  • 1 commutation card Flextronics F-X43M204
  • 12 line cards 4X 12 ports DDR Flextronics F-X43M203

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.

Infiniband 56G on graphite/graoully/grimoire/grisou nodes

  • graoully-[1-16] have one 56GB Infiniband card.

  • Documentation
  • 36 FDR (56Gb/s) ports in a 1U switch
  • 4.032Tb/s switching capacity
  • FDR/FDR10 support for Forward Error Correction (FEC)

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.
