• 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 …

• IBM i Subscription Pricing Comes To All Power9 And Power10 Iron

  February 20, 2023 Timothy Prickett Morgan

  Big Blue has been gradually “cloudifying” the packaging and pricing of its Power Systems hardware and IBM i software stack as an alternative to buying hardware outright and acquiring perpetual licenses to the operating system and pay Software Maintenance. Subscription-based pricing came to hardware and software for the Power10-based Power S1014 server running IBM i 7.5 last year, and now IBM i subscription pricing is more widely available.

  As outlined in announcement letter 223-030 on Valentine’s Day last week, IBM i subscription pricing is now available on all Power9 and Power10 servers, top to bottom, and on the four current …

• A Hodge Podge Of Power Systems Stuff

  February 20, 2023 Timothy Prickett Morgan

  Sometimes Valentine’s Day falls on a Tuesday and ends up being a kind of lightweight Power Systems announcement day. That happened last week as IBM’s top brass in the Power Systems division discussed the priorities for the Power Systems line in 2023, which we covered in the top story in last Wednesday’s issue, and the subscription-based pricing for IBM i on all Power9 and Power10 machines, which we covered in this week’s top story.

  There is always some other stuff that IBM does on Power Systems announcement day, and February 14, 2023, is no exception.

  Announcement letter 120-017 has …

• The IBM i Power10 Upgrade Cycle Forecast Looks Favorable

  February 6, 2023 Timothy Prickett Morgan

  As we talked about last week in going over IBM’s financial results for the fourth quarter, the Power Systems business increased its revenues by 6.5 percent in 2022 thanks to a Power10 upgrade cycle that started in the fall of 2021 with high-end machines and built momentum in the summer of 2022 as the entry and midrange Power10 machines were delivered in the market.

  In general, IBM tells Wall Street to expect that its overall Infrastructure business group will have flat revenues, with some quarters up during the beginning of an upgrade cycle and down at the end of it. …

• Thoroughly Modern: How To Optimize IT In 2023

  January 16, 2023 Jeff Swartz

  It should be no surprise to anyone that applications running on IBM i are business critical. In many cases, these crucial systems keep the business alive day-to-day. Working with organizations around the globe, we are seeing a lot of activity happening in the IBM i space to optimize operations and put in new workload models. Many IT organizations are looking at upgrading. This includes implementing tech refreshes and moving to Power10 systems.

  Now is the time really to think about what the ideal model is for where to run which applications.

  Historically, when companies looked at infrastructure upgrades, they would …
