Networking

Arista 10G Core Network

CCR 10G Core Networking

CCR Core Ethernet Network

Core networking for the Center was updated in 2011.  The Center's internal Ethernet network infrastructure is based on an a core Arista 7508 10Gigabit Ethernet switch.  It is an Enterprise class switch, with redundant supervisor engines.  The switch has four 48 port 10GigE blades.  All ports on the switch can run at the full 10Gigabit line speed.  Core infrastructure hosts and Network Attach Storage are directly connected to this core Arista switch.  Compute nodes connect to Dell Powerconnect 6248 edge switches with either two or four 10GigE uplinks to the core Arista.

The Center also has two Arista 7048 edge switches with 48 GigE ports and four 10GigE ports connected to the core Arista switch.  These two switches support management related hosts and some one-off departmental servers.

CCR Cluster Interconnects

The Center's clusters contain several high-performance low-latency networks used for interconnecting nodes within the clusters.  The u2 cluster has 256 nodes connected with an older Myrinet network.  New IBM and Dell nodes are all connected by Infiniband networks.  See the U2 hardware page for more details and information on how to run on these particular networks.

UB & NYSERNET Networking

UB & NYSERNET Networking

Through New York State's advanced research network (NYSERNet), CCR and UB have access to all major high speed communication networks commonly referred to as the Next Generation Internet. NYSERNet leverages commercial connectivity for its member institutions, provides dedicated access to dark fiber, and a host of other services.
