A First Long Distance Link 40 GbE
From Amsterdam to Geneva, the 40 GbE network has passed a reliability test, has sent computer images of the “Big Bang” on a video wall of 15 high-definition displays. A world premiere that opened the door to many applications for research, data centers, the mainstream media, the video game industry. Update on this innovation.
“The new 40 Gigabit Ethernet technology is the guarantee of unlimited possibilities,” says Jan. Hof, Senior DirectorField Marketing EMEA at Extreme Networks switching successful first 40 GbE network long distance between the center Sara Computing and Networking Services in Amsterdam and the European Center for Nuclear Research (CERN) in Geneva. “In addition to applications in astrophysics, consumer multimedia solutions or the video game industry booming, the 40 GbE connectivity portends tremendous benefits for science and research. In telemedicine, for example, 40 Gb connectivity allows real-time exchange and over long distances from large amounts of data generated by modern 3D MRI scanners. A doctor based in Amsterdam, Washington and Beijing can share high-resolution images of a microscope with thousands of students worldwide. A pathologist will study European and remotely identify a sample of hazardous biological organism collected in the tropics, without delay and without the risk of transporting it. “
A growing number of research projects involving power forward quickly large volumes of data. This is the case, for example, the Human Genome Project or initiative JIVE processing raw data from radio telescopes around the world. But today, broadband connections to low latency can transmit the data to centralized data centers, which advantageously replace disks, slow and expensive.
40 GbE connectivity also offers media companies more options and flexibility for a much more affordable cost. In addition to eliminating the high costs of transportation equipment and records, the distributors will in fact be able to distribute their films on cinema screens streaming HD and 4K quality stereo.
During this switching is a world first, the graphics of a video of the “Big Bang” project for Astrophysics CosmoGrid were released on 15 screens LCD HDTV. This test was carried out with the 40 GbE switching technology based on standards of Extreme Networks. “This association could not be established without the Extreme Summit X650 switches,” says Dr. Paul Wielinga, manager of the Department’s high-performance network Sara. “Being able to remotely view large amounts of distributed data is one of the major challenges we face at the time of petabytes. This test demonstrated the reliability of the transfer of critical data over long distances at a speed of 40 Gigabit Ethernet switches using standardized, this at a very reasonable price. “
40 GbE links were switched broadband through new modules VIM33 40G4X 40 Gigabit Ethernet Switch Extreme Networks Summit X650. They were established by lambda connection to 40 Gbit / s fiber optic cable between platforms NetherLight CERNLight Amsterdam and Geneva. CERN side, another Summit X650 switch ensured the transmission of data to eight servers and 15 screens in high-resolution component video wall. Each server generates two data streams at 2 Gbit / s to destination 2 screens, giving a record at 22 frames / sec and a total resolution of 12,800 x 4,800 pixels. For testing purposes, cosmological data generated in the Netherlands by five supercomputers in the world, including the Dutch Huygens Sara Computing and Networking Services, has been transformed into visual information using a graphic rendering cluster consisting of 16 servers. This data is currently stored at the center of Amsterdam Sara on 32 SSDs connected to a single streaming server.
“The 40 GbE connectivity from the heart of the network switches to the Top-of-Rack will enhance the performance and capacity scalability expected from the network, in a context where server density is increasing in data centers, because of consolidation initiatives and virtualization. 40 GbE connectivity to the switches Top-of-Rack is even more essential now that the servers tend to support the native 10 GbE. Our offers 40 GbE will enable our customers to evolve their data center cost-effectively to support network migration from physical to virtual network, then to the cloud, “concludes Jan Hof.
