This Sun BluePrints™ article describes Sun Netra servers and how they were used in a proof-of-concept environment without traditional mechanical cooling systems. In this collaborative effort, Sun and Belgacom engineers demonstrated how to effectively and efficiently cool carrier-grade servers using only ambient air. It covers the following topics:
• "Sun Netra servers and NEBS/ETSI compliance" describes the Sun Netra servers and their * environmental characteristics.
• "Green trends in datacenter design" explores the topic of decreasing energy use in datacenters, highlighting successful strategies and environmental "optimizers" that are helping to reduce datacenter energy consumption.
• "What is "full free air cooling"?" compares and contrasts traditional datacenter cooling techniques with the approach of full free air cooling (FFAC).
• "The FFAC datacenter prototype" describes how Sun and Belgacom engineers collaborated to build a test environment using FFAC. This section also introduces the concept of Power Use Efficiency (PUE) in measuring a datacenter's efficiency with respect to energy use.

Erik Vanden Meersch holds a Masters degree in Engineering and Electromechanics. Before joining Sun Microsystems in 1997, he worked in research and development organizations in several telecommunications companies. He is based in Brussels, Belgium and designs solutions using Sun technology for major customers in the telecom and media industries.
Ravi Sanjeev has more than 19 years of industry experience, nine of which have been with Sun Microsystems. Ravi has served in a wide variety of consulting roles involving hardware, software, systems, and product marketing. Ravi has led many mission-critical engagements for Sun in the telecom and federal sectors. Ravi is currently a Technical Marketing Manager responsible for all aspects of Sun servers that use CoolThreads™ technology. Ravi holds a M.S. degree in Computer Science.
Johan Vanderhaegen holds a Masters in Electrical Engineering and specializes in business management and safety engineering. For over 22 years, he has been active in power supply design and selection. After a first job as an automation engineer with Alvey-Europe, he joined Belgacom in 1987. In 1991 he became responsible for the design of AC and DC power supply usage in technical buildings. Since 1996, he managed the design and maintenance of the power chain for Belgacom's telecom equipment. Since 2008, he has been specifically focused on power conservation and management initiatives.
