Operating Systems

The power of High Performance Computing (HPC) is well-established, whether it’s being applied to weather forecasting and climate analysis, genome modeling and analyses of neuron function, or material modeling for new generations of semiconductors. But when we think of HPC, we think of supercomputers, colleges, universities and research institutes. IBM has always been a major player in this space, which is why the recognition of Sequoia, the IBM Blue Gene/Q system installed at the Lawrence Livermore National Laboratory in Livermore, CA, for the Department of Energy, as the number one ranked supercomputer in the world came as no surprise.

Of more immediate interest to enterprises, however, is the fact that IBM, with the finalization of its 2012 acquisition of Platform Computing, has moved aggressively to create an HPC solution capable of scaling to the needs and budgets of enterprises. Earlier in 2012, Helene Armitage, general manager of IBM Systems Software, said that: “The acquisition of Platform Computing will help accelerate IBM's growth in smarter computing, a key initiative in IBM's Smarter Planet strategy, by extending the reach of our HPC offerings into the high growth segment of technical computing ... . Our intent is to enable clients to uncover insights from growing volumes of data so they can take actions that optimize business results.”…

I’m not a fan of clouds. I bristle when I hear the term used. It has become a fetish in business circles where non-technical managers speak of clouds to mask their lack of knowledge of the black arts of IT, and it’s a fixture in vendor marketing brochures, where it satisfies the dual criteria of marketecture: It sounds technical but means whatever a vendor says it means…

Many large organizations are implementing private clouds to enable on-demand network access to a shared pool of computing resources they can easily and quickly configure and provide. Although the main focus of cloud computing has been on the distributed infrastructure, organizations have learned that the zEnterprise also works well for implementing private cloud using Platform as a Service (PaaS)…

Ask people about their IT strategy and you often get a long answer. I’ve looked around a bit, and the definition that appeals to me most is one I found on the CioIndex Website at www.cioindex.com: IT strategy is an iterative process to align IT capability with business requirements. The author adds a few extras to clarify this succinct definition:…

There’s more than one way to save on CPU consumption. Moving workloads to System z Integrated Information Processor (zIIP) engines has been a popular option. However, many organizations are also exploring using IBM’s DB2 Analytics Accelerator (IDAA) as an option for lowering costs and optimizing the performance of the mainframe. IDAA is a specialty machine that offers faster and more predictable response times for long-running, unpredictable queries. It does this by reducing database tuning efforts and off-loading query workloads. If you’re looking into moving workloads to IDAA, here are some important factors to consider…

As companies continue to rely on the cloud to deliver their more business-critical systems, they must consider how much they can trust this new paradigm. For a cloud solution to be robust enough to host the most important systems, it must be built on top of a virtualization stack that can deliver the necessary service levels…

IBM announced new servers using the newest POWER7+ chip in October 2012. The plus (+) designation is an approach IBM has used before; most recently with the POWER6+, and before that with POWER5+, to signify chip enhancements short of a full chip revision. POWER7+ provides some substantial improvements, but those expecting POWER8, which IBM has been telegraphing for months, will be disappointed. Still, there’s much in POWER7+ to help Power shops improve overall system performance…

I recently presented at a large conference, and one of the slides I used showed the journey of a transaction through the IT infrastructure. Using it, I explain::(Windows, UNIX and Linux), many different network and storage devices, middleware all over the place and one or more mainframes. Companies found themselves using many different tools to monitor the health of transactions that touched all these various components, on many different platforms, monitoring and managing tens of thousands of transactions.Managing IT From a Business Perspective…
