High Performance Networks

Ethernet 10G on graphite nodes

Nodes

• graphite-1 to graphite-4 have one 10GB Ethernet card.

• Card Model : Intel X520 DP 10Gbit/s connexion directe/SFP+ + I350 DP 1Gbit/s.
• Driver : ixgbe

Infiniband 20G on griffon nodes

Infiniband has been removed from this nodes

Infiniband 20G on graphene nodes

Nodes

• graphene-1 to graphene-144 have one 20GB Infiniband card.

• Card Model : Mellanox Technologies MT26418 [ConnectX IB DDR, PCIe 2.0 5GT/s] ( ConnectX ).
• Driver : mlx4_ib
• OAR property : ib20g=YES ( Monika ).
• IP over IB addressing : graphene-[1..144]-ib0.nancy.grid5000.fr ( 172.18.64.[1..144] )

Switch

• Infiniband Switch 4X DDR
