Why Is AS400 Still So Popular?

Although the AS/400 was technically renamed as the IBM iSeries, the moniker AS/400 is still widely used. It’s a mid-range system that was originally meant for smaller companies and divisions within larger corporations but has now been modified to perform well in multiple systems with Web apps. The PowerPC chip, with its restricted authorization procedure computer technology, is used in the AS/400. The OS/400 is the name of its operating system.

Between multi-terabyte disc storage as well as a Java memory allocation tightly integrated into the os, IBM appears to be making the AS400 managed services an adaptable all-purpose platform that can supplant PC hosts and Data centers in the worlds largest enterprises, contending with Wintel and UNIX servers while providing an instant leap onto the Net to its current vast client base.

Basic use of AS/400

The AS/400 design is frequently seen in ERP or other quest operations, especially in sectors that demand accuracy and consistency, such as manufacture. SAP users like IBM Power Systems, as well as competitor database systems.

With the development of the AS/400 cloud, the IBM model is becoming a more common cloud-based solution. IBM collaborates closely with distribution channels to deliver AS/400 services for a variety of applications. At this moment, AS400 managed services can host anything, but various use instances may necessitate quite different setups.

Reason for AS/400 to be still in use

As far back as the 1980s, IBM Power Generation pcs have been a staple enterprise IT department. From the original AS/400 to the contemporary IBM iSeries, they have been prized for their speed, reliability, and durability.

The famed AS/400 performance and dependability are preserved by BM Power Systems. The IBM AS/400 server was designed to be bullet-proof, with substantial hardware redundancy, especially at the top of the line. It’s also tremendously fast, with CPUs that are 3-5 times faster than the competition. These features are perfect for applications like SAP hosting, which demand extremely high performance and little downtime.

  • There are several AS/400 choices to choose from

From entry-level systems to high-power, massively redundant servers for bigger enterprise customers to scalable models for ever-expanding data centers, there’s something for everyone. AIX, IBM I SUSE, and RedHat Enterprise Linux are among the operating systems supported by the IBM iSeries.

  • It is not cost-effective to switch away from IBM Power Systems.

Although IBM Power Systems are expensive per unit than rivals, their processors are far more efficient. In a keynote speech, IBM demonstrated that Power Systems LC workstations outperform Intel Proliant in cost and performance in both solo and dual computers. Keep in mind that this is an IBM test, and there are no high assurance numbers because performance varies depending on design and application. So at the least, this demonstrates that the IBM AS/400 is competitively priced.


To conclude, the use of AS/400 is still active amongst the comp[anies due to the reasons mentioned above. Hopefully, by now, the use of AS/400 and the reason behind it must be clear to you.
