• The Herculean Task Of Applying Spectre/Meltdown Patches

  October 1, 2018 Timothy Prickett Morgan

  The Spectre and Meltdown speculative execution vulnerabilities are, as our resident chief technology officer and author of the weekly IBM i PTF Guide, Doug Bidwell, is fond of saying, the gift that just keeps on giving.

  We had the shock of finding out in January that there were vulnerabilities in all processor architectures that use speculative execution in their instruction chewing engines – that means all existing processors, by the way. There are none that do not use this very useful architectural feature. And then we had the wait to see what the industry would do to patch these …

• The IBM i Base Is Ready To Move On Up

  January 22, 2018 Timothy Prickett Morgan

  Even the most eager hyperscaler or cloud builder in the world has to let a server sit in place, running workloads, for at least three years to get good value on the dollar spent, and in many cases, machines are repurposed to be in the fleet for longer than that. And no company can accept the risk of changing all machines at the same time, for obvious reasons other than cost, because such a change could be very disruptive to any business. Enterprises tend to have less spare iron and fewer techies, and so they are even more conservative, and …

• More Power7 And Power8 Features To Bite The Rust

  October 30, 2017 Timothy Prickett Morgan

  The Power Systems catalog just keeps getting skinnier as the Power9 systems launch in early 2018 keeps getting closer. Ironically, as IBM pulls the plug on older Power Systems machines and their features, it is a good indication that Big Blue really is preparing the way for Power9. It is also a way to get customers who have no intention of spending on Power9 iron to buy something on their older gear before the features go away.

  I saw a new abbreviation in announcement letter 917-177, which came out on October 24, and that was LTB – short for …

• IBM Inks In End Of Support For Power6 And Power7 Iron

  September 25, 2017 Timothy Prickett Morgan

  In case you didn’t notice it, IBM is getting ready to embark on a new generation of systems, based on its “Nimbus” and “Cumulus” Power9 chips.

  When new gear is entering the product catalog, IBM has a few tools to help encourage customers to move ahead rather than sitting tight. First, it tends to withdraw the older stuff – in this case systems using Power6, Power6+, Power 7, and Power7+ processors – from marketing. That sends the signal that customers won’t be able to get new processor cards, memory cards, and other peripherals for these machines. Then, IBM can raise …

• IBM Commits To Power9 Upgrades For Big Power Systems Shops

  July 10, 2017 Timothy Prickett Morgan

  While there are plenty of small and midsized shops that make up the majority of installations of Power Systems running IBM i, it is the larger customers – a few hundred really big ones and several thousand pretty big ones – that generate the majority of the revenues for hardware, software, and services for the platform. So what IBM does or does not do to protect the investments of these large customers will affect the smoothness of a product transition like the Power9 one that will start early next year.

  With each generational change, whether it is a baseline processor …

• Taking A New Look At Used IBM i Gear

  April 17, 2017 Timothy Prickett Morgan

  In some ways, we miss the days when OS/400 and IBM i gear was more expensive than it is today. Thanks to considerably larger customer and reseller bases and because hardware was so expensive and, costing something on the order of a few mansions per month to rent or lease or finance, there was a vibrant market in second-hand AS/400 and iSeries equipment.

  But as the base got smaller and systems got cheaper thanks to Moore’s Law improvements on all hardware components except the tin wrapping around them, the market for used equipment became thinner and less orderly. And, perhaps …
