Green data center
Vertatique posts have covered the attraction of locations that offer renewable energy, typically a combination of hydroelectric power and free air cooling from a temperate/cold climate. But about data centers in sunny climates? The question provided a good opportunity to check in on solar photovoltaic electricity (solar PV) back in 2009.
We're increasingly seeing data centers promote, and customers respond to, Green ICT features. Here are some customer perspectives and the results of a industry survey that reveals geographical differences.
Evidence of Green ICT on the information and telecommunications industries is everywhere. Gear is becoming more energy efficient, renewable energy is increasingly in favor, and product content and lifecycles are starting to be scrutinized. So what defines "eco" gear in 2012?
Apple's 2012 Facilities Report provided detail on on the sustainability features, ranging from 'free air' cooling to real-time power monitoring, in Apple's Maiden (NC-USA) data center. A more recent report commits to 100% renewable energy.
A Pike Research report says that the trend to greener data centers will yield a significant GHG slowdown as well as drive a substantial market opportunity. Here are some of the top-line numbers from Pike.
Facebook mentions in passing that its highly efficient Prineville data center uses "Ethernet-powered LED lighting [to] reduce the total energy required to run the facility." Additional information about what exactly Facebook has done is hard to fine. What is Ethernet-powered LED lighting?
Photovoltaic (PV) solar is promising source of on-site renewable electricity generation for ICT infrastructures. Solar PV generates DC power; computers and other e-devices run on DC power. What are the challenges and opportunities?
Oracle's latest Next Generation Data Centre Index compares today's situation ("C2") with that of a year ago ("C1") for Europe and the Middle East. Findings are positive but mixed from a Green ICT perspective.
We first looked at the impact of social media in 2007 with Virtual Worlds Leave a Real World Carbon Footprint. Since then, there has been increasing focus on the mega-data centers that underlie the most popular services. Facebook, who has opted for a custom server approach to reducing PUE, has take the unique step of publishing its server and facility designs. Facebook calls this the Open Compute Project (OCP). The Project just picked up a surprising ally - Greenpeace.
The Green Grid released a survey of data centers' use of economizers, cooling technologies that take advantage of favorable outdoor conditions (air and/or water) to provide partial or full cooling without using a refrigeration cycle. Fifty percent reported that they were already using economizers, but it is not clear that economizer use translates into overall data center energy efficiency.
