• Guru: IBM i Experience Sharing, Case 3 – When Performance Issues Come From Without

  April 4, 2022 Satid Singkorapoom

  When I started my IT career 35 years ago, it was in the “centralized” universe that originated from the mainframe model. All core application codes ran in one — and only one — big iron that all users accessed with “dumb” terminals devoid of any GUI. Problem solving in AS/400 systems was frequently straightforward and not time consuming because most cases were anything but elusive.

  But the contemporary IT infrastructure universe has evolved into a big onion, with layers that we must peel while troubleshooting. I often find myself having to address a problem in multiple layers, and it no …

• The State Of The IBM Base 2022, Part Three: The Rusting Iron

  March 28, 2022 Timothy Prickett Morgan

  In the past several months, we have been drilling into the results of the annual IBM i Marketplace Survey that HelpSystems does every fall and then reports on each January. We have been taking our time going through the results, and in a number of cases we have been doing our own spreadsheet magic on top of the raw data to provide what we think is better information that describes the current state of the IBM i base.

  In our first story, we talked about the distribution of operating systems over time, spanning from the 2015 report to the …

• Yet More Trimming In The IBM Power Systems Catalog

  March 28, 2022 Timothy Prickett Morgan

  It is hard to say what is really happening at this point, but either IBM has simply run out of features for Power8 and Power9 servers, it can’t get anyone to manufacture any more of them, or it simply wants to use every means it can to get the market ready to move to Power10 machines when they come out in May or June.

  Perhaps it is a bit of all three, eh?

  In announcement letter 922-018 last week, IBM said that effective on March 22 it was no longer selling the RISC-to-RISC data migration feature #0205 for the Power …

• Talking IBM i Shop With New Power Systems GM Ken King

  February 7, 2022 Timothy Prickett Morgan

  Every new general manager of the AS/400 division and its successors all the way up to the current Power Systems division – which hopefully is no longer called Cognitive Systems in the financials but nowhere else – inherits a unique configuration of that business in time and space and after one, two, or three years leaves it in another configuration.

  In all of our years of writing The Four Hundred, we have made an effort to get to know each and every one of them. Last July, ahead of the spinout of the Kyndryl managed services business in November, …

• 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 …

• Balancing Supply And Demand For Impending Big Power10 Iron

  August 9, 2021 Timothy Prickett Morgan

  It is always an exciting time when Big Blue is rolling out a new processor generation – well, with the exception of the Power6+, which IBM did not really talk about at all and tried to pass off as a Power6 until I figured that out. And I have to admit, IBM used the Power6+ architectural tweak and a refinement of the 65 nanometer chip manufacturing process (as opposed to an expected 45 nanometer process shrink) to still cram two whole processors into a dual chip module to radically expanding the throughput performance per socket, and it was impressive …

• Time To Design – And Deliver – The Application System/360

  July 19, 2021 Timothy Prickett Morgan

  The stupidest thing IBM ever did was create a system other than the System/360. It had the perfect name and it had the right idea of creating a compatible line of small, medium, and large enterprise systems that ran a widening variety of operating systems and workloads, often concurrent on the same machine. The AS/400 really should have been the third generation of System/360 machines, and the systems today would be somewhere around the sixth of seventh or even tenth generation, however you want to think about it.

  Every decade or so in IBM’s history, it has tried to converge …

• 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 …

• Thoroughly Modern: Clearing Up Some Cloud And IBM i Computing Myths

  June 14, 2021 Timothy Prickett Morgan

  We hear a lot of talk about cloud these days, but who is walking the walk? The coronavirus pandemic made a lot of companies take a hard look at how they were doing business, and hardware wasn’t excluded from this conversation. Businesses are now saying, with so many cloud options available, where and how can they start getting their feet wet?

  We certainly all know that the IBM i community is dramatically different from most other platforms in the IT space, and has been since Day One. For household names such as Amazon Web Services, Microsoft Azure, and Google Cloud, …

• 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 …
