• More Vintage Power Systems Stuff Gets The Plug Pulled

  November 4, 2019 Timothy Prickett Morgan

  We are well into the Power9 era and looking ahead to the Power10 and Power11 era, so it is no surprise at all that IBM is looking to streamline its product catalog and empty out its barns of old equipment. In announcement letter 919-139, which somehow slipped our attention two weeks ago on October 22, a whole bunch of Power Systems stuff got the axe, with withdrawal dates ranging from right now until February 2020.

  On October 22, IBM i 6.1.1, with its machine code, will no longer be available for ordering on a slew of machines. This is …

• After Seven Quarters Of Growth, Power Systems Declines

  October 21, 2019 Timothy Prickett Morgan

  The tough compares have hit home on IBM’s Power Systems business, but the good news is that this has happened after seven consecutive quarters of growth for the Power-based server business that Big Blue owns lock, stock, and barrel. Even with this decline, which was quite steep because of the triple whammy of tough compares (more on that in a moment), there is still a healthy underlying Power Systems business that is much better off than the last time it was hit by similar declines.

  Let’s take a look at the numbers for IBM’s Power Systems division and then work …

• Power7 And Power7+ Will Truly Be Dead At The End Of 2020

  October 7, 2019 Timothy Prickett Morgan

  There are five dates that define the life of a piece of software and hardware: When it is announced, when it is generally available, when it is withdrawn from marketing, when service is withdrawn on the product, and when extended service (which is limited and which costs a lot more money than regular service) is dropped and the product is truly done for.

  With software, IBM sometimes provides service, service extension, extended service extension, and even extended-extended service extension. I am not making this up, and yes it sounds like the Monty Python SPAM skit. Take a look:

  As you …

• Power9 Prime Previews Future Power10 Memory Boost

  September 30, 2019 Timothy Prickett Morgan

  Customers who are deploying Linux on Power Systems iron from Big Blue are about to get a very substantial boost in memory bandwidth as IBM is getting ready to launch the Power9’ (that’s a prime symbol, not an apostrophe or a typo, after the 9) processor. As we previewed back in March 2018, the Power9’ chip will feature a substantially upgraded memory subsystem that has a new, faster SERDES signaling technology, normally used for various kinds of system and accelerator interconnect, that has been tweaked to support memory buffers and therefore DDR4 and future memories.

  There is no technical …

• New System z15 Mainframe Takes The Heat Off Power Systems

  September 16, 2019 Timothy Prickett Morgan

  I don’t know if many of you work this way, but sometimes I have to say things out loud and follow that train of thought before I decide it is a good, bad, or neutral idea – or any of the different gradations in there and beyond these from absolutely wonderful on one end to impossible or worse yet impossible on the other end. It is a kind of branch prediction, and like modern processors for the past two decades, it is subject to Meltdown speculative execution vulnerabilities.

  (That right there was a nerd joke. I think. Maybe. . …

• What Open Sourcing Power’s ISA Means For IBM i Shops

  August 26, 2019 Timothy Prickett Morgan

  Due to a conflict with a prior engagement at the Hot Chips conference, where IBM unveiled some of the aspects of the impending Power9′ processor that will prototype some ideas about memory subsystems that will appear in the future Power10 chips, we were not able to attend the OpenPower Foundation’s developer summit in San Diego last week. But IBM kept us in the loop, and we were intrigued to learn that Big Blue was open sourcing the instruction set architecture, or ISA, of the Power processors.

  This step is perhaps an inevitable one, given Big Blue’s desire to make the …

• Big Power News On The Horizon, And Some Other Stuff For Now

  August 19, 2019 Timothy Prickett Morgan

  We are awaiting a bunch of things coming out of Big Blue with regard to the Power Systems line, but the engineers are always tweaking the product line to meet customer demand even after things have been shipping for a while. So it is with the “Fleetwood” Power E980 system that IBM debuted last summer using the “Cumulus” 12-core, heavy thread variant of the Power9 processor family and the Enterprise Pool CPU capacity pooling software that runs on enterprise-class Power Systems iron.

  But before we get into all of that, a reminder of what we are expecting to see from …

• Setting The Stage For The Next Decade Of Processing

  August 12, 2019 Timothy Prickett Morgan

  It is no secret that Moore’s Law is causing all kinds of grief with chip designers working in all parts of the IT stack. It was bad enough to run out of clock scaling when Dennard Scaling stopped, and the industry has done a great job in making processors more parallel and allowing for them to offload processing to various kinds of accelerators, either on the die, in the package, or in the chassis over high speed interconnects. But even this is running out of gas as processors keep pushing up against the reticle limits of lithography machines because the …

• Power Systems Keeps Growing Against A Tough Compare

  July 22, 2019 Timothy Prickett Morgan

  This time last year, Big Blue was just starting to ship Power9-based systems for the “Summit” and “Sierra” supercomputers built for the U.S. Department of Energy’s Oak Ridge National Laboratory and Lawrence Livermore National Laboratory, and that gave the Power Systems line a revenue bump through the third and fourth quarters of last year. There is no such big deal this year, although IBM has sold a baby version of these machines – if you consider the 25 petaflops “Pangea III” supercomputer small – to European oil and gas giant Total.

  That deal with Total surely helped IBM make its …

• IBM i Roadmap Promises A Long Ride, Few Bumps

  June 10, 2019 Timothy Prickett Morgan

  It would be hard to find a group of enterprise IT shops that are more conservative – meaning averse to risk – than the IBM midrange. Arguably, IBM System z mainframe shops are even more risk averse, but perhaps it is a matter more of scale than degree. In the average IBM i shop, one person – or maybe a handful of people – is keeping risk at bay, while in a mainframe shop there could be dozens or hundreds that are trying to steer the ship without rocking the boat.

  Every now and then, Big Blue publishes an IBM …
