why is as/400 still usedIBM Power Systems computers have been a mainstay of enterprise IT since the 1980s. From the original AS/400 through the current IBM iSeries, they’ve been prized for performance, stability and dependability. However, as enterprise cloud services have continued to replace onsite ERP, some people have written the AS/400 off.


With the ever decreasing cost of cloud hosting, the IBM AS/400 is portrayed by its detractors as an outdated, pricey relic from a bygone age. Additionally, there is a perceived lack of IT support — particularly for companies moving to the cloud — that has led some companies to reconsider their IBM Power Systems infrastructure. However, the criticisms are overstated, and there are good reasons why so many companies still use the IBM AS/400.


Why is AS/400 still used?


  1. IBM Power Systems preserve the legendary AS/400 performance and reliability. 

    The IBM AS/400 was built to be bullet-proof, with massive hardware redundancy — particularly at the upper end of the server line. It’s also extremely high-performing, with CPUs that are 3-5 times more powerful than competitors. For applications like SAP hosting that require extremely high performance and low downtime, these features are ideal.


  1. There are a good range of AS/400 options available.  

    From inexpensive, entry-level systems to high power, massively redundant servers for larger enterprise users, to scalable models for ever-expanding data centers. The IBM iSeries also support multiple operating systems, including AIX, IBM i, SUSE and RedHat Enterprise Linux.


  1. Moving away from IBM Power Systems is not worth the expense.  

    IBM Power Systems have a higher price per core than competitors, but their cores are also much more powerful. For example in a recent presentation, IBM showed a price/performance edge for Power Systems LC machines over Intel Proliant, in both single and dual-socket machines.Keep in mind, this is a test run by IBM, and there are no absolute numbers for performance, since it depends on architecture and workload. Still, at the very least this shows that the IBM AS/400 is priced similarly to competitors. Any price savings gained by switching hardware will be dwarfed by the expense and disruption of moving to another platform — especially with the availability of cloud solutions.
