• New System z15 Mainframe Takes The Heat Off Power Systems

  September 16, 2019 Timothy Prickett Morgan

  I don’t know if many of you work this way, but sometimes I have to say things out loud and follow that train of thought before I decide it is a good, bad, or neutral idea – or any of the different gradations in there and beyond these from absolutely wonderful on one end to impossible or worse yet impossible on the other end. It is a kind of branch prediction, and like modern processors for the past two decades, it is subject to Meltdown speculative execution vulnerabilities.

  (That right there was a nerd joke. I think. Maybe. . …

• What Open Sourcing Power’s ISA Means For IBM i Shops

  August 26, 2019 Timothy Prickett Morgan

  Due to a conflict with a prior engagement at the Hot Chips conference, where IBM unveiled some of the aspects of the impending Power9′ processor that will prototype some ideas about memory subsystems that will appear in the future Power10 chips, we were not able to attend the OpenPower Foundation’s developer summit in San Diego last week. But IBM kept us in the loop, and we were intrigued to learn that Big Blue was open sourcing the instruction set architecture, or ISA, of the Power processors.

  This step is perhaps an inevitable one, given Big Blue’s desire to make the …

• Big Power News On The Horizon, And Some Other Stuff For Now

  August 19, 2019 Timothy Prickett Morgan

  We are awaiting a bunch of things coming out of Big Blue with regard to the Power Systems line, but the engineers are always tweaking the product line to meet customer demand even after things have been shipping for a while. So it is with the “Fleetwood” Power E980 system that IBM debuted last summer using the “Cumulus” 12-core, heavy thread variant of the Power9 processor family and the Enterprise Pool CPU capacity pooling software that runs on enterprise-class Power Systems iron.

  But before we get into all of that, a reminder of what we are expecting to see from …

• Setting The Stage For The Next Decade Of Processing

  August 12, 2019 Timothy Prickett Morgan

  It is no secret that Moore’s Law is causing all kinds of grief with chip designers working in all parts of the IT stack. It was bad enough to run out of clock scaling when Dennard Scaling stopped, and the industry has done a great job in making processors more parallel and allowing for them to offload processing to various kinds of accelerators, either on the die, in the package, or in the chassis over high speed interconnects. But even this is running out of gas as processors keep pushing up against the reticle limits of lithography machines because the …

• Power Systems Keeps Growing Against A Tough Compare

  July 22, 2019 Timothy Prickett Morgan

  This time last year, Big Blue was just starting to ship Power9-based systems for the “Summit” and “Sierra” supercomputers built for the U.S. Department of Energy’s Oak Ridge National Laboratory and Lawrence Livermore National Laboratory, and that gave the Power Systems line a revenue bump through the third and fourth quarters of last year. There is no such big deal this year, although IBM has sold a baby version of these machines – if you consider the 25 petaflops “Pangea III” supercomputer small – to European oil and gas giant Total.

  That deal with Total surely helped IBM make its …

• IBM i Roadmap Promises A Long Ride, Few Bumps

  June 10, 2019 Timothy Prickett Morgan

  It would be hard to find a group of enterprise IT shops that are more conservative – meaning averse to risk – than the IBM midrange. Arguably, IBM System z mainframe shops are even more risk averse, but perhaps it is a matter more of scale than degree. In the average IBM i shop, one person – or maybe a handful of people – is keeping risk at bay, while in a mainframe shop there could be dozens or hundreds that are trying to steer the ship without rocking the boat.

  Every now and then, Big Blue publishes an IBM …

• IBM Gives A Peek Of The Future At POWERUp 2019

  May 20, 2019 Timothy Prickett Morgan

  It would not be a COMMON, or even a POWERUp, conference without some glimpse into the future by IBM to give customers of its Power Systems line a sense of what lies ahead near the horizon. By doing so, Big Blue can provide comfort to customers that it is working on future technologies and services without revealing its hand too much to competitors.

  Steve Sibley, vice president of offerings for the Cognitive Systems division, which is the part of IBM that makes and sells Power Systems iron, participated in the opening session of the POWERUp 2019 conference in Anaheim on …

• Power Systems Bucks The IBM Trend And Grows

  April 24, 2019 Timothy Prickett Morgan

  The Power Systems business continues to grow, and that is good news for all IBM i shops, particularly for those of us who actively want for there to be boisterous competition in server processors and systems architecture. It comes as no surprise that we think Big Blue still has much to offer when it comes to engineering systems that provide real differentiation in the market. The ongoing growth of Power Systems – maintaining the happiness of the substantial IBM i and AIX customer bases and expanding the Linux base – is what is required for IBM to continue to make …

• Rebuilding The Bottom Of The Pyramid

  March 25, 2019 Timothy Prickett Morgan

  In last week’s issue of The Four Hundred, we told you about how Big Blue had extended the life of the Power8-based entry Power S812 Mini, announced on Valentine’s Day last year specifically to give entry IBM i shops a cheaper alternative than buying the Power S814 or Power S824. It seems to me that IBM needs to do some rejiggering of the way it bundles and prices this entry machine to get the installed base of customers using vintage hardware and operating systems to get current and stay there.

  We are under the impression that the number …

• Entry Power S812 Gets A New – But Still Short – Lease On Life

  March 18, 2019 Timothy Prickett Morgan

  Despite the fact that Moore’s Law increases in performance in CPUs have been slowing for years, for many customers, the growth in the throughput performance of processors as more cores and threads are added to a Power9 chip have outstripped the capacity growth requirements for many IBM i shops. For many of these customers, a single core Power7, Power7+, or even Power8 processor did the trick just fine, and is better suited to their needs than an entry Power9 machine with just one core running IBM i.

  We would argue – and have argued many times – that what IBM …
