GreenStar Network Project Uses Green Energy Resources to Power Network Infrastructure
GEANT is the high bandwidth pan-European research and education backbone that interconnects National Research and Education Networks (NRENs) across Europe and provides worldwide connectivity through links with other regional networks. It has helped create a new network that uses a combination of software, renewable energy resources and the GEANT network infrastructure to help create the GreenStar Network (GSN) project, which uses green energy resources to power network infrastructure.
The project’s aim is to develop green ICT technologies based on resource virtualization and Infrastructure-as-a-Service to create networks with a zero-carbon footprint. A cloud-based infrastructure ensures the maximum amount of green energy is used at any one time.
The network has four international nodes inside European data centers which are powered solely by renewable energy. Two of the data centers are run in Ireland by NREN HEAnet, which use a combination of solar and wind power.
The GSN relies on the high capacity, pan-European GEANT network to transmit this vital monitoring data in real-time, using a mix of dedicated point to point circuits as well as GEANT's Bandwidth on Demand (BoD) multi-domain connectivity service. BoD enables the fast, automatic creation of dedicated high speed links between different network points within minutes, providing guaranteed bandwidth for the GSN.
GreenStar Network project instigator Mohamed Cheriet said the project is based on a virtualized green architecture that relies heavily on automatic bandwidth provisioning.
“The GreenStar Network aims to demonstrate that it is possible to reduce the carbon footprint of ICT without decreasing performance,” Cheriot said. “The techniques and technology within the GSN project have far-reaching potential to reduce emissions, but none of this would be possible without flexible, high performance international research networks such as GEANT to provide the real time monitoring and control needed to deliver a virtualized green architecture.”
GSN used monitoring and control software provided by the Mantychore open source project to distribute data processing and traffic loads between the four nodes.
The Canadian NREN CARNARIE has funded the GSN project, and created a self-contained network that features automatic bandwidth provisioning across multiple networks using the four European nodes in October 2011.

As the need to balance current and future IT requirements against resource consumption becomes more urgent, the data center industry increasingly views capacity planning as a way of achieving a critical component to planning a new build or retrofit. Data center capacity planning can be a complex undertaking with far-reaching strategic and operational implications. DCD Intelligence has therefore compiled this White Paper in order to share some industry insights and lessons on the practical steps that are needed to develop a successful power and capacity planning strategy.[Read More]
Server Technology had the recent opportunity, along with other partner companies, to participate in discussions across the globe with data center IT and facility managers as part of a road show seminar: Data Center Energy and Operational Efficiency.[Read More]
The demand for more power in the computer cabinet has led many data centers to upgrade to three phase power distribution. Proper three phase power distribution has traditionally meant dividing up power up into multiple branches within the rack PDU (Power Distribution Unit). In this paper we will explore the advantages of a new, less common approach to PDU design by means of alternating each phase on a per-receptacle basis instead of a per branch basis.[Read More]
Increasing powering and cooling demands within the data center have been the topics of choice for Data Center (DC) and Facility Managers for several years now. Increased power demands are a result of the need for more compute power and higher density devices have resulted. These high density installations include stacks and stacks of servers and the trend of implementing blade servers within these server "farms." Cooling problems are a direct result of the increased power demands based on the simple fact that more power increases the demand for cooling.[Read More]
