• Systems A Bright Spot In Mixed Results For IBM

  October 22, 2018 Timothy Prickett Morgan

  It is hard to describe a company that raked in $18.76 billion in revenues and brought $2.69 billion of that to the bottom as limping along. But watching IBM, as revenues declined by 2.1 percent, after many years of gentle declines, and profits off by 1.3 percent, it sure does feel that way sometimes.

  In past years, as Big Blue crested above $100 billion in sales, its growth was limited by its total addressable market among large enterprises that can only get so large, too, as well as by the limits of its imagination for peddling wares to small and …

• 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 …

• IBM i Gets The Big Power9 Iron, But Not The Midrange

  August 15, 2018 Timothy Prickett Morgan

  First of all, let me apologize for not getting to this story last week, but I had a bunch of personal stuff going on and frankly, it is still going on. To eliminate the mystery, I will tell you the big part, which is that I was preparing to get married, then got married, and then tried to take a short honeymoon out in the mountains, and I did not expect for IBM to try to announce the last of the Power9 servers smack dab in the middle of all that.

  But on August 7, IBM did just that. For …

• Pushing The Capacity Envelopes With IBM i 7.3

  April 9, 2018 Timothy Prickett Morgan

  Every piece of systems software has some sort of maximum capabilities reference, and these documents are interesting in their own right to help system administrators, programmers, and database administrators, as they case may be, figure out where they might hit a ceiling in terms of capacity or performance.

  IBM has just published the Availability Maximum Capacities reference for IBM i Version 7 Release 3, which you can take a gander at here. As this reference correctly points out, coming close to the performance limits – or many of them at the same time – can cause outages. In this, …

• 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’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 …

• Advice For The Power Systems Shop That Has To Buy Now

  October 23, 2017 Timothy Prickett Morgan

  Having to buy a new computer as one generation is ending and the new one is not quite yet beginning puts users in a tough spot. Without knowing the feeds and speeds of the system, you can’t compare what you might be giving up if you buy now. And without knowing the price of the new machine, and the current price of its predecessor that you might buy, you can’t tell how hard you have to negotiate if you buy the current model instead of the one that is coming down the pike in a few months.

  IT budgets tend …

• Power9 Big Iron “Fleetwood/Mack” Rumors

  October 9, 2017 Timothy Prickett Morgan

  Sometimes, the universe just hands you a great title, like that one above. As the Power9 platform is rolling out across the field to various launch pads, with entry, midrange, and high-end systems in the works, word always inevitably leaks out about what Big Blue has planned with its future systems.

  In the case of the high-end machines, we are hearing rumors that the current top-end Power E880 and its half-pint Power E870, which went by the code-name “Brazos” within IBM, likely in deference to the river in New Mexico, will be replaced by a machine code-named “Fleetwood,” no doubt …

• The Chatter About Future Power9 Servers

  September 11, 2017 Timothy Prickett Morgan

  In late July, the first of the Power9 systems, the one code-named “Witherspoon” that was designed explicitly to be installed in the “Summit” and “Sierra” clustered supercomputers installed at Oak Ridge National Laboratories and Lawrence Livermore National Laboratory, respectively, started rolling off the production line at Big Blue and into those HPC centers that are funded by the U.S. Department of Energy. It is the beginning, however quiet, of what we expect will be a rolling thunder rollout of Power9 systems in late 2017 and through early 2018.

  Because there have been so many processor announcements in the past …
