ADVA Optical Networking, Obsidian Strategics Inc. and Voltaire Ltd. today announced an integrated capability to extend InfiniBand connections to 50km without performance degradation. The solution was successfully tested at the University of Stuttgart’s High Performance Computing Center (HLRS), which provides systems, tools and expertise for public and private supercomputing development projects. The HLRS solution comprised the following elements. More than 500 computing nodes of the new Baden-Württemberg Grid Cluster were clustered via two 288-port Voltaire Grid Director 2012 switches. They were interlinked using Obsidian's short-reach Longbow Campus devices for serializing and range-extending the 4X SDR InfiniBand signal. The ADVA WDM FSP devices (FSP 2000 or FSP 3000) were then used to interconnect the sites using protocol-agnostic, Dense Wavelength Division Multiplexing (DWDM) that provided bit-transparent, lowest-latency transport. The whole solution was built using generally available devices.
