Is the Rising Data Center Energy Crisis Over?

Is the Rising Data Center Energy Crisis Over?

This post on the subject of growing energy usage by data centers examining a recent report on how the rate of increase in the energy usage for data centers has been quite a bit lower than was predicted. It goes on to argue that the report may not be capturing the whole picture and that important areas of energy usage by data centers have not been factored into the report.

Watts Up: Does Virtualization Really Save Energy?

Watts Up: Does Virtualization Really Save Energy?

Lays out the case for how using virtualization can save very significant amounts of energy, especially in large data centers. Breaks down resource requirements in terms of RAM, storage and ultimately cooling for a stand alone server configuration and a comparable virtualization configuration and builds a case for why and how virtualization can significantly reduce energy usage requirements for data centers.

Is it Time for a Bio-Mass Powered Data Center?

Is it Time for a Bio-Mass Powered Data Center?

This post explores the concept of an end-to-end ‘green’ power, water, and community eco-system based around mega-watt scale power and cooling requirements in a real world environment of limited financial resources and stringent system availability requirements. It suggests that huge power hungry data centers should consider incorporating on-site biomass electricity generation as an integral part of their operations systems.

Top 10 Things Data Centers Forget About PUE

Top 10 Things Data Centers Forget About PUE

In the race for the title of the world’s greenest data center a lot of perhaps overly optimistic PUE claims have been made. Power usage effectiveness (PUE) is a measure of how efficiently a computer data center uses its power. While it is a step in the right direction it still fails to capture the complete picture of the data center’s energy and resource efficiency. It goes on to point out ten areas that are not being captured; some of which have significant implications.

Facebook Open Compute and the PUE Trifecta

Facebook Open Compute and the PUE Trifecta

In this post Julius discusses some of the innovations that are cropping up in forward thinking data center design ranging from the adoption of Yahoo’s chicken coop architecture that is suited for utilizing ambient air cooling; new server designs optimized for hot aisle/cold aisle architecture; and innovative approaches to power supply. While most operators do not have the deep pockets and resources of players like Facebook, Google, Yahoo or Amazon — all mentioned in this post — the kinds of forward thinking innovations being pioneered by these companies are bound to have a wider impact.

So You’re Building a “Green” Data Center”

So You’re Building a “Green” Data Center”

Building a green data center is a challenging undertaking; it is also one that is poorly understood and that can fail in many ways. This post goes into some of the deeper level goals that need to be kept in focus if the project is going to be a success.
