Webinar: Managing Data Center Power & Cooling
1/15/2008, 1 PM EST ( -5 UTC/GMT)
Moderated by: Brian Cashman, Internet2 Network Planning Engineer
Presented by: Jeremy Stieglitz, Director of Marketing Force10 Networks

Optimizing the overall power efficiency of the high performance computing centers requires a comprehensive approach that focuses on technologies and strategies to minimize power consumption and maximize power efficiency at every level within the infrastructure, including CPU chips, power supplies, servers, storage devices, and networking equipment. In addition to measures that maximize power efficiency for hardware devices, there are also software strategies, such as server virtualization, that can play a significant role in reducing power consumption.

There are a number of potential benefits that can be derived from an increased focus on power consumption and power efficiency:

• Extending the life of existing data centers and HPC centers and minimizing retrofits
• Gaining at least partial control of growing expenses for power and cooling
• Optimizing new data center designs to be more energy efficient

A team led by Indiana University, with partners from the Technische Universität Dresden, Rochester Institute of Technology, Oak Ridge National Laboratory and the Pittsburgh Supercomputing Center, won first place in an international competition for leading-edge, high-bandwidth computing applications at SC07, the world's largest international conference for high performance computing, networking, storage and analysis. Using the IU Data Capacitor, a system designed to store and manipulate massive data sets, the IU team achieved a peak transfer rate of 18.21 Gigabits/second out of a possible maximum of 20 Gigabits/second. This performance was nearly twice the peak rate of the nearest competitor. The IU team achieved an overall sustained rate of 16.2 Gigabits/second (roughly equivalent to sending 170 CDs of data per minute) using off- the-shelf server hardware, standard Linux TCP/IP stacks and several advanced networks around the world including Internet2, GÉANT2, DFN, NYSERnet, CIC OmniPoP, and Indiana Gigapop.

This fall, the New World Symphony in Miami, Florida performed a classical piece written by David Sampson. Prior to the performance, the piece was rehearsed for the composer--who was hosted at New York University--using DVTS and large-format LCD displays to transmit high quality video and audio between NYU and NWS via the Internet2 Network. The composer watched the performance via DV25 digital video, and offered his feedback to the orchestra. Later that day, a live audience watched a discussion between the conductor and the composer, with the composer appearing "live" on a large LCD display via DVTS. Then, the orchestra performed the piece for the live audience. A video featuring highlights from the event is available online.

On October 11, 2007, Internet2 and Rede Nacional de Ensino e Pesquisa (RNP), the national research and education networking organization of Brazil, signed a new Memorandum of Understanding (MOU) to facilitate international telehealth and telemedicine collaborations. The new MOU builds on the organizations' existing long-term networking partnership that was established in 2000. It provides a pathway for the Internet2 and RNP communities to jointly lead and collaborate on the development of next-generation telemedicine and telehealth technologies and applications. In doing so, the organizations hope to accelerate the adoption of these important technologies within the U.S and Brazil as well as to promote and encourage the continued interconnection of advanced networks around the world in support of telemedicine and telehealth.

RNP is today leading a new project called Rede Universitária de Telemedicina (RUTE). Funded by the Brazilian Ministry of Science and Technology, the project seeks to build and update the communication infrastructure of 57 university hospitals that are connected throughout Brazil with the goal of enabling all participating hospitals to use the RNP network to run telemedicine and telehealth applications including video conferencing for information exchange, second opinion, continuous education and web conferencing.

At the member meeting last week, Internet2 announced the completion of a new nationwide advanced network infrastructure. With an initial capacity of 100 Gigabits per second (Gbps) nationwide and a revolutionary Dynamic Circuit Network (DCN) providing dedicated bandwidth-on-demand capabilities, the new infrastructure provides the potential to transform radioastronomy, telemedicine, network research, and the performing arts. At the meeting, Rick Summerhill, Internet2's chief technology officer, in collaboration with Dale Finkelson and Dr. Carl Lundstedt of University of Nebraska-Lincoln (UNL), together with colleagues from ESnet, Fermilab, and the Great Plains Network, demonstrated the DCN's ability to support the networking demands of high energy physicists collaborating on the Large Hadron Collider experiment. Dr. Lundstedt, with one mouse click, set up a 10 Gbps dedicated circuit between the UNL campus and Fermilab in Batavia, Illinois. The result was that the data traffic flowing across the shared IP network seamlessly switched over to the DCN and quickly transferred one-third of a terabyte of data (equivalent to the capacity 40 standard DVDs).
