  • A Focus on High-End Storage the CLIPPER GROUP
    When Infrastructure Really Matters - A Focus on High-End Storage THE CLIPPER GROUP TM SM Navigator Navigating Information Technology Horizons Published Since 1993 Report #TCG2012021 October 2, 2012 When Infrastructure Really Matters — A Focus on High-End Storage Analysts: David Reine and Jim Baker Management Summary Except for those who rely solely on public transportation or walking, most of us have a vehicle or two (or more) for our (family’s) personal use. We all have our strategies about the vehicles that we drive, whether economy, capacity, style, performance, etc. For the authors, and probably for most vehicle own- ers, a primary requirement for our vehicle is that it be reliable. Having an unreliable vehicle has known and unknown consequences. First, there is the inconvenience of it failing in some way, especially when it needs immediate servicing. The known consequences are those that can be predicted in advance, like not being able to get to work or pick up the kids on time. Time disruptions are a direct consequence of some- thing that is unreliable. Unfortunately, there are even more consequences, which tend to be more indirect yet possibly more consequential. If you were on your way to meet with a client about a critical deal and you are delayed or can’t get there, you and your business may lose that deal. Each vehicle owner has a strategy (or “Plan B”) for dealing with a suddenly ailing vehicle. Some may not drive a vehicle more than a couple of years old, because unreliability increases with age. Others may have another vehicle on which to rely in an emergency, like one belonging to a spouse or child, but relying on these also has downstream consequences.
