• IBM Patches Samba Vulnerabilities In IBM i

  April 16, 2018 Alex Woodie

  Big Blue has issued two patches for serious flaws in IBM i’s implementation of Samba, flaws that could result in an attacker launching a denial of service attack or changing user’s passwords. The company patched IBM i 7.2 and 7.3, as support for IBM i 7.1 wanes.

  On April 3, IBM published a security bulletin informing users of the existence of two flaws in IBM i, as well as the existence of two program temporary fixes (PTFs) to patch the problems. Both of the flaws involve Samba, a free and open source implementation of the SMB/CIFS protocol to provide interoperability …

• Counting The Cost Of IBM i On Power9 Entry Systems

  April 9, 2018 Timothy Prickett Morgan

  Every time there is a Moore’s Law advance in processing, whether companies charge by the core or by the socket, there is price cut – in theory at least – for systems software. This is true if the chip maker decides to goose the performance of the cores or add more cores to a socket, or both at the same time.

  In the past several generations of Power processors used in the Power Systems line, IBM has done both. Because the systems software is based on cores, however, the move from two to four to eight to 12 cores per …

• Insurer Chooses IBM i Database Re-Engineering Over Migration

  March 26, 2018 Dan Burger

  How do you want your database designed for the future and what problems have you created in the past that need to be fixed before you can think about the future? Old databases, originally designed for a business environment that has changed and continues to change, are not compatible. You may not be feeling any pain today and you may have no plans to change your business/IT alignment in the future, but much of the technology-driven business world is changing, which at some point will leave you alone on an island with a boat but no motor and no paddle. …

• 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 …

• At Long Last, IBM i Finally Gets Power9

  February 14, 2018 Timothy Prickett Morgan

  The most important part of the Power9 rollout for the vast majority of IBM i customers has finally happened: Big Blue has lifted the veil on the Power9-based “ZZ” systems that we have been hearing about for a few months now and that are being delivered in the Power S914, Power S922, and Power S924 servers.

  These are three of the six machines based on the ZZ design, and they are the only ones that can IBM i without any restrictions. Two other machines, which are called the Power H922 and Power H924, were created explicitly to run SAP’s HANA …

• LUG Talks About IBM i Priorities

  January 29, 2018 Alex Woodie

  The Large User Group (LUG) held its first meeting of the year last week at the IBM lab in Rochester, Minnesota. While LUG members use the IBM i platform differently than your average mid-sized company, their experiences, concerns, and vision for the future of the platform are relevant to the community as a whole. We caught up with two LUG members last week to get the low down on the i tech.

  The LUG is a private organization that keeps the identities of its members confidential. Because the overall IBM i ecosystem is relatively small, the LUG requested that IT …

• LightEdge Shops A “True Cloud” To IBM i Users

  January 29, 2018 Dan Burger

  IBM i-based cloud computing is not your average everyday IBM i environment. And it’s different from managed services that are sometimes called hosted services. True cloud – a term that’s being used to describe virtualized computing, storage, and networking available with utility-style flexible pricing – is still a rare sight with IBM i. But Roger Mellman knows where you can find one. He built it for LightEdge Solutions, a services provider with an edge on the typical managed service provider.

  IBM first approached LightEdge five years ago about building an IBM i-based cloud, Mellman, the director of enterprise …

• IBM Winds Down Yet More Older Power Systems Features

  January 29, 2018 Timothy Prickett Morgan

  It is amazing to me that IBM stops selling specific Power Systems and features in such a gradual and what looks like a haphazard fashion. It seems to take forever to kill off older product lines. It may be more a function of what supplies Big Blue has in the barn than with some kind of orderly, sensible withdrawal from marketing of prior generations of gear.

  The upshot is that it is very hard to figure out what IBM is and is not selling, and when it will stop selling particular features. And because IBM does not usually provide the …

• Update On The Spectre And Meltdown Patches For Power

  January 15, 2018 Timothy Prickett Morgan

  When it comes to the Spectre and Meltdown speculative execution security vulnerabilities that hit as the new year was getting going, the important word to ponder is “mitigated.” Everyone is talking about mitigating the issue, but no one is using the word “fixed.” As we discussed last week, one of the two types of Spectre vulnerabilities – the Variant 2 known as branch target injection – is particularly tricky to hack and to fix, so IT vendors are choosing their words very carefully.

  The odds were that unintended consequences for such a low-level fix will occur, so you can …
