And here we are. It’s almost November 2011, and both are about to come to pass.

The zEnterprise 196 and the Business Class version, the zEnterprise 114, mainframes come with the zEnterprise BladeCenter Extension. Initially this supported AIX on Power blades and Linux on x86 blades. This fit nicely with IBM’s model of the universe because it owns AIX and Linux is, of course, open source – ie it doesn’t belong to anybody. The Unified Resource Manager (URM) controls the operating systems and hypervisors on the mainframe and the blades. But now – the previously unthinkable – IBM promises that it will have Windows running on its HX5 Xeon-based blade servers for the zBX chassis before the end of this year.

Microsoft Windows Server 2008 R2 Datacenter Edition will run on the PS701 blade servers in the zBX enclosures. The zBX extension can have 112 PS701 blades or 28 HX5 blades.

This is clearly important for those sites that use mainframes or are ready to upgrade to mainframes and still have a big Windows-using population. It’s interesting that so many people consider Windows to be the de facto computing platform. I recently had a conversation where Windows laptops were given the metaphor of rats or beetles – they just turn up everywhere – and Linux was given the metaphor of a stealth operating system or a hidden shadow – it was everywhere, but you didn’t see it. Why stealth, well because Linux turns up behind the scenes on routers, on TiVO boxes, on supercomputers, as the precursor to Android on smartphones, making movies at Pixar and Dreamworks, in the military, governments, everywhere!

After Windows on IBM hardware, the next thing we hear is that Virginia M Rometty, a senior vice president at IBM, is going to be the company’s next CEO – starting in January. “Ginni”, aged 54 (as all the releases inform us), succeeds Samuel J Palmisano, who is 60, and will remain as chairman.

Ms Rometty graduated from Northwestern University with a degree in computer science, joined IBM in 1981 as a systems engineer. She moved through different management jobs, working with clients in a variety of industries. Her big coup was in 2002, when she played a major part in the  purchase of the very big consulting firm, PricewaterhouseCoopers Consulting. PwC staff were used to working in a different way from IBM’s and managing that culture shift was down to Ms Rometty.

In 2009, Ginni became senior vice president and group executive for sales, marketing, and strategy.

You’ll recall that Sam Palmisano took over in 2003 from Louis V Gerstner Jr, who’d joined IBM from RJR Nabisco in 1993 and helped turn round an ailing IBM. The previous incumbent had been the lacklustre John Akers.

I suppose with Siri on iPhones and the much less serious about itself Iris on Android, we’ve moved some way towards being able to talk to a computer – even if it is a smartphone. Still no sign of Scotty being beamed up, though!

During the 1970s, computing, where it existed, was very much a centralized affair. The gods of the mainframe pretty much controlled what anyone was able to do. It was like Stalinist Russia. Everything came out of the centre. You didn’t get it, unless someone at the hub of things deemed it necessary for you to have it.

Currently in the UK, we have the opposite approach in terms of our model of how things should work. Quite logically, you might think, if you live in a rural area with rolling fields full of wheat or livestock, your concerns are completely different from those of someone living in a post-industrial run-down urban area. Of course, this localism easily lends itself to the criticism of postcode lottery. Anyway, we have little islands of individuality separate from each other. Unfortunately, the reality is that political areas tend to include more than a monoculture of just rural or just urban populations. Plus you have different needs for different age groups – you can see where this idea falls down when applied to the real world, but hang on to the little islands metaphor.

Now let’s turn time back to 1989. We find the Berlin wall coming down and the whole centralized power base of the USSR and it’s Warsaw Pack allies crumbling. In the world of computing, we find the balance of opinion has moved right away from mainframes. In the early 90s, their death was confidently predicted. In its place we had millions of underpowered PCs running DOS-based operating systems. And as the 90s progressed we saw the triumph of Windows and Microsoft. We also saw that antithesis of centralization, Open Source software. Unix started life in 1969, and Linus Torvalds’ Linux arrived in 1991. Even IBM, which had developed and standardized the PC in the early 1980s, was working on the development of other platforms. 1988 gave us the AS/400 – now the IBM System i and which now runs on the POWER platform. The RS/6000, running a Unix variant called AIX, arrived in the 1990s and also now run on POWER hardware.

So, having been empowered to make their own decisions and choices of hardware and software, what have users done since then? Well, in the PC world, they go for big servers that are virtualized in order to benefit from the control that gives them. It makes back-ups and business continuity easier.

And now, here we are in 2011 and IBM announces a Business Class (basically not a top-end machine, more one for the everyman mainframe user) zEnterprise – the z114. It’s gone back to being a centralized piece of hardware because not only is it a mainframe, it’s a POWER7 box, and it has x86 blades. So that gives users a smaller footprint, less power consumption, and control of everything using the IBM zEnterprise Unified Resource Manager and the IBM zEnterprise BladeCenter Extension (zBX). The POWER7 blades mean that AS/400 and RS/6000-heritage users have a home. And the x86 blades not only run Linux x86 applications unchanged, but, by the end of the year, are expected to run Windows applications too.

The culture shock at many sites will come when the distributed applications teams (and they may have many different names) discover that all the things they’ve been planning to achieve (virtualized desktops, virtualized servers, etc) are just part of the techniques that the mainframe people take for granted. And the mainframers are going to have to understand that for many of the people in the other teams, it’s in many ways still about 1992 in terms of business recovery times etc. But when the teams do come together, the synergy is going to be very beneficial for the organization that allow it to happen.

This new mainframe, unusually, comes with a published price tag – $75,000. As part of the package you get the IBM Smart Analytics Optimizer to analyse data faster at a lower cost per transaction, and the IBM WebSphere DataPower XI50 for integrating Web-based workloads. The new hardware runs the latest version of z/OS – 1.13. You get 3.8GHz processors (the zEnterprise 196 uses  5.3GHz processors), and you can configure up to 14 of them with 10 specialty processors – zIIP, zAAP, and IFL.

The pendulum has now swung completely back. We have a single box capable of providing all the different computing needs of an organization.

Given that virtualisation is happening, IT departments have a choice: roll out a scale-out architecture using a large volume of x86 servers to run virtual machines, or deploy a scale-up architecture, comprising fewer much larger, and often more expensive, Unix and Linux server boxes over commodity Windows hardware.

IBM’s new z/196 mainframe aims to tackle datacentre complexity by pulling together different applications, or workloads, in a single system. The system comprises a mainframe and Power and x86 blades, which enables the datacentre to run mainframe, Aix and Linux applications in the same floor space.
