Five years ago, large organizations were just starting to become aware of the green agenda. Recycling and cutting their carbon footprint could improve their image, they realized. They gave the responsibility to their corporate social responsibility (CSR) officers and prepared to invest.
You want to see a data center professional get hot under the collar? Suggest that maybe his data center cooling isn’t all that great. Data center professionals view data center cooling as both a point of pride and frustration – they are each very aware that it’s a constant struggle and even the slightest tweak can make a huge difference – both in saving the planet and saving money for the organization.
Data centers, the key backbone of the cloud, are growing larger and more energy intensive, prompting the Department of Energy (DOE) to launch a new initiative on Tuesday aimed at improving their energy efficiency.
According to DOE statistics, data center electricity use doubled between 2001 to 2006, from 30 to 60 billion kilowatt-hours of electricity, and stood at about 100 billion kilowatt-hours of electricity as of 2013. This amounts to about 2% of all U.S. electricity use and climbing.
Used to build everything from a planetarium in post-WWI Germany to mobile yoga studios at outdoor festivals today, the geodesic dome has proven to be a lasting concept for highly stable structures of any size. Structural stability is a valued goal in data center design, but the idea of building a data center shell using a spherical skeleton that consist of great circles intersecting to form a series of triangles – the most stable shape we know of – is novel.
Cloud computing, new applications and a lot more user connectivity are all driving forces around the data center evolution. In fact, the data center has become the home of all modern technologies. Businesses are now building their entire organizational model around the capabilities of IT. Through it all, pressure continues to mount on data center operators to run high-efficiency environments capable of good power control.
Server densities are steadily increasing for HPC applications in legacy, government and institutional data centers. As densities increase, traditional cooling systems are struggling to keep up. Water cooling is a concern for many data center operators. However, the heat transfer rate of water is about 3-4 thousand times that of air so the efficiency of water cooling is compelling.
New equipment, tools and business strategies will rein in run-away IT energy costs, the biggest operating expense in the data center. Data center energy management requires a multi-pronged approach: power-sipping hardware, tools that generate a clear depiction of energy use and expose areas where changes will pay off, and business strategies that bring in the right energy control products with the best return on investment (ROI).
When we took aim at the big green data center purveyors like Google, Apple and Facebook, we had no idea that we’d struck an energy efficiency nerve with data center professionals around the globe. It turns out that yes, everyone’s aware that PUE is a big of a weasel calculation when it comes to energy efficiency. What’s more, data center admins know that greenwashing is prevalent.
