Interconnect
Chaos Interconnect
The interconnect is composed of an Infiniband QDR (40Gb/s) network.
The choice of topology is imposed by the heterogeneous nature of Chaos, and by the fact that the hardware is split across 2 server rooms.
The following schema describes the topology of the Chaos Infiniband Network.
Additionally, the cluster is connected to the infrastructure of the University using 10Gb Ethernet.
A third 1Gb Ethernet network is also used on the cluster, mainly for services and administration purposes.
Gaia Interconnect
The interconnect is composed of an Infiniband QDR (40Gb/s) network, splitted in 2 pools, configured in a minhop topology.
The following schema describes the topology of the Gaia Infiniband Network.
Additionally, the cluster is connected to the infrastructure of the University using 10Gb Ethernet. A third 1Gb Ethernet network is also used on the cluster, mainly for services and administration purposes.
G5K Luxembourg site Interconnect
The interconnect is composed of:
- one main router (Cisco 6500), which maintains the link with the French G5K network
- the 10GbE network (using Cisco Nexus 5000 and Force10 switches)
