High Performance Networks

Infiniband 20G on griffon nodes

Nodes

• griffon-1 to griffon-92 have a 20GB Infiniband card.

• Card Model : Mellanox Technologies MT26418 [ConnectX IB DDR, PCIe 2.0 5GT/s] ( ConnectX ).
• Driver : mlx4_ib
• OAR property : ib20g=1 ( Monika ).
• IP over IB addressing : grelon-[1..92]-ib.nancy.grid5000.fr (192.168.210.1 à 192.168.210.92)

Switch

• Infiniband Switch 4X DDR
• Model based on Infiniscale_III

Interconnection

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.

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.
