Testing of Lustre File System Over Wide-Area Connections

USN provides dedicated wide-area layer-2 and SONET connections of lengths rangining from 500 miles to 5000 miles to support testing of Lustre file system. Currently, two resarch teams from Pacific Northwest National Laboratory and California Institute of Technology are testing Lustre file system over TCP/IP connections over USN; their host and file system form complementary configurations. The challenge in Lustre system over TCP/IP connections has been at least in part in optimizing the performance of underlying TCP/IP transport. Research team at National Leadership Computing Facility at Oak Ridge National Laboratory has been working on assessing the performance of supporting Lustre file system using Infiniband over SONET using USN. This configuration represents a non-TCP/IP option for wide-area Lustre file implementation.

These activities are current at different stages, and the results will be posted upon the completion of tests and analysis.
