IBM’s zEnterprise Really Stretches Its Boundaries — New Windows Are Opened

  1. 1. IBM’s zEnterprise Really Stretches Its Boundaries - New Windows Are OpenedTHE CLIPPER GROUPNavigator TM SM SM Navigating Information Technology HorizonsPublished Since 1993 Report #TCG2011034LI October 12, 2011 IBM’s zEnterprise Really Stretches Its Boundaries — New Windows Are Opened Analyst: Stephen D. Bartlett Management Summary You can’t read the news on technology without engaging in speculation on what’s about to be announced, the significance of what it will mean, who will be affected, and how the marketplace will change. Since the technology is not just institutional but very personal for those of us in IT, we must try to sort out the meaningful from the overlapping waves of bravado and noise. IBM mainframe sales reps and distributors don’t enjoy the pleasures and satisfaction of the whole world’s anticipation, speculation, or even the organized illicit intelligence gathering, which seems to be common in Apple’s i-world these days. There was a time, beyond the memories of most of the IT community, when they did, but the world has changed and new technologies have driven the focus to a broader audience that is less sophisticated in many respects. As a consequence, the “fun stuff” has shifted a good deal from what’s the biggest and fastest, toward what is the latest, and usually smaller, innovation – the new gotta’ have. Computing, if you will, now is more personal and portable. Does anyone care what all this stuff is connected to and what holds it together anymore? Not so much, apparently. If a tree falls in the forest and there is no one there to hear it, does it make a sound? Philosophers may argue this question. One might pose an analogous question to IBM’s mainframe marketers and sales people; there is anecdotal evidence that the announcements made in the System z family since July of 2010 (namely the zEnterprise family of hardware and software products) did not reach as many dis- cerning ears as they hoped or, possibly, they were dismissed as not being relevant. I categorically dismiss the latter argument as false, which I will elaborate on later, but I do believe that IBM now needs to find opportunities to increase their bandwidth a bit and maintain the cadence that they have established. I can suggest at least two reasons why the messaging seems to have fallen short of its goals. The first is that the expansion of the hybridization of the mainframe is dramatic and innovative – a significant branch in the evolution marked by new DNA, if you will, which was completely unexpected and overwhelming. This brings us to the second reason: there seemed to be too much to behold and comprehend. For sure, there were many new elements, perhaps outside the domain of the mainframe’s typical audience, which I will review in more detail below. No doubt, some new thinking is required. That is a good thing. Progress requires that we consider new ways to address our problems. In this context, how does IT continue to support the ever-changing needs of the businesses that they support in a manner that is economically sound, non-disruptive, and open to innovation?
