• The NUMA NUMA [Song] Tax

  October 1, 2018 Timothy Prickett Morgan

  When you have a wafer of chips, at least in theory all of the transistors cost the same on the wafer. But sometimes, when transistors perform certain functions, they are worth more. And in some cases, such as the electronics that enable the coupling of multiple cores on a die across a shared L3 cache or that allow the ganging up of processors across multiple sockets that allows for larger and shared main memory for applications to run in, those circuits are worth a lot more.

  This lashing together of compute components across shared memories – Non-Uniform Cache Access, or …

• Advice For The IBM i Shop Buying X86 Servers

  October 1, 2018 Timothy Prickett Morgan

  We spend a lot of time at The Four Hundred talking about the Power Systems servers and the IBM i platform, but it we also keep a keen eye on what is going on in the rest of the IT world, particularly when it comes to alternative server hardware and transaction processing and data analytics platforms. There are many, many ways to skin the cats that are the backbone of the business.

  Ok, so that was a bad metaphor. It happens. Like a line of bad code.

  Anyway, it is not lost on us that somewhere around 95 percent of …

• IBM’s Own Positioning Of Power Systems Revealed

  September 24, 2018 Timothy Prickett Morgan

  We don’t get a lot of data about how the Power Systems business is doing out of Big Blue these days, and we get even less, in terms of specifics, about the markets that IBM is chasing and how well or poorly it thinks it is doing in this regard. We get a snippet here and there from the quarterly results, we get some insight from the quarterly market trackers from IDC and Gartner, but not much else.

  Digging around through some documents relating to the Power9 rollout, we stumbled across a few interesting charts that gives us at least …

• New Option for 24/7 IBM i Monitoring

  September 19, 2018 Alex Woodie

  It’s important to keep one’s eyes on IBM i server metrics in order to nip problems in the bud. But hiring a night-shift operator can be expensive, and moving your applications to a private cloud might not be feasible. A third option was presented last week by Data Storage Corporation in the form of IBM Power Monitor 24, a new service that promises to provide continuous 24/7 monitoring of client’s IBM i servers.

  Like all cloud service providers, Data Storage Corporation invests in systems monitoring and management. After all, if you’re running critical IBM i servers on behalf of clients, …

• Weak Internal Security Causes Weak External Security

  September 10, 2018 Dan Burger

  Editor’s Note: Our dear friend and colleague, Dan Burger, passed away in August. We grieve. The last story that Dan worked on was about long-time security expert, Pat Botz, joining HelpSystems, the conglomerate that focuses on systems management, monitoring, security, high availability clustering, and performance management for the IBM i platform, along with a bunch of tools for complementary AIX and Linux platforms.

  Botz goes way back in the computer industry. He wrote the Basic compiler and CAD tools for Control Data supercomputers and then lead the development of CAD tools for its AIX workstation line three decades ago. He …

• IBM Showcases New Crop of ‘Fresh Faces’

  September 10, 2018 Alex Woodie

  For a computer platform to remain vital, it must have a constant stream of new arrivals. This is just as true for IBM i, which has struggled to retain relevance in an increasingly homogeneous IT world, as it is for every other platform. But give kudos to IBM and its latest batch of “fresh faces” that highlight the fact that millennials are finding their way to IBM i and Power.

  While nobody is claiming that younger folks are knocking down the door to get onto IBM i, there nevertheless appears to be a solid group of individuals from the less-than-40 …

• HelpSystems Nabs MPG for Performance Management

  August 27, 2018 Alex Woodie

  Midrange Performance Group, the Boulder, Colorado-based provider of capacity and performance management software for IBM i, is the latest software vendor to call it quits and join up with HelpSystems. It was HelpSystems first acquisition of the year and 20th since 2006.

  For decades, Midrange Performance Group, (MPG) has been one of the most trusted names when it comes to capacity planning and performance management for IBM i and the midrange servers that preceded it. If you want to know how your workload would run on a new Power Systems server from IBM, then you could find out using …

• IBM Readies Big Iron With “Cumulus” Power9 Chips

  July 30, 2018 Timothy Prickett Morgan

  The Power Systems lineup has been updated top to bottom on single-socket and dual-socket machinery based on the “Nimbus” variants of the Power9 chip, which sport up to 24 cores per die and have up to four threads per core. These Nimbus chips are used in all kinds of machines, including those that can run IBM i, either alongside AIX or Linux using the PowerVM hypervisor or in what is made to look like a bare metal IBM i setup but which is really a PowerVM machine with one partition. (Shhhhh.) The Nimbus processors are also deployed in …

• RPM And Yum Are A Big Deal For IBM i. Here’s Why

  July 18, 2018 Alex Woodie

  By now you’ve probably heard about Yum and RPM, the new processes that IBM will use to deliver open source software to IBM i customers. But you may have questions about how the process works, and what the benefits will be. IT Jungle talked with IBM’s open source guru Jesse Gorzinski to get the low down on why the new tech is so important to the platform.

  RPM, which stands for Red Hat Package Manager, is a piece of software created more than 20 years that allows customers in that Linux community to more easily distribute and install the various …

• IBM Tweaks Memory And I/O For Entry Power9 Iron

  July 16, 2018 Timothy Prickett Morgan

  The summer is usually pretty quiet in IBM i Land, and this one is no exception. But things do still happen, and it is our job – and we like our job – to keep you informed of things when they do.

  On July 10, while IT Jungle was away on summer break, Big Blue did some tweaks and changes for various elements of the entry Power9 machines that started rolling out this year. These are all little things, but as usual, the little things can add up.

  In announcement letter 118-058, IBM has interestingly announced a new 8 …
