Link details

Nancy's Grid'5000 linking

Note: All the used fiber cables are dedicated to our Grid'5000 interconnect. When it is said trunk on the above figure it means a more rigid garter.

Loria interconnect

Topology

The Loria laboratory possess a 1Gbit Ethernet network. Service nodes of the cluster are connected to this network. So the 24-port experiment switch, which connects service nodes, makes the uplink to this network.

Nancy's Loria interconnect

Nancy's Grid'5000 cluster is hosted in Loria building. So cabling distance is short. 1000BASE-T technology is used with an RJ-45 CAT6 cable. The 24-port experiment switch is directly linked to the Loria router.

Addressing

Loria uses a public IP address range for its materials : 152.81.0.0/16. Within this range, the subnet 152.81.45.0/24 is dedicated to Grid'5000 cluster:

  • 152.81.45.[101-1??] are dedicated to service node first experiment interface
  • 152.81.44.[201-2??] are dedicated to service node management interface
Note.png Note

Service node first experiment interfaces possess 2 IP addresses:

  • eth0 for cluster's intraconnect: 172.28.53.[1-X]
  • eth0:0 for Loria's interconnect: 152.81.45.[101-1XX]

Naming

Service node interfaces connected to Loria network are also named on it. These names are gathered into grid5000.loria.fr subdomain :

  • fgrillon[1-??].grid5000.loria.fr are dedicated to service node second experiment interface
Note: fgrillon.grid5000.loria.fr, grillon.grid5000.loria.fr and acces.nancy.grid5000.fr are also used for default service node.
  • fgrillade[1-??].grid5000.loria.fr are dedicated to service node management interface
