We may have often heard the environmental organization Greenpeace protests against logging or hunting whales. But there is one environmental organization’s protest that shocked the industry of information and communication technology (ICT), namely their campaign against Facebook’s data center.
Greenpeace is launching a program “Cool IT Challenge” in 2009. One aim urging operators to reduce data center energy use and find solutions to address global warming. Opposition to the data center Facebook Facebook itself triggered the decision to build data centers in Oregon, using electricity from PacificCorp, a generating company which produces 67 percent of its energy from coal.
“Facebook is stepping into the path that will make us increasingly difficult to let go of its dependence on dirty coal-powered plants,” writes Kumi Naidoo, executive director of Greenpeace in an open letter to Mark Zuckerberg, Facebook founder.
The story is a blow to the movement “Green Information Technology” because the reality in terms of energy efficiency, data center Facebook is one of the best in the world. Oregon’s cool climate allows the data center that operates without mechanical cooling which normally absorbs most energy in a data center.
Facebook can only move its data center to a place that provides green electricity (eg from wind, water, or geothermal). But it makes them have to consume more electricity to turn on cooling for the engines is tantamount to waste of energy.
Reflecting of the case, the managers of data centers around the world agree that the green data center can not be realized simply by finding the energy supply of the green plants as well, but should be offset massive energy savings.
“The trend now is to create a green data center. One way is to utilize components that require little energy. That’s one thing that we discuss in the Asia Pacific Council Datacenter in Singapore, this Friday,” said David Fosberg, Vice President of Samsung Asia in an electronic interview with Kompas.com, Friday (16/09/2011).
“The manager of a giant data center in the Asia Pacific region who gathered to find ways to reduce energy consumption, which in turn will lead to cost reductions, and optimize data center performance,” continued Fosberg.
Samsung itself comes with a green solution through the products of his memory, such as DDR3, SSD, GDDR5 and LPDDR2. DDR3 is the memory of data processing, GDDR5 is used to process graphics, LPDDR2 used as memory in mobile devices, while the SSD (Solid State Drive) as a replacement data storage hard disk drives.
DDR3 4GB Samsung claims that are manufactured using 30 nano-meter technology could cut his energy consumption to 86 percent compared to SDRAM that is used on most servers now. This means, if all servers in the world using the DDR3 product, within a year will be saving 95 Tera Watt Hour or the equivalent electricity used to power 8.3 million homes a year.
As for SSD, by Samsung will be 70 percent energy savings in a state of active memory, and 83 percent in idle condition. This is one of them because the SSD does not have the energy used to play such discs on the hard disk drive (HDD). These savings, equivalent to the energy used to light 5.5 million homes a year.
If all servers in the world using DDR3 and SSD, then the combination of the two claims can save 98 Tera Watt Hour or the equivalent energy to power 8.5 million homes a year, aka reduce carbon dioxide emissions from 18 coal power plants for a year.
“The savings in energy consumption is due to green memory products from Samsung to work on a lower heat levels than other memory,” says Fosberg. “Besides being more environmentally friendly, energy savings will also lead to cost savings,” he added.
So as noted above, the use of green energy sources is not enough. What also must think and do is energy savings. And it can be done with technology that makes data center is no longer hungry for energy.
