  2. NCCS network roadmap Summary: Hybrid Ethernet/Infiniband (IB) network to provide both high-speed wide-area connectivity and uber-speed local-area data movement • 2007 • Scaled Ethernet to meet wide-area needs and current day local-area data movement • Developed wire-speed, low-latency perimeter security to fully utilize 10Gb production and research WAN connections • Began IB LAN deployment • 2008 • Continue building out IB LAN infrastructure to satisfy the file system needs of the Baker system • Test Lustre on IB/WAN for possible deployment • Increase security on 10Gb WAN connections

  3. NCCS network roadmap summary Ethernet core scaled to match wide-area connectivity and archive Infiniband core scaled to match central file system and data transfer Lustre Baker Gateway Ethernet [O(10Gb/s)] Infiniband [O(100 Gb/s)] Jaguar High-Performance Storage System (HPSS)‏ Viz
