• The Performance Impact Of Spectre And Meltdown

  March 12, 2018 Timothy Prickett Morgan

  We have been waiting to see what impact on performance the Spectre and Meltdown speculative execution patches, which plug some security vulnerability holes that search engine giant Google discovered last summer and made public in early January, would have on Power Systems iron running the IBM i operating system.

  Now that Big Blue has published the first edition of the Power Systems Performance Report that includes the new “ZZ” Power 9-based systems, we not only get a sense of the relative performance of the “Nimbus” Power9 chip for entry servers. We also can figure out the performance impact of the …

• Drilling Down Into The New Power9 Entry Servers

  February 19, 2018 Timothy Prickett Morgan

  In last Wednesday’s issue of The Four Hundred, we gave you a high-level overview of the six new Power9 entry servers, code-named “ZZ” by IBM, as well as an initial pass on the changes that came with the latest Technology Refreshes for IBM i 7.2 and 7.3. If you haven’t read these, please do, because they give you information on IBM’s strategy with regard to the Power9 iron and the IBM i platform.

  In this issue, we are going to drill down into the six new Power9 systems, taking particular care with the single-socket Power S914 and dual-socket Power …

• IBM Readies Mainstream Power9 Iron For Launch

  February 5, 2018 Timothy Prickett Morgan

  The natives are getting restless, as my parents used to say when we were getting hungry. And the IBM i and AIX bases are definitely getting restless to know what Power9 iron that will be able to run Big Blue’s own operating systems in conjunction with the PowerVM server virtualization hypervisor. They also want to know if IBM is going to give customers a big improvement in price/performance compared to Power7+ and Power8 machines that are still widely available in the channel.

  In short, they want to plan their future, and after four years of waiting, it is time.

  IBM …

• 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 …

• IBM’s Systems Group On The Financial Rebound

  January 22, 2018 Timothy Prickett Morgan

  We like to start with the good news here in 2018, and the good news is that IBM had a very good quarter in its systems business, so we can all start breathing a little easier and Hitachi can put that checkbook away because Big Blue ain’t going to be selling off its System z and Power Systems business any time soon.

  (We are joking there. We think. . . . and hope.)

  In the final quarter of 2017 ended in December, the mainframe saw sales shoot up 71 percent thanks to the System z14 refresh that started in …

• Update On The Spectre And Meltdown Patches For Power

  January 15, 2018 Timothy Prickett Morgan

  When it comes to the Spectre and Meltdown speculative execution security vulnerabilities that hit as the new year was getting going, the important word to ponder is “mitigated.” Everyone is talking about mitigating the issue, but no one is using the word “fixed.” As we discussed last week, one of the two types of Spectre vulnerabilities – the Variant 2 known as branch target injection – is particularly tricky to hack and to fix, so IT vendors are choosing their words very carefully.

  The odds were that unintended consequences for such a low-level fix will occur, so you can …

• 2017: An IBM i Year In Review

  December 13, 2017 Alex Woodie

  It’s mid-December, which means it’s time to look back upon 2017 and reminisce on the biggest stories of the year for IBM i and the overall midrange community. From a pair of Technology Refreshes and the scheduled demise of IBM i 7.1 to acquisitions and security breaches, there was a lot to take in.

  It all started off innocently enough in…

  January

  IBM has had a good run of not changing the name of the platform. In fact, it hadn’t changed the name since 2008, giving it a line of uninterrupted starts that even Giants quarterback Eli Manning could appreciate. …

• Counting The Cost

  November 27, 2017 Timothy Prickett Morgan

  We are strong believers in being thorough with both the technical and economic analysis of platforms. In the absence of a lot of performance and pricing information on Power Systems iron, we are always looking for ways to help IBM i shops try to figure out what to do when they are thinking about upgrading a machine or just tossing out the old one and buying a new one.

  IBM isn’t shipping Power9-based machines that can support IBM i as yet, and it is not expected to do so until early next year. But in the meantime, Big Blue wants …

• IBM Expands Flash Drives For Power8 Iron

  November 27, 2017 Timothy Prickett Morgan

  Back in October, IBM announced a new lineup of small form factor disk drives with 1.8-inch and 2.5-inch form factors as well as updates for 2.5-inch flash drives that were a little bit on the beefy size. We suspect that these drives were intended to be co-launched with Power9-based servers, as well as some new, skinnier flash drives that were announced just before the Thanksgiving holiday in the United States.

  On November 21, in announcement letter 117-108, Big Blue rolled out the new 2.5-inch flash drives that are based on 3D NAND flash memory and are rated at …

• More On That Power8 Core Activation Deal

  November 13, 2017 Timothy Prickett Morgan

  In days gone by, which unfortunately I remember very well, it was not that difficult for any of us to find out what the pricing on every single piece of hardware and software was that comprised an IBM system. The difficulty with IBM’s very sophisticated pricing databases was reckoning how the many pieces fit together to build a system.

  Pricing information for Power Systems iron is a bit harder to come by these days, and as far as I know the pricing databases that I had access to for more than two decades were re-routed to configurators that could only …
