Slovak Telekom will use IBM to build a new green data center in Bratislava, Slovakia and it is targeted to begin operations in 2011 enabling capacity growth needs. The data centre will leverage ambient outside air for cooling and implement high-density rack arrangements that optimize cooling system efficiency. …

… “The data centre will be built on approximately 1,200 square meters of a modern, five-floor building, providing a highly-resilient environment. It will be fully equipped to protect Slovak Telekom‘s valuable information technology investments. It will ensure the highest levels of physical and digital protection, including access control, CCTV, intrusion, fire and flood detection and extinguishing systems, as well as, comprehensive monitoring of the IT infrastructure. Green techniques include a cooling system which, during cold months, will leverage outside air, reducing the need for air conditioning units. The high-density layout of the centre will ensure that IT equipment is sectioned according to heat emissions in order to optimize cooling capacity and efficiency. ” …

UPS takes sustainability personally. The company has published its Corporate Sustainability report and provide transparency to the actions it is taking to transform its carbon footprint. The company has already seen the benefits of data center efficiency through implementation of opportunities, classified as “low-hanging fruit”. Expect UPS to continue to raise the bar and be an industry champion for sustainable development. …

UPS Sustainability Program provide report on performance to date

… “We have managed to reduce annual electricity consumption by nearly three million kilowatt hours at Windward Data Center through innovative use of simple but powerful elements: air and water. In one case we re-engineered airflow to adjust hydrostatic pressure and keep cool air where it belonged: surrounding the server racks. That change alone produced a saving of 1.5 million kilowatt hours of electricity. ” …

Limit Mixing to Cool Data Center with Less

Posted in adaptiv-cool, air-conditioning, air-flow, airflow, cooling-system, data-centers, efficiency, floor-space, mixing on May 28th, 2009 by FrankM – Comments Off

Efficiency is a powerful lever for existing data centers. There is a good chance that your cooling system is oversized for the situation and yet the computer equipment is not being cooled fully. Look to reduce mixing of warm and cool air and implement variable cooling to optimize the cooling requirements. …

… “The primary reason cited for this inefficient cooling is a phenomenon known as mixing where cool and warm air mix before entering server intakes. Recent studies from various industry groups agree that managing airflow and reducing mixing can cut data center cooling costs dramatically and even eliminate the need to build new sites. ” …

The future for data center cooling
Rittal shares its views on the future opportunities for green data centers and envisions possibilities for data centre cooling via solar energy technology. …

… “For this purpose, adsorption refrigerating machines in connection with solar heat collectors convert the energy from the sun into cold water which is used for air-conditioning the data centres. Especially regions with intensive solar radiation allow the use of solar energy all year long. The use of regenerative energies for air-conditioning data centres saves primary energy and CO2. Further savings are possible by a combination with free cooling. ” …
