This has been an ongoing
argument disagreement in our IBM i and RPG programmer communities for well over a decade: Should IBM have changed the name when the launched the replacement for the old AS/400 computer? Many people using the latest IBM i servers still enjoy calling it "the 400" but the big problem with this is that non-technical people (often management) hear this and then think they are still using the huge old fashioned pre-internet computer system of yesteryear.
A simplified history of The 400:
Hardware: The AS400 was replaced by the iSeries. The iSeries was replaced by the System i. The System i was replaced by the Power System.
Software: Operating system has evolved and been rebranded with each new system hardware upgrade -- from OS400, thru I5/OS to the latest OS called IBM i. That is an internet fact.
I like to describe this as:
Generation 1 - AS400 (running OS400 operating system)
Generation 2 - iSeries (running OS400 operating system)
Generation 3 - System i (running i5/OS operating system)
Generation 4 - Power System (optionally running the IBM i Operating system)
For some hugely frustrating reason, there is still a sizable group of IBM i Software Developers who insist on referring to the latest and greatest IBM i Power machine by the incorrect name of it's twenty year old predecessor. This machine is NOT an AS400. It is not "THE 400". It's not even an iSeries. The AS400 is an old computer system from the last century! The AS400 hardware could not run the modern operating systems we use. The AS400 was invented before the advent of email, before facebook, Hell... it was around before the internet! Calling IBM POWER SYSTEMS an AS/400 is insulting and automatically puts the picture of an old legacy computer system into our users heads. Not good. When a new model of a computer is released with brand new hardware and a different name (to differentiate it from the old model) use the correct name. I just don't understand this resistance against the new machines branding. As I.T. Professionals surely it's the information technology that fires us up. Surely it's the excitement of modern computers that wakes us up every morning? We are all IT Professional, surely that makes us all Star Trek Nerds, which in turn means we all understand that "Resistance is Futile!" ;)
Anyway, back on topic of the AS400 -> iSeries -> System i -> Power System upgrade discussion
Last night, I was reading a frustrating discussion on Linkedin about this very subject. The core of the conversation goes like this
I heard from one of my old customers from the 1990's and my software is still running on their 400 - bloody good machines these iSeries boxes
Cool! But I wouldn't think they are still using the old iSeries hardware. Probably on a more recent IBM Power System running the IBM i operating system
