-coming generation of IT professionals are making the investment in learning AIX and SAP on iSeries. It’s probable that staffing to support an SAP landscape on iSeries will grow more challenging and costly in coming years.
- New, cloud-centric requirements—Enterprise architecture increasingly calls for SAP landscapes to integrate across multiple clouds as well as with other applications. This is of course possible for iSeries on-premises, but it may require the costs of adding middleware that then needs maintenance, patching and so forth.
Migrating off of iSeries completely is an option, but one that some SAP administrators are justifiably circumspect about. For one thing, it can take a lot of standard hardware (e.g. Dell or HPE rack servers) to replace a single iSeries machine. This creates CapEx and increased OpEx for data center space. Then, there’s the software itself. If you’ve been running SAP on iSeries for a decade or more, you’re going to find more than a few little “gotchas” when migrating to a X86 platform. You can overcome these challenges, but there will be costs and delays.
