  • IBM i Delivers Sizable Benefits, Forrester Consulting Reports

    June 7, 2023 Alex Woodie

    IBM i shops have firsthand knowledge of the positive characteristics of the platform relative to industry-standard X86 servers. We often hear anecdotes about the platform and share them with you through these pages. But IBM would like to get beyond mere anecdotes and get to some hard numbers on the IBM i advantage. That’s when it turns to Forrester Consulting.

    According to Forrester Consulting’s latest Total Economic Impact (TEI) report, a typical IBM i customer can expect to save about $2.6 million over three years as a result of the IBM i platform’s uptime, productivity, and efficiency. The report, …

  • Power10 Boosts NVM-Express Flash Performance

    June 5, 2023 Timothy Prickett Morgan

    We are always on the lookout for any performance tests that show the benefits of adding flash storage to Power Systems iron, and we found some recently in an NVM-Express flash drive deep drive given by Douglas Gibb’s the I/O product manager for the Power Systems line at IBM during the POWERUp 2023 conference in Denver.

    The presentation that Gibbs gave went through all of the ins and outs of flash storage on Power Systems, including those that use the NVM-Express protocol over the PCI-Express peripheral bus, which offers a direct link between the operating system and the flash storage …

  • Update On Critical Security Vulnerability In PowerVM

    May 24, 2023 Timothy Prickett Morgan

    Earlier this week, we told you about a very serious security vulnerability in the PowerVM hypervisor when running on Power9 and Power10 systems. IBM found the vulnerability itself and immediately set about to patch the vulnerability, which it revealed on May 17 along with patches to firmware in systems that are managed by the Hardware Management Console, or HMC.

    What was not necessarily apparent was that there are plenty of Power Systems customers who do not have HMCs managing their systems and the logical partitions upon them, and this is particularly true of the IBM i installed base, which …

  • Critical Security Vulnerability In PowerVM Hypervisor

    May 22, 2023 Timothy Prickett Morgan

    IBM’s Product Security Incident Response Team (PSIRT) put out a notice on Wednesday, May 17, to inform the Power Systems installed base that there is a very serious security vulnerability in the PowerVM hypervisor. You can see the PSIRT notice at this link and the Security Bulletin: This Power System firmware update is being released to address CVE 2023-30438 at this link. This has a CVSS base score of 9.3, which means it is critical.

    We very rarely see any security vulnerabilities being reported for the PowerVM hypervisor or for the IBM i operating system itself, for that matter, …

  • IBM i PTF Guide, Volume 25, Number 21

    May 22, 2023 Doug Bidwell

    As we report elsewhere in this week’s edition of The Four Hundred, there is a critical security vulnerability in the PowerVM hypervisor when it is running on Power9 and Power10 systems.

    This HIPER/Pervasive patch is described as fixing this: An internally discovered vulnerability in PowerVM on Power9 and Power10 systems could allow an attacker with privileged user access to a logical partition to perform an undetected violation of the isolation between logical partitions which could lead to data leakage or the execution of arbitrary code in other logical partitions on the same physical server.

    The Common Vulnerability and Exposure …

  • The Inevitable Power9 Hardware Withdrawals Begin

    May 15, 2023 Timothy Prickett Morgan

    The high end Power10 machine, the Power E1080, has been out since September 2021 and the rest of the Power10 line was announced in July 2022, so the writing was on the wall for any Power9-based machines the minute that happened.

    The ability for IBM to get, much less sell, Power9 chips even if it wanted to is also somewhat dubious, too. In October 2014, IBM sold off its Microelectronics division to Globalfoundries, itself a spinout of AMD’s foundry business five years earlier mashed up with Chartered Semiconductor and backed by the government of Abu Dhabi. Here’s the complication: …

  • An Update On Power From POWERUp 2023

    April 26, 2023 Timothy Prickett Morgan

    After so many years of not normal, it is comforting to do something to feel normal, like travel to what used to be the COMMON spring user conference and what is now called POWERUp, and in particular POWERUp 2023. (I am only using the official capitalization there because Jenny will change it during edit if I don’t.) I don’t want to leave the hill I live on, especially after so many years of traveling many times a month, but I must say that I enjoyed myself and had my share of boisterous conversations, beer, and food.

    And work, of course. …

  • Disaster Recovery: From OS/400 V5R3 To IBM i 7.4 In 36 Hours

    March 27, 2023 Jason Hardy

    Earlier this year, I wrote an article entitled The IBM Power Trap: Three Mistakes That Leave You Stuck that described how a series of decisions related to how you manage your applications and IBM Power can leave you stuck. A few people reached out to me with questions so I thought it might be appropriate to share a real-life story about one of our customers, we will call them Glass Corp International (GCI), that got caught in this trap and had to be rescued.

    With their busiest weekend of the year just days away, GCI, an Ohio-based company, had all …

  • The IBM i OS Base Is Older Than We Think, But Moving Ahead

    March 6, 2023 Timothy Prickett Morgan

    Hardware upgrades are costly in terms of money and while it is always exciting to get a new system with that “new computer smell” – and you know what we are talking about – at least IBM i operating system and systems software upgrades don’t carry such a high price – provided you are on Software Maintenance and you do proper testing on your software before you make a jump to a new release.

    The other great thing about IBM i systems software is that any given release not only runs on the current new Power Systems hardware at the …

  • 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 …
