Demo Leverages ESnet’s Transcontinental Advanced Networking Research Initiative (ANI) Testbed and Multi-Vendor Participation to Demonstrate RDMA-Enabled Data Transfer, Spanning Approximately 7,000 Miles
Seattle, Washington – November 14, 2011 – Today at Supercomputing 2011 (SC11), the international conference for high performance computing, networking, storage and analysis, researchers from Orange Silicon Valley, The Department of Energy’s Energy Sciences Network (ESnet), InfiniBand Trade Association (IBTA) and OpenFabrics Alliance (OFA) join forces with the SC11 conference network SCinet to showcase the world’s first demonstration of a Remote Direct Memory Access (RDMA)-enabled data transfer at 40 Gigabits per second (Gbps) over wide area network links spanning approximately 7,000 miles.
This experiment marks the first time that RDMA has been demonstrated at 40Gbps data rates for such a long distance, showcasing the technology’s ability to improve performance for bulk data transfer in the wide area. The demonstration illustrates three usage models of RDMA at such a distance: the ability to move multiple simultaneous data streams; the ability for a user to access a remote data set as though it were locally mounted; and the ability to move large file transfers at high bandwidths. The RDMA protocols in the wide area enable the three usage models to achieve up to 96 percent utilization of the available bandwidth in the network.
During the demonstration, SC11 attendees will see firsthand how RDMA enables servers in the local nodes to transfer data to or from application memory, eliminating the overhead of copying data between application memory and the data buffers in the operating system. When an application performs an RDMA operation, the application data is delivered directly to the network, eliminating the additional latency the transfer would incur if the data were to be copied into the operating system memory buffers. This dramatically increases the application-messaging rate and the application processing efficiency of the servers from approximately 20 percent up to 80-90 percent.
“RDMA communication opens new possibilities for collaboration among researchers by enabling quick and efficient data sharing,” said Jim Ryan, chair of the Open Fabrics Alliance. “By eliminating many of the typical network performance bottlenecks, users make more efficient use of their WAN, cloud and data center infrastructures.”
The demonstration was conceived this past summer when Orange Silicon Valley, a subsidiary of France Telecom-Orange, an international operator for mobile and broadband Internet services and one of the world leaders in providing telecommunication services to multinational companies, partnered with ESnet and Bay Microsystems to perform the first field trial of this technology demonstrating RDMA protocols over a 40Gbps WAN over a distance of 230 miles. The success of that field trial encouraged Orange Silicon Valley and the collaborators to consider longer distance trials at SC11, leveraging the SC11 SCinet Research Sandbox (SRS), a conference program, which provides a venue for network researchers to showcase disruptive innovation in an experimental network environment.
Orange Silicon Valley successfully submitted a proposal to the SCinet SRS to showcase this technology at SC11, choosing the OFA and IBTA booth based on both consortiums’ vision of embracing open standards. The SC11 demonstration – including technology from members of both the IBTA and OFA – leverages ESnet’s nationwide ANI Testbed which is being made available to researchers both in the public and private sector as a first of its kind platform to test experimental approaches to new network protocols and architectures in a greater than 10 Gbps network environment.
“This collaboration at SC11 between Orange Silicon Valley, ESnet and members of the IBTA and OFA enables a unique environment for demonstrating the benefits of globally scaling out and deploying RDMA-enabled applications,” said Brian Sparks, co-chair of the marketing working groups of the IBTA and OFA.
The following member companies provided hardware, software, architectural and/or operational expertise in this demonstration: 3M, Bay Microsystems, Chelsio Communications, DataDirect Networks, Finisar, HP, Mellanox Technologies, NetApp, Software Forge, System Fabric Works and Volex.
