The Deal On Power9 Memory For Entry Servers

March 5, 2018 Timothy Prickett Morgan

There are a lot of changes that come with any new Power Systems platform. But perhaps the biggest change – and one that will in some ways make the Power9 platform more competitive with X86 and ARM servers and in others less competitive – is the way IBM is shifting from buffered DDR3 and DDR4 main memory used in Power8 iron to plain vanilla registered DDR4 memory that is commonly used in all servers these days.

Buffered memory had its heyday on high-end NUMA systems, and was necessary to try to balance the needs of memory bandwidth against ever-increasing compute …

Five Strategies For Surviving A Software Audit

March 5, 2018 Alex Woodie

Dealing with a software licensing audit can be a scary thing, particularly for smaller outfits with limited resources. Martin Thompson of the Campaign for Clear Licensing recently clued IT Jungle into some of the audit strategies that big software companies are employing, and how software customers can be prepared.

Oracle, IBM, Microsoft, and SAP are widely respected for the quality of their software and the responsiveness of their technical support. But they are also feared by customers due to the legal power they hold, the restrictive licensing terms in contracts, and how they use software audits to …

In my previous tip, Sorting In Teraspace, I looked at how the qsort API can be used to sequence data in ways that SortA can’t begin to approach. Now that the data is sorted, one of the things I may want to do with it is to search it. In this tip I will look at how that can be achieved using the bsearch API. The approach I will be discussing allows for partial key searches and handling the fact that such a search may result in multiple hits.

As you will see when we work through the code, …

Most executive management does not recognize the importance of IT. They don’t understand it and, therefore, don’t see the potential business advantages that come with restructuring a system that was put in place 10, 20, or even 30 years ago. So, how important is it to influence the perception of IT within organizations?

And how do you get more business managers thinking strategically about IT? One of the keys is to demonstrate how IT is the engine for growth and not a money pit with high risk and little return on investment. There are challenges to overcome, for sure. Don’t …

Cognitive Systems Hardware Business Gets A Boost

March 5, 2018 Timothy Prickett Morgan

As 2017 came to an end, X86 server shipments and revenues surged, and IBM’s System z14 mainframes came to market and Big Blue got a much-needed injection of revenues and profits in its Cognitive Systems hardware business.

While IBM did start shipping some initial Power9 iron as the year came to an end, shipments are not going to start in earnest until March, when the “ZZ” entry Power Systems machines announced in February start shipping. In the quarter, and more or less consistent with what IBM said recently in its own financial reports, IDC believes that Big Blue had $2.69 …
