• Power10 Boosts NVM-Express Flash Performance

  June 5, 2023 Timothy Prickett Morgan

  We are always on the lookout for any performance tests that show the benefits of adding flash storage to Power Systems iron, and we found some recently in an NVM-Express flash drive deep drive given by Douglas Gibb’s the I/O product manager for the Power Systems line at IBM during the POWERUp 2023 conference in Denver.

  The presentation that Gibbs gave went through all of the ins and outs of flash storage on Power Systems, including those that use the NVM-Express protocol over the PCI-Express peripheral bus, which offers a direct link between the operating system and the flash storage …

• Update On Critical Security Vulnerability In PowerVM

  May 24, 2023 Timothy Prickett Morgan

  Earlier this week, we told you about a very serious security vulnerability in the PowerVM hypervisor when running on Power9 and Power10 systems. IBM found the vulnerability itself and immediately set about to patch the vulnerability, which it revealed on May 17 along with patches to firmware in systems that are managed by the Hardware Management Console, or HMC.

  What was not necessarily apparent was that there are plenty of Power Systems customers who do not have HMCs managing their systems and the logical partitions upon them, and this is particularly true of the IBM i installed base, which …

• Critical Security Vulnerability In PowerVM Hypervisor

  May 22, 2023 Timothy Prickett Morgan

  IBM’s Product Security Incident Response Team (PSIRT) put out a notice on Wednesday, May 17, to inform the Power Systems installed base that there is a very serious security vulnerability in the PowerVM hypervisor. You can see the PSIRT notice at this link and the Security Bulletin: This Power System firmware update is being released to address CVE 2023-30438 at this link. This has a CVSS base score of 9.3, which means it is critical.

  We very rarely see any security vulnerabilities being reported for the PowerVM hypervisor or for the IBM i operating system itself, for that matter, …

• IBM i PTF Guide, Volume 25, Number 21

  May 22, 2023 Doug Bidwell

  As we report elsewhere in this week’s edition of The Four Hundred, there is a critical security vulnerability in the PowerVM hypervisor when it is running on Power9 and Power10 systems.

  This HIPER/Pervasive patch is described as fixing this: An internally discovered vulnerability in PowerVM on Power9 and Power10 systems could allow an attacker with privileged user access to a logical partition to perform an undetected violation of the isolation between logical partitions which could lead to data leakage or the execution of arbitrary code in other logical partitions on the same physical server.

  The Common Vulnerability and Exposure …

• Inside IBM’s Efforts To Modernize The ISV Army

  May 15, 2023 Alex Woodie

  “You go to war with the army you have, not the army you might want or wish to have at a later time.” IBM executives must feel a bit like the eminently quotable Don Rumsfeld, former Secretary of the Department of Defense, as they marshal their assets in the battle for application supremacy. While some of Big Blue’s partners have honed their IBM i applications into modern weapons, others are fielding old equipment more suitable for a previous war.

  It’s no state secret that Big Blue has a legacy problem on its hands in the IBM i world. When the …

• The Inevitable Power9 Hardware Withdrawals Begin

  May 15, 2023 Timothy Prickett Morgan

  The high end Power10 machine, the Power E1080, has been out since September 2021 and the rest of the Power10 line was announced in July 2022, so the writing was on the wall for any Power9-based machines the minute that happened.

  The ability for IBM to get, much less sell, Power9 chips even if it wanted to is also somewhat dubious, too. In October 2014, IBM sold off its Microelectronics division to Globalfoundries, itself a spinout of AMD’s foundry business five years earlier mashed up with Chartered Semiconductor and backed by the government of Abu Dhabi. Here’s the complication: …

• IBM Updates Performance Guide For Latest Power10 Iron

  May 1, 2023 Timothy Prickett Morgan

  No matter what system you are talking about, no matter what kind of applications you are running, there are always ways to squeeze more performance out of the system. The IBM i platform running atop Power10 and earlier processors is no exception, and to that end, for several years now Big Blue has provided some guidance on pushing performance with each new CPU family and as new features are added to the OS/400 and IBM i software stack.

  The latest such update, according to Steve Will, chief architect of the IBM i platform, has just been published, and you can …

• An Update On Power From POWERUp 2023

  April 26, 2023 Timothy Prickett Morgan

  After so many years of not normal, it is comforting to do something to feel normal, like travel to what used to be the COMMON spring user conference and what is now called POWERUp, and in particular POWERUp 2023. (I am only using the official capitalization there because Jenny will change it during edit if I don’t.) I don’t want to leave the hill I live on, especially after so many years of traveling many times a month, but I must say that I enjoyed myself and had my share of boisterous conversations, beer, and food.

  And work, of course. …

• Big Blue Refreshes The Technology for IBM i 7.4 And 7.5

  April 12, 2023 Alex Woodie

  As expected, IBM yesterday unveiled its Technology Refreshes (TRs) for IBM i, including version 7.5 TR2 and 7.4 TR8. These are relatively minor releases that bring incremental improvements to core areas of the platform, including IBM i Navigator, IWS, PowerHA, and RPG, among others. There’s nothing groundbreaking here, but the enhancements are undoubtedly just what many users need.

  We’re going to dive into each of the enhancements and do full coverage of them in the coming weeks here at IT Jungle. For today, we’re going to provide a broad overview of the new stuff that IBM just announced this …

• Tweaks To The Power Software Stack, And Red Hat Gets Easier

  April 12, 2023 Timothy Prickett Morgan

  Whenever there are Technology Refreshes for the IBM i operating system, its database, and the related systems and development tools for IBM i, you can bet Elon Musk’s last dollar that there will also be nips and tucks, and sometimes more significant changes, to the adjunct software that runs on Power Systems iron. Such as the PowerVM server virtualization hypervisor, the PowerVC implementation of the OpenStack cloud controller, the PowerSC security tools, and other things.

  And indeed, as part of the April 11 announcements, IBM has tweaked this Power Systems stuff. This is not one of the big ones, as …
