what-is-as400-ibm-iseries-1-e1466527401462The IBM AS/400 is another name for the IBM Power Systems server line, started in the late 1980s. Technically, AS/400 is the name of the first generation, and the computer is now called the IBM iSeries, but many veteran users prefer the former term, or use the terms interchangeably.

 

The IBM AS/400 is designed to provide extremely high redundancy and uptime. It is traditionally run on-premise, using one of three mature operating systems, optimized for the architecture: OS/400 and AIX. More recently, companies have benefited from IBM iSeries Cloud hosting and additional OS options.

 

Expert Insight: Curtis Gaska, Solution Architect

With the growth of cloud computing, some people have written IBM Power Systems off as a legacy on-premise solution, and the high cost of the hardware dissuades many newer organizations from considering them. But when one hour of downtime can result in $1 million in lost productivity, many older companies — particularly in manufacturing — prefer to stick with the IBM AS/400 architecture they trust. Additionally, the cost and complexity of switching to another solution is hard to justify.

 

How Does IBM Power Systems Support ERP?

SAP Business Suite on HANA®, S/4HANA and other ERP landscapes are resource intensive. IBM Power Systems CPU cores are 3-5 times more powerful than competitors, meaning a given use case will require fewer CPU cores. That means simpler physical architecture and fewer things to go wrong.

 

IBM Power Systems is now offering multiple levels of servers, from consumer-grade servers with little redundancy, to the enterprise series which is redundant everywhere. This provides affordable options for smaller businesses, and allows organizations to cut CapEx on development and QA, while providing the necessary reliability in production environments. However, an increasing number of organizations are moving from on-premise IBM to the enterprise cloud.

 

What Can iSeries/AS400 Cloud Hosting Do For My Organization?

It’s difficult to find expertise for IBM Power Systems, which poses a challenge for companies as older experts retire. Yet, transitioning away from the IBM AS/400 is complex, pricey and disruptive. IBM AS/400 cloud hosting allows companies to stay with the system they trust, while reaping the benefits of the cloud.

 

Moving to a managed private cloud or hybrid environment lets IBM AS400/iSeries businesses cut CapEx and TCO, since the hosting partner pays for hardware, administration and security tasks. It also provides added flexibility, as organizations are able to scale up more quickly and with less disruption than they can with an on-premise solution.
