AS400

https://brmlab.cz/project/as400_midrange

The IBM System i, then known as the AS/400, was the continuation of the System/38 database machine architecture (announced by IBM in October 1978 and delivered in August 1979). The AS/400 removed capability-based addressing.The AS/400 added source compatibility with the System/36 combining the two primary computers manufactured by the IBM Rochester plant. The System/36 was IBM's most successful mini-computer but the architecture had reached its limit. The first AS/400 systems (known by the development code names Silverlake and Olympic) were delivered in 1988 under the tag line “Best of Both Worlds” and the product line has been refreshed continually since then. The AS/400 - formally renamed the “IBM iSeries,” but still commonly known as AS/400 - is a midrange server designed for small businesses and departments in large enterprises and now redesigned so that it will work well in distributed networks with Web applications. The AS/400 uses the PowerPC microprocessor with its reduced instruction set computer technology. Its operating system is called the OS/400. With multi-terabytes of disk storage and a Java virtual memory closely tied into the operating system, IBM hopes to make the AS/400 a kind of versatile all-purpose server that can replace PC servers and Web servers in the world's businesses, competing with both Wintel and UNIX servers, while giving its present enormous customer base an immediate leap into the Internet.

MAINFRAME

The mainframe owes much of its popularity and longevity to its inherent reliability and stability, a result of careful and steady technological advances that have been made since the introduction of the System/360™ in 1964. No other computer architecture can claim as much continuous, evolutionary improvement, while maintaining compatibility with previous releases. Because of these design strengths, the mainframe is often used by IT organizations to host the most important, mission-critical applications. These applications typically include customer order processing, financial transactions, production and inventory control, payroll, as well as many other types of work.
