IBM has made good on its promise to deliver Windows integration with the IBM mainframe via the zEnterprise System.
When IBM introduced the zEnterprise in July 2010, the company also announced plans to deliver additional general-purpose blades for the IBM zEnterprise BladeCenter Extension including IBM System x-based blades running Linux in 2011. IBM also suggested it would support Windows, and in April 2011 it confirmed its plans to deliver Windows support on z/Enterprise.

High obsolescence is a hallmark of information technology. By industry standards, 18 months, at best, is the longevity of a product or technology. But the IT space’s longest survivor, one that is there from the beginning, is the most unlikeliest of them all, the mainframe.
Its epitaph was written long ago. Universities rusticated mainframe from their curriculum decades back, thinking that skinny personal computers will drive out the bulky box that needs almost a whole room and all the paraphernalia, not to speak of a dedicated team of eternally confounded operators, to run it. But now, the storied PCs are on their way out, but the ‘big iron’ is firmly stay put, though a lot slimmer and trimmer.

The Arcati Mainframe Yearbook has been the de facto reference work for IT professionals working with z/OS (and its forerunner) systems since 2005. It includes an annual user survey, an up-to-date directory of vendors and consultants, a media guide, a strategy section with papers on mainframe trends and directions, a glossary of terminology, and a technical specification section. Each year, the Yearbook is downloaded by around 15,000 mainframe professionals. The current issue is still available at www.arcati.com/newyearbook11.

Mainframes are so amazingly powerful and versatile, wouldn’t you like to have one in your pocket? Maybe that’s not possible (yet), but there have been many attempts over the years to shrink down the mainframe to a more manageable size.
I’m not talking about some sci fi shrink ray wielded by some fearsome purple-coloured alien, I’m talking about the use of emulation software to make one lot of hardware successfully interpret instructions designed to be used on completely different hardware – and vice versa. The mainframe programs think they are running on a mainframe and continue quite happily – totally unaware of the work being performed by the emulation software.

New workloads account for almost one-third of MIPS growth, and mainframers are as optimistic as ever about the future of Big Iron.
The mainframe has never been more essential. That’s the not-so-surprising upshot of BMC Software Corp.’s sixth annual Worldwide Mainframe Survey, which — like previous years — suggests Big Iron is doing just fine, thank you.
Big mainframe shops are big MIPS consumers. MIPS capacity continues to expand: more than two-thirds of respondents (67 percent) said their transaction volumes for existing applications are growing; almost as many (65 percent) cited business growth as an important engine for MIPS expansion. Almost one-third (31 percent) said new workloads are driving MIPS growth.

For many organizations, we’re beginning to a see a model of how IT customer support can be organized – and the model is coming from management who are completely platform-agnostic. To them, IT is IT – it doesn’t matter whether something runs on a mainframe or a distributed platform. And this new way of working brings with it new challenges.
