• Power11 Takes Memory Bandwidth Up To, Well, Eleven

  December 2, 2024 Timothy Prickett Morgan

  Last week, we went over the roadmaps for the future Power11 processor from IBM and its follow-on, the Power Next chip that we presume will be called Power 12 because, you know, history. This week we want to take a little bit of a deeper dive into the Power11 strategy and what this might mean for the systems that Big Blue will be building in the future.

  If IBM’s change in strategy with Power Systems since the Power9 generation has not been obvious to you, it perhaps bears pointing out. In the Power8 and Power9 generations, IBM was trying to …

• The State Of The Power Systems Base 2024: The Systems

  February 5, 2024 Timothy Prickett Morgan

  The foundation of any system is its processor. It is the central processing unit, or CPU, which used to be part of what we called the main frame in a multi-frame system, that ultimately does the calculations that make computing useful. There have always been many things that wrap around this CPU that turn it into a complete system – memory, networking, other kinds of I/O, various levels of storage, all in their own hierarchies. But if you ask someone what kind of system they have, beyond the vendor and the brand, the next bit of data they will …

• The Plus Things Change, The Plus Things Stay The Same

  October 23, 2023 Timothy Prickett Morgan

  Like nearly all of you, I have never read the autobiographical romance novels of Jean-Baptise Alphonse Karr, or read back issues of the satirical Le Figaro newspaper that were nearly two centuries old when Karr was editor of that paper, which is today aimed at the upper middle class and which is still one of the papers of record for France.

  But like nearly all of you, I am very familiar with one of the witticisms that came out of Karr’s pen: “Plus ça change, plus c’est la même chose.” Which translates into American as something akin to: …

• Power10 Systems Get Storage And I/O Enhancements

  October 16, 2023 Timothy Prickett Morgan

  There is a spring-fall cadence to the Power Systems platform from IBM, and so when the second batch if Technology Refreshes come around this time of year, we expect to see some hardware updates, too.

  In recent years, we have been hoping – as always – that there would be a Power8+ or Power9+ processor enhancement around halfway through those processor family cycles, because that usually provides a price/performance kicker. But this has not happened during this generation as it did with the Power4+, Power5+, Power6+, and Power7+ generations. And we intend to put the pressure on IBM for a …

• The Power Systems Base Is A Little Less Rusty

  February 27, 2023 Timothy Prickett Morgan

  Another three years, and another upgrade cycle that can bring about the modernizing of the Power Systems iron that supports the IBM i customer base. Or, more precisely, another four distinct upgrade cycles that customers are on as they move off legacy iron to something more current than what they have.

  What we mean by this is that some customers are stuck on older releases because they are cheapskates by necessity or they have applications that can only run on older releases like OS/400 V5R3, i5/OS 5.4, or IBM i 6.1. Others are stuck on IBM i 7.1. Or IBM …

• IBM Drops Power10 Into Big, Bad Iron First

  September 8, 2021 Timothy Prickett Morgan

  After a long, long wait – it has been nearly four years since the first Power9 machine was launched in the “Witherspoon” Power AC922 supercomputing node back in December 2017 based on the 24-core “Nimbus” Power9 processor and just over three years since the high-end “Fleetwood” Power E980 system debuted with the 12-core “Cumulus” Power9 variant – the first machines out of IBM based on the Power10 processor are being unveiled.

  The expected three-year cadence between processor generations set by IBM a long time ago has worked out almost precisely for high-end Power Systems shops, with today’s launch of the …

• The Other IBM Big Iron That Is On The Horizon

  August 23, 2021 Timothy Prickett Morgan

  The Hot Chips conference is underway this week, historically at Stanford University but this year as was the case last year, is being done virtually thanks to the coronavirus pandemic. There are a lot of new chips that are being discussed in detail, and one of them is not the forthcoming Power10 chip from IBM, which is expected to make its debut sometime in September and which was one of the hot items at last year’s Hot Chips event.

  The one processor that IBM is talking about, however, is the “Telum” z16 processor for System z mainframes, and unlike …

• IBM Versus GlobalFoundries: A Lawsuit Instead Of The Power Chips Planned

  June 14, 2021 Timothy Prickett Morgan

  Last week, IBM took its former foundry partner, GlobalFoundries, to court in a lawsuit that alleges, in essence, that the company promised to deliver Power9 processors based on 14 nanometer technologies and Power10 processors based on 10 nanometer technologies and had some issues with the former and never delivered on the latter.

  Not only that, IBM’s lawsuit says that it never released GlobalFoundries from its from its promise to deliver a 10 nanometer chip, and when the company promised to shift to 7 nanometer technologies, IBM in good faith worked on developing Power10 chips for these processes and spent at …

• In The IBM i Trenches With: Computer Plus

  March 29, 2021 Timothy Prickett Morgan

  Welcome to a new series in The Four Hundred called In The IBM i Trenches.

  We spend a lot of time talking to people at IBM and at the key suppliers of systems software, application software, and development tools for the IBM i platform. But the ecosystem is a lot bigger than these players. There are thousands of resellers, each serving tens to hundreds to sometimes thousands of customers, depending. There are suppliers of third party maintenance as well as technical support and all kinds of programming and system management services. And there are an increasing number of hosting …

• Max Thread Room

  September 28, 2020 Timothy Prickett Morgan

  For a lot of organizations that buy servers and create systems out of them, the overall throughput of each single machine is the most important performance metric they care about. But for a lot of IBM i shops and indeed even System z mainframe shops, the performance of a single core is the most important metric because most IBM i customers do not have very many cores at all. Some have only one, others have two, three, or four, and most do not have more than that although there are some very large Power Systems running IBM i. But that …
