Green data center
Mobile devices and web services are growing cloud computing at a dizzying pace. How clean are these clouds? We've been tracking this issue since 2010. Here are our latest updates.
Equipment and cooling are the two big targets for reducing energy consumption in ICT facilities. Operators who really want to drive PUE have to look at all areas of consumption and facility lighting is no exception. Lighting consumes energy directly and produces ambient heat that also increases the cooling load. Here's a look at what facility designers and operators are doing.
New ICT facilities implementing the latest in Green ICT technologies and practices garner much publicity, yet a lot is being done with existing ones. The latest post looks at what a major financial services company accomplished through interdepartmental cooperation.
The convergence of multiple lines of Green ICT inquiry is a sign of Green ICT progress. We have covered the growing use of fuel cells to power ICT facilities and the advancement of DC distribution inside the data center. A recent demonstration brings these two concepts together to improve energy efficiency and reliability.
Bitcoin is an extra-sovereign currency which maintains is scarcity by requiring increasingly complex computer calculations for their creation. This process - bitcoin mining - highlights a number of Green ICT issues. Increased public awareness of Bitcoin could help awareness of Green ICT.
Several companies have been working to create cloud computing volume servers using "wimpy chips". These are low-power, lower-speed chips designed for mobile devices. The idea is that large numbers of these in a server can yield lower energy consumption while maintaining cost-effective performance. The EU has launched an initiative using the wimpy-chip approach, but an American pioneer has shuttered its doors.
The industry has been striving to green data centers for some time. Here are some of pioneers from 2002 through 2009.
Much Green ICT focuses on computers: servers in the data center and desktops in the office. Don't forget that disk-based data storage, which can cost an organization $25/GB/month, also offers opportunities. Here's a look at the progress manufacturers and users have been making in recent years to manage data storage's energy consumption. The storage capacity of the United States National Security Agency's (NSA) new data center in Utah is a powerful reminder of the role storage plays in ICT facilities.
The NCAR-Wyoming Supercomputing Center (NWSC) in Wyoming "provides advanced computing services to scientists studying a broad range of disciplines, including weather, climate, oceanography, air pollution, space weather, computational science, energy production, and carbon sequestration. It also houses a landmark data storage and archival facility that will hold, among other scientific data, unique historical climate records." It has also become of the focus our largest Twitter discussion of the 2013.
City governments can show Green ICT leadership. Paul Kronberger, CIO of Madison (WI-USA), a city of 270,000 residents, tells me the municipality has taken these steps to improve the sustainability of its own operations.
