• If It Ain’t Broke, Don’t Fix It

  March 13, 2024 Alex Woodie

  The information technology industry has a “newness” bias. It always has, and probably always will. But when it comes to the systems for processing business transactions, decision makers need to think carefully about what they’re doing, as ditching “legacy technology” for a shiny new one doesn’t always deliver the promised upgrade.

  The cloud is currently the hot new thing in IT. Even though it’s not necessarily “new,” and not necessarily “a technology” (it is a collection of technologies and a platform and a business model…), business owners are under tremendous pressure to “get to the cloud” by whatever means necessary. …

• What IBM i Turning 35 Means to Me

  June 21, 2023 Alex Woodie

  I started my first AS/400 writing job in the summer of 1999. I already had two part-time writing jobs at the time, for an insurance magazine and as a stringer for a local newspaper, but I wanted a full-time gig, so I did what every job seeker did back in those days: I answered a want ad in the newspaper, of course. I had no idea it would turn into a 24-year career (and counting).

  I still remember the job interview I had with Jenny Thomas, who was then known as Jenny Delroy and who was the editor of AS/400 …

• AIX: The Last Standing Commercial Unix

  February 13, 2023 Timothy Prickett Morgan

  Nearly six decades ago, a bunch of researchers at AT&T Bell Labs, MIT, and General Electric started work on a new multi-user operating system for General Electric mainframes called Multiplexed Information and Computing Service, or MULTICS. After four years of work, the project was mothballed, but was reborning when Ken Thompson, a researcher at Bell Labs, created a single-user operating system based on the ideas behind MULTICS to run on a PDP-7 that Ma Bell had laying around.

  And thus UNICS – and what would eventually become Unix and the whole open systems revolution – was born. With Unix came …

• Readiness Assessment Accelerates Moving IBM i Workloads To The Cloud

  November 7, 2022 Timothy Prickett Morgan

  There are on the order of 120,000 unique IBM i customers in the world, and the one thing they all have in common is that they are absolutely – each and every one of them – unique. There are no two customers alike because they have lots of homegrown code, or a mix of their own code and that of an ISV, or maybe they have a heavily customized stack from an ISV.

  We defy you to find one customer – even one – that is running any software from a third party as it is, out of the shrink …

• The Scoop On The Full Subscription Power S1014 With IBM i

  September 12, 2022 Timothy Prickett Morgan

  Even before the Power10 entry and midrange servers were announced by Big Blue on July 12, we did a thought experiment at the end of June about a rumored hardware-software-maintenance bundle on the single-socket Power S1014 server aimed at IBM i customers with a single monthly subscription price. And for fun, that thought experiment compared the monthly cost of a high-end iPhone smartphone with cell service and a data plan – somewhere between $75 and $80 – to what we expected such a full subscription-based, on premises Power S1014 would cost. We figured it would be around $50 per IBM …

• Building A More Perfect IBM i Cloud On Power10 Iron

  January 24, 2022 Timothy Prickett Morgan

  As we get closer to the launch of the entry and midrange Power10 machines, we can’t help but think about the innovative uses that these machines might be put to. We think, for instance, that these machines could be the foundation of a new generation – and a new kind – of IBM i cloud based on a mix of entry one-socket Power S1021 and two-socket Power S1022, and Power S1024 machines augmented in a very special way with four-socket Power E1050s.

  To one way of thinking, the easiest way to build a big cloud capable of supporting thousands of …

• What IBM i Shops Want From Cloud, And How To Do It Right

  September 27, 2021 Timothy Prickett Morgan

  It is no secret to readers of The Four Hundred that we are big proponents of so-called cloud computing, which doesn’t just include access to slices of servers but also storage to keep their data and networking to link them to the world and, if multiple slices share work, to link them to storage and to each other.

  We never liked the term “cloud,” because it connotes a fuzzy kind of infrastructure when quite the opposite is true. We still don’t like calling it cloud computing, but language is created by consensus, not by fiat, so sometimes we have to …

• 2021 Predictions for IBM i: Part Two

  January 20, 2021 Alex Woodie

  The response from the first batch of IBM i prediction we ran last week was superb. Here’s hoping that the community finds the second batch of predictions equally as worthwhile.

  Chris Wey, the president of the Power Business Unit at Rocket Software, wonders if crystal balls have any power left following the events of last year. “After an unpredictable 2020, the very notion of predictions is called into question,” Wey says. “Still, as an optimist, I believe we will see some incredibly positive outcomes of the past year’s turmoil in the coming year in our space.

  “First, Power systems …

• How Much Does NVM-Express Flash Really Boost IBM i Performance?

  November 9, 2020 Timothy Prickett Morgan

  With the NVM-Express protocol, a storage overlay for the PCI-Express peripheral bus that allows flash to be addressed in a parallel fashion as flash in its own right and not as emulated disk storage using a SATA or SCSI protocol, the idea is to get those vintage storage drivers out of the way and let the operating system kernel speak directly to the flash. This is done so the impressive – and seemingly always growing – I/O bandwidth of flash can actually be brought to bear to speed up applications.

  Flash in general, and NVM-Express flash in particular, has been …

• How IBM Stacks Power Cloud Up Against AWS And Azure

  August 3, 2020 Timothy Prickett Morgan

  We have our own habits when it comes to thinking about bang for the buck, and it is refreshing sometimes to just think about how other companies think about it.

  As part of the July 14 announcements now almost three weeks ago, IBM not only rolled out new entry Power9 machines with higher I/O bandwidth as well as utility style pricing for on-premises gear to lower capital expenditures. IBM also did a direct comparison of the Power Systems Virtual Server running on the IBM Cloud for a memory-heavy instance and then compared that to fat memory slices running on Amazon …
