IP networks in use

You have to use a public network range to run an experiment between several Grid5000 sites.

Experiment network

Infiniband network

As seen in the physical network overview, Infiniband network is physically isolated from Ethernet networks. Therefore, Ethernet network emulated over Infiniband is isolated as well. There isn't any interconnexion, neither at the data link layer nor at the network layer.

A local network is used to address all griffon nodes emulated ethernet interfaces (griffon-nn-ib in production environment):

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.

Management network

The following DEPRECATED diagram show the experiment network and the administration network, to have a globlal view. Services node connections are logical.

Admin network - DEPRECATED

The following diagram show a view of the central router, a hp procurve 5406zl, named sgravillon1.

  • All internal links are 10GB CX4.
  • Renater link is 10GB optical fiber.
