• Dell And Big Blue Call It Quits On Storage Driver Support For IBM i

  December 9, 2024 Timothy Prickett Morgan

  It looks like IBM and sometime rival Dell Technologies are having a tiff over the licensing of technology that allows disk arrays descended from the venerable Symmetrix arrays created by EMC more than three decades ago to link to descendants of the AS/400 platform and OS/400 operating systems created three and a half decades ago.

  The fallout from what we presume is that a technology licensing fee agreement between Dell and IBM is similar, we think, to the one between IBM and the company that owns Information Builders. In October 2023, out of the blue, IBM announced that it was …

• Surprise! It’s 2024 Fall TR Time for IBM i

  October 9, 2024 Alex Woodie

  IBM announced the Technology Refreshes (TRs) for IBM i version 7.5 and 7.4 yesterday, bringing a host of new capabilities to the proprietary operating system. As expected, the surprise update covers a range of IBM i facilities, including Db2, Navigator, ACS, PowerHA, and the development tools.

  Navigator gets several more enhancements with the new TRs, including: a new dashboard with software licensing information; Web-based administration of network facilities; support for monitoring of Java 11 and Java 17 jobs; enhancements to the Performance Data Investigator (PDI); and new options for working with audit journals, among other capabilities.

  IBM also includes the …

• DR Testing As A Service: One More Thing That You Don’t Have To Do

  September 25, 2023 David Fahrenkrug

  If not having a disaster recovery plan for your IBM i system is scary to think about – and clearly a lot of IBM i shops are not thinking about it beyond restoring from tape or virtual tape library because if they did, they would get together a disaster recovery plan – then maybe between the fifth and tenth most scary things in the datacenter today is actually making sure that the disaster recovery software works and the plan for recovery in the event of something going haywire actually works.

  High availability clustering and disaster recovery software is, by necessity, …

• IBM Tweaks Some Power Systems Prices Down, Others Up

  March 27, 2023 Timothy Prickett Morgan

  Back in September and November of last year, with inflation running a bit crazy, IBM raised prices on selected Power Systems hardware and software with the price changes taking effect on January 1 this year. We went into the details back then, of course, but we are being proactive in looking for any price hikes that might come out of Big Blue relating to its Power Systems machines, systems software, and related storage and networking. And, as it turns out, there have been some more pricing actions that you need to be aware of.

  As we have pointed out …

• Some Power Systems Hardware Tweaks

  October 17, 2022 Timothy Prickett Morgan

  Whenever there is a software update on the Power Systems line, IBM usually has a few hardware announcements to toss into the mix. And last week was no exception, although there were not any new systems announced. Just tweaks to existing ones.

  In announcement letter 122-084, we see that IBM is reselling Nvidia’s two port, 100 Gb/sec ConnectX-6 DX network interface card on the Power10 lineup. This is a very popular NIC out there in Server Land, and in fact, it has been in short enough supply in the past year and change to actually have an impact on …

• Give Me A Fulcrum And A Lever Long Enough, And I Can Move Your Data

  July 13, 2022 Brad Jensen

  An old adage about the power of mechanics and physics illustrates perfectly how we feel about virtual tape libraries, and not just the ones made by us, but about other VTL wares out there in the field: Give me a fulcrum and a lever long enough and I can move the world.

  We know that there are other good VTL tools out there, and it is good because the competition keeps us all honest. The important thing is that using VTL brings IT organizations out of the Stone Age of managing data archives and backups.

  First off, if you are …

• Getting A Firm Handle On Power Systems And Storage Firmware

  June 15, 2022 Richard Warren

  Back in the old days of the AS/400 and the iSeries, most customers had a single box or maybe two, one for production applications and databases and one for development of high availability. And everything that box needed was inside of itself.

  And at most, you applied two kinds of PTFs – those for the operating system and those for the microcode – to the machine, and you did that maybe once or twice a year and every once in a while you might add some group PTFs to update security or other important features.

  But the world has changed …

• IBM Power: How Strong Is Your Backup Game?

  June 8, 2022 Jason Hardy

  Your business runs on IT and chances are if your systems are down, your business is down. Have you contemplated the most common reasons for data loss and whether your strategy can protect you in the event of natural disaster, hardware failure, fire, ransomware, human error or theft? Depending on the reason for your outage, you may experience data loss and need to leverage your backups to recover. Are you confident in your backup and recovery strategy?

  One of the simplest tests you can do to assess your backup strategy is to see how you stack up against the 3-2-1 …

• Guru: IBM i Experience Sharing Case 4 – Investigating Time-Sensitive Transaction Issues

  June 6, 2022 Satid Singkorapoom

  Among the central processing hardware resources in a computer system – CPU, GPU, memory, disk, PCI-Express I/O bus – disk has always been the slowest component. Even the latest flash disk or NVM-Express flash drive or card is slowest, but not by much. Back in the days of hard disk, disk I/O was the most popular cause of performance problems. From experience, I always looked at it first in my investigation.

  The modern SAN flash disk can still be the performance bottleneck when it is not deployed properly, as I shared in Guru: IBM i Experience Sharing, Case 3 – …

• Guru: IBM i Experience Sharing, Case 3 – When Performance Issues Come From Without

  April 4, 2022 Satid Singkorapoom

  When I started my IT career 35 years ago, it was in the “centralized” universe that originated from the mainframe model. All core application codes ran in one — and only one — big iron that all users accessed with “dumb” terminals devoid of any GUI. Problem solving in AS/400 systems was frequently straightforward and not time consuming because most cases were anything but elusive.

  But the contemporary IT infrastructure universe has evolved into a big onion, with layers that we must peel while troubleshooting. I often find myself having to address a problem in multiple layers, and it no …
