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.
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.
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.
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.
For our readers in the New York area who are interested in the subject of green data center design the Green Grid is hosting an exclusive high level industry discussion in New York, NY on October 2nd, 2009. The event will feature a prominent industry discussion and forum on green data center design.
The Green Grid is a consortium of many of the world’s leading tech and telecom companies with the goal of promoting efficient green data center designs and technologies that use less energy and water as well as recycle the computing and support equipment used by data centers.
The first wave of green IT solutions failed to make sustainability benefits tangible according to a new study conducted on the sector by the independent research firm Verdantix. However, innovative IT sustainability solutions just released into the market or on the horizon for 2010 – will quickly demonstrate the tech sector’s role in supporting corporate sustainability strategies.
Can Off-peak Air Conditioning (OPAC) technology, improve the green energy profile of data centers? One of the major energy consumption categories of data centers is their need to keep all of their rows of rack mounted servers operating within their critical temperature parameters. Many various techniques are increasingly being adopted by data centers around the world in order to lower their overall cooling needs. An additional technology exists that I believe can help data centers improve their energy usage profiles by shifting energy demand to off-peak hours and in so doing significantly lower their energy consumption during critical periods of peak demand. Off-peak Air Conditioning (OPAC) technology is a way for data centers to improve their peak energy demand profile.
