• Guru: IBM i Experience Sharing, Case 2 – Dealing With CPU Queuing Wait Time

  March 21, 2022 Satid Singkorapoom

  When we drive our cars, we hope to avoid red lights and traffic jams, because we all hate waiting immobile in traffic. I’m sure that you are aware, fully or subtly, that active jobs in any computer system can encounter wait as well. The IBM i developer team has categorized many types of wait.

  In this article, let’s look at CPU Queuing wait time. Let’s see how we can interpret and address it in a sensible way to resolve poor performance. I’ll try to provide you with a useful approach to wait time analysis using a gloriously useful performance reporting …

• IBM Brings OpenShift Cluster Management Native On Power Iron

  March 14, 2022 Timothy Prickett Morgan

  If you went out to GitHub and grabbed the source code for the Kubernetes cloud controller, you could compile it in C/C++ or set up the runtimes for the Python chunks of it, and you would probably find some Go buried in there and you could the toolchain and get the raw Kubernetes to work on Linux partitions; you might even be able to get it to run natively on AIX, and if you were really clever, you might even be able to get it to run on IBM i.

  But you wouldn’t have very much that was useful given …

• April Fools, Or Not: IBM Raises Power Systems Prices

  February 28, 2022 Timothy Prickett Morgan

  In an inflationary environment with all kinds of parts shortages, it is no surprise when IT suppliers raise their list prices and/or cut back on the depth of their discounts as they negotiate deals. We are certainly in that kind of environment, and we are also on the cusp of new Power10-based entry and midrange server announcements from IBM as well.

  Given all of this, we expected Big Blue to be announcing some price increases on older Power9 iron, which might be in short supply and therefore might be subject to “opportunistic pricing” as too much demand is chasing too …

• The State Of The IBM i Base 2022, Part Two: Upgrade Plans

  February 23, 2022 Timothy Prickett Morgan

  It is always good for the IBM i ecosystem when there are new machines on the horizon with new processors, a lot more performance, and much better bang for the buck. This is, in many ways, what has drive the System/3X, AS/400, and IBM i midrange business forward for more than four decades.

  But you have to admit, the kind of excitement that we used to have in the early years of the AS/400, when performance needs often outstripped what Big Blue – and indeed, any system supplier – could afford, is not prevalent in the IBM i base today. …

• Thoroughly Modern: Taking Charge of Your Hardware Refresh in 2022

  February 14, 2022 Peder Lundblad

  IBM i shops are well known for paying a premium for their systems because they are worth it, but they are also just as well known for hanging onto aging hardware a bit past its prime, which has its own kinds of economic costs in higher maintenance and operational costs as well as the risk of a failure in some key component of the hardware or of having an older operating system release that does not have a key security vulnerability or bug patched.

  IBM does a very good job of keeping hardware technology cycles regular, and so there is …

• 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, …

• Solving The Power9 Dilemma

  February 7, 2022 Jason Hardy

  Purchase hardware, depreciate hardware, and repeat.

  After four years on the market, the Power9 processor is in the process of being replaced by the Power10 chip. Whether you are an early adopter of CPUs or a laggard, the challenge for many companies is the timing of the refresh. As leases on the Power9 machines are expiring, companies are struggling with how to bridge the gap between the end of their current Power9 system lease and the release of the Power10 systems. Their typical options include lease renewals, lease buyouts, or purchasing a new Power9 server, but some companies just want …

• The IBM i Cloud Just Got More Frictionless With Virtual Serial Numbers

  January 31, 2022 Timothy Prickett Morgan

  If the cloud is to be successful, it has to do more than provide a new deployment and pricing model for IT organizations. It has to also maintain and retain some of the important practices in use by the IT department. One of the big disconnections between on premises IBM equipment and capacity sold in the cloud has been the serial number that identifies a machine, which is a kind of birth certificate and Social Security number for each box that comes off the IBM factory lines.

  That serial number is used to identify the machine for technical support purposes …

• DSC Bullish On IBM i Cloud Growth

  January 31, 2022 Alex Woodie

  You may know Data Storage Corporation as the company that provides hosted high availability and disaster recovery services. But the New York company has moved beyond its roots in data storage with its fast-growing cloud hosting business, where it runs hundreds of IBM i environments on behalf of its customers. With the great cloud migration just starting for Power customers, there’s a considerable upside for companies like DSC.

  Data Storage Corporation was one of the first IBM business partners to get into the cloud business. It started building its IBM i cloud in earnest in late 2012, and launched it …

• Building A More Perfect IBM i Cloud On Power10 Iron

  January 24, 2022 Timothy Prickett Morgan

  As we get closer to the launch of the entry and midrange Power10 machines, we can’t help but think about the innovative uses that these machines might be put to. We think, for instance, that these machines could be the foundation of a new generation – and a new kind – of IBM i cloud based on a mix of entry one-socket Power S1021 and two-socket Power S1022, and Power S1024 machines augmented in a very special way with four-socket Power E1050s.

  To one way of thinking, the easiest way to build a big cloud capable of supporting thousands of …
