Blue Waters Networking
Blue Waters is comprised of a robust and capable Local Area Network coupled with a redundant Wide Area Network to provide leadership class data transfer capabilities and resiliency. Through active monitoring and data collection this network is kept in optimal performance. To see the network usage charts showing Ethernet network performance between Blue Waters subsystems, out of the Blue Water system, and out to the Wide Area Network, select the link below.
Local Area Network
The NCSA Network Engineering team, working with Cray, provides Blue Waters with external network connectivity which is comprised of an InfiniBand network for interconnecting to the storage infrastructure and with Ethernet infrastructure for connectivity off of the Blue Waters System. The Ethernet network provides 128 ports at 40Gbps with the design that the network will be sufficient to support any traffic the Blue Waters system can generate. This Blue Waters Ethernet network then connects at an aggregate of 400Gbps to the NCSA backbone in a resilient mesh of redundant 100Gbps links between the core and exit routers. This provides a substantial infrastructure supporting scientific discovery.

Yesterday's Top 10 Blue Waters Data Moving Networks
Blue Waters is the source and destination of large data sets. As part of our regular management of the network supporting Blue Waters, we monitor that data over the network. This is the list of the top 10 data moving autonomous systems, or remote networks, in the previous day. The network names and total bytes transferred in the previous day is listed below.
