IBM i Architecture

Dr. Wolfgang Rother

Abstract

The basic architecture of IBM i was inspired by the design of the IBM S/38 and S/36 and was first implemented in the OS/400 operating system of the Application Systems 400 (short AS/400) in 1988. Although many innovations have been introduced during the more than 30 years of its use and new ones are added every year, the basic architecture remained unchangedh. Concepts such as the technology independent machine interface, single level store, object-based design, it's work management and the integration of a relational database into the operating system are so different from the architecture of Windows and Linux that it is worth taking a closer look. Therefore the IBM i architecture can be used as an alternative example in lectures on operating systems.

Two videos were integrated into the openHPI course "Future of Computing - IBM POWER9 and beyond" available at https://open.hpi.de/courses/ibmpower2019.

After working several years as an assistant lecturer for probability theory, I joined IBM in 1997 as a lecturer teaching courses on AS/400 and Novell integration. I added more and more topics and also more business responsibilities for iSeries training offerings inside Germany and DACH. I worked as curriculum manager, team leader and Regional Offerings Deployment Manager for iSeries Offerings in Central Region.
In 2005 I was promoted to Business Development and Skills Manager inside Germany's IBM Power Platform Team and got more responsibilities for IBM's Power Systems business and channel enablement. After some years working for the IBM STG Client Technical Sales Team for IBM Power Systems I'm again a member of the IBM Power Platform Team. Beside of hardware and IBM i skill my expert topics today are also cloud offerings and business analytics solutions based on Power Systems.
Since 2005 I have been a guest lecturer at several universities on topics such as operating systems and computer architecture.
