Energy proportional data centers optimize power consumption

Posted in asset-utilization, data-center, data-center-network, dynamic-infrastructure, energy-proportional, google, low-power, power-utilization on July 7th, 2010 by FrankM – Comments Off

Google research looks to develop energy proportional data centers that throttle power based on network utilization.  The technique involves modifying the network topology and dynamically tuning network switches.  …

…   “the authors suggest several ways to build data center networks that use power in proportion to the volume of data being transmitted, rather than running at high-power during periods of both high and low utilization. ”   …

Data Center ASHRAE Prescriptive Cooling System Energy Efficiency

Posted in air-economizers, ambient-air-cooling, ashrae, cooling-system, data-center-efficiency-program, economizer, energy-efficiency, google, standards on April 13th, 2010 by FrankM – Comments Off

Google and its industry peers react to ASHRAE cooling standard for data centers. …

… “Unfortunately, the proposed ASHRAE standard is far too prescriptive. Instead of setting a required level of efficiency for the cooling system as a whole, the standard dictates which types of cooling methods must be used. For example, the standard requires data centers to use economizers — systems that use ambient air for cooling. In many cases, economizers are a great way to cool a data center (in fact, many of our companies’ data centers use them extensively), but simply requiring their use doesn’t guarantee an efficient system, and they may not be the best choice. Future cooling methods may achieve the same or better results without the use of economizers altogether. An efficiency standard should not prohibit such innovation. ” …

Data Center performance monitoring
Google uses the Power Usage Effectiveness metric to monitor the performance of its data centers. When it assess variability in its efficiency, Google takes action to remedy the defect. …

… “As we review our real-time efficiency performance we might, for example, notice that one of our data centers is not performing consistently with others of similar size and locale. So we’ll take a closer look at optimizing that facility. Are we using fans to cool spaces that don’t need to be cooled? Is the thermostat at the right set-point? Can we reduce the time the chillers need to run while keeping the machines operational? ” …

Google shares their insight and experience with efficient data centers. …

Google data center efficiency leadership

… “our data centers use considerably less energy for the servers themselves, and much less energy for cooling, than a typical data center. We achieved this milestone by significantly reducing the amount of energy needed for the data center facility overhead. Specifically, Google-designed data centers use nearly five times less energy than conventional facilities to feed and cool the computers inside. Our engineers worked hard to optimize every element in the data center, from the chip to the cooling tower. ” …
