Grid5000 interconnect

Interconnect type

Link details

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 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
	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
