Power Supplies – Friend or Foe?I thought a high efficiency power supply was going to fix my problems? Maybe. And you have a choice to make. As we have written elsewhere, carbon cap-and-trade will focus on total energy consumption, and we’re looking at all corners of the data center for gross energy cutting efforts. As [Read more]

Back from vacation and some key meetings, so back on the dais. Metering is one of the least appreciated platforms in the data center. Metering is rarely integrated across the building, nor is it properly applied to critical power system. So, how ar you ever going to get a realistic PUE when your ruler is [Read more]

Now That the Power’s Lower, What Do I Do?Part Three of Three As data center professionals employ techniques to save energy in the data center, the big hammer is the outright reduction of the power the process consumes. This is very different from raising the efficiency of the systems that serve that load. The changes [Read more]

Where Did My Efficiency Go? European Voltage and the Elimination of Magnetics Part Two of ThreeIn the last post, we pointed out that system loading, when above or below a relatively narrow band, can be actually quite poor. In this post, we’re dealing with the current design fad of delinving power to the IT system [Read more]

Where Did My Efficiency Go? Critical Power System Loading & Equipment OperationsPart One of Three Many data center owners and designers accept that the reduction of power consumption as a core goal for their facility designs and operations. What is routinely missed is that the component selection, critical power (CP) system loading, the electrical system [Read more]

In this day and age, everyone wants to become greener. Motivations vary: reduction of operating costs by reducing energy consumption, reduction of carbon footprint and the impact of pending carbon taxes on high-energy users, leave the planet in good shape for our kids, PR, whatever. Square foot – square foot, data centers consume more energy [Read more]

Welcome to my new blog. Like many of my colleagues in the mission – critical facilities and operations business, my approach to this industry is collaborative, in a fair exchange or ideas. Periodically, I will post my thoughts on data center infrastructure, project development, trends and trends or new issues that I think need some [Read more]
