Blue Waters Networking
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 480Gbps to the NCSA backbone in a resilient mesh of redundant links between the core and exit routers. From there, Wide Area Network (WAN) connectivity is provided to multiple local and national Research and Education (R&E) networks at 10Gbps and 100Gbps to provide vast redundancy to distributed WAN ecosystems.
