• Direct Attached Storage Gets Massive NVM-Express Expansion

  April 12, 2023 Timothy Prickett Morgan

  The storage area network – a giant wonking storage server with lots of lossless Fibre Channel switching between servers that share access to virtual storage partitions – has been around for several decades now. And despite all of the talk of its ubiquity, and usefulness in driving up storage utilization across a bunch of servers and therefore helping drive down the cost of that storage while also enhancing its manageability and shareability, for many IBM i shops, using directly attached storage is what they want to do.

  There are reasons for this, of course. In many cases, the IBM i …

• Tweaks To The Power Software Stack, And Red Hat Gets Easier

  April 12, 2023 Timothy Prickett Morgan

  Whenever there are Technology Refreshes for the IBM i operating system, its database, and the related systems and development tools for IBM i, you can bet Elon Musk’s last dollar that there will also be nips and tucks, and sometimes more significant changes, to the adjunct software that runs on Power Systems iron. Such as the PowerVM server virtualization hypervisor, the PowerVC implementation of the OpenStack cloud controller, the PowerSC security tools, and other things.

  And indeed, as part of the April 11 announcements, IBM has tweaked this Power Systems stuff. This is not one of the big ones, as …

• Four Hundred Monitor, April 12

  April 12, 2023 Jenny Thomas

  Artificial intelligence is not a new concept to our readership. But in recent weeks, we’ve seen a flurry of activity regarding AI, and frankly even we are a little worried. Imagine if some computer sucked up every article IT Jungle editor Tim Prickett Morgan ever wrote to create a digital TPM? It’s hard to believe even the most clever ChatGPT could do more than a weak imitation, but still a frightening thought that any of us might be so easily replaced. The Top Stories this week are heavily focused on AI, and we give you a sampling of what’s happening …

• Entry Servers: IBM i Versus Windows Server, Redux

  April 10, 2023 Timothy Prickett Morgan

  No comparison between similar but different things is ever perfect. It is the nature of language, constructed of similes and metaphors, as well as science, which speaks in generalities but craves ever-finer precision. It is no different when trying to compare different system platforms, which we do quite often around here at The Four Hundred and have for three and a half decades.

  The comparison between the Power S1022s running IBM i and a Dell PowerEdge R7515 running Windows Server and SQL Server, which we did last week, needed some refinement, I learned from an intrepid reader who reminded …

• Performance Management: A Personal History, And Turning A New Page

  April 10, 2023 Doug Mewmaw

  The term “performance management” is broad, comprehensive, and uniquely personal depending upon the system, situation, and experience of the user defining it. I stumbled into the world of performance management early into my career, without even knowing it. As I reflect back on my career, it is also natural to reflect upon the history of performance management.

  I thought this reflection might be interesting to not only the old pros out there but also the new guys just coming into the industry. I have been fortunate to be on an interesting journey, and one that is about to change not …

• Wanted: Code For IBM i Contributors

  April 10, 2023 Alex Woodie

  If you have a knack for IBM i development and a passion for open source, then Liam Allan, the creator of the Code for IBM i project, would like a word. That’s because Allan, faced with large demands from his day job at IBM, is seeking help from the IBM i community to develop and maintain the Code for IBM i project.

  “Myself and the core team (three other people) are a little overwhelmed by our workload, balancing jobs and maintaining a large project is tough,” Allan wrote in a March 9 blog post on Ryver, the Web-based forum …

• Technology Refreshes, And Maybe Some Hardware Tweaks, Coming This Week

  April 10, 2023 Timothy Prickett Morgan

  We have heard through the rumor mill for weeks that we should expect Technology Refreshes for the current releases of IBM i sometime this week, and Tuesday being a traditional announcement day for Big Blue, it is reasonable to assume that this will happen on April 11. With history as a guide, it is reasonable to also assume that there will be some kind of tweaks to the Power Systems hardware and to parts of the software stack that IBM has on this machines, including but not limited to, IBM i.

  This being the belly of the Power10 hardware cycle, …

• IBM i PTF Guide, Volume 25, Number 15

  April 10, 2023 Doug Bidwell

  It is Spring Break in a lot of places, and also Easter and Passover as we go to press, and so it is not at all surprising that there is not a lot of activity in the IBM i PTF Guide this week. We took the opportunity to retire 7.2 worksheet, check the archives, and, DLB_PTF_04/01/23_B25N14.XLS for the last worksheet. Any changes to V7R2 going forward will be detailed here instead of the Guide.

  There are High Impact/Pervasive tweaks for all currently supported releases – IBM i 7.5, IBM i 7.4, and IBM i 7.3 – and a fix list …

• Stacking Up IBM i On Entry Power10 Iron Against Windows Servers

  April 3, 2023 Timothy Prickett Morgan

  Because of the dearth of commercial benchmarks that are run on IBM’s Power Systems machines these days, it is hard to make direct comparisons between machines based on Big Blue’s Power10 processor and the Windows Server and Linux platforms – generally an X86 system based on a processor from Intel or AMD. But it is not impossible to do.

  And it is an important exercise not because you are thinking of moving off the platform, which of course you are not contemplating, but because by doing this math you can show that it is not really much cheaper to buy …

• Why Modernize Applications? The Reasons Might Surprise You

  April 3, 2023 Alex Woodie

  A wave of interest in application modernization seems to be cresting over IBM i and mainframe shops in the United States and Europe, and it’s having some unanticipated impacts. We’re also getting a better understanding of what’s motivating companies to jump into these potentially risky projects, which is a topic that EvolveWare touched on in its latest report.

  EvolveWare, which develops modernization tools for mainframe and IBM i applications, discussed several aspects of modernization in its report on modernization released last month. Our first take on the report, which is titled The State of Application Modernization 2023, focused …
