Because the System i can run at redline speed all day long . . .
Weathering two decades of industry and technology changes, including a few adjustments to its name, the AS/400 turned 20 on June 21. IBM is holding a celebratory event in Rochester, Minnesota, today, with representatives from COMMON and a handful of customers, some of whom won a trip to Rochester to help celebrate the milestone. What a milestone it is! Last week I spoke with Ian Jarman, IBM's manager of Power Systems software, who expressed a few interesting aspects of the 20-year-old system that are worth sharing. Here are some snips:
Customers First
"It's very appropriate through the event to recognize that although this is an anniversary of a system and a technology, more than anything else it's an opportunity to reflect on the unique community that the AS/400 spawned of loyal and passionate customers around the world. We want to recognize the community of ISVs and Business Partners who made this the marketplace what it is today," Jarman said.
Six-Figure Performance Improvements
When it comes to technology and performance, quite a lot has changed since IBM introduced the original AS/400. IBM has announced the Power 595 64-way behemoth, but it won't be available with IBM i until September.
"The original AS/400 B10 had a CPW rating of 3. If we look at the 595, it has a CPW rating of 300,000. So it's 100,000 times more powerful than the original AS/400, which is quite an incredible growth in terms of technology," Jarman noted.
"Equally important to us and to our customers is the fact that applications written on the original AS/400 or even on the 36 or 38 can still run today without recompilation. So we've managed to maintain the promise of application compatibility through the unique architecture of the system all these 20 years," he added.
Case in Point
"When we made the move to 64-bit in 1995, a lot of people were excited and interested in that, and as it turned out, that was the key point which demonstrated that the AS400 architecture was indeed something special and unique in the industry because that change really brought the AS400 forward -- unlike our competitors such as DEC, Wang, and Data General, who weren't able to overcome technology changes in the industry," Jarman explained.
"From a technology point of view, when we look back 20 years, the AS/400 architecture has delivered the ability to overcome technology changes and continue to run applications unchanged. That's why I think you can look to the future with great confidence because that same architecture is what's brought us to Power Systems and is allowing us to take advantage of new technologies today, such as blades and so on, and is allowing us to take our customer community into the mainstream of IBM and the customer community going forward," he said.
Coming Back to Community
"Probably even more important is to recognize that there is something special about the community of customers, Business Partners, and ISVs that has grown around the platform," Jarman noted. "When you step back and look at other architectures and other systems, there's something very special here. The AS/400 was a catalyst for software houses that became ISVs and a different approach to marketing through Business Partners instead of directly from IBM -- there were a whole series of changes the system spawned way beyond the technology itself."
