Sophia Network

Gigabit Ethernet

Azur Cluster (IBM e325)

All the nodes are connected to 4 Cisco-3750 switches (gigabit ethernet). The switches are interconnected using a 32Gbps stack. The nodes are connected to the following switches:

  • switch n°9 (Master) : node-1 to node-15 (15 nodes), 10GB uplink

to the FastIron

  • switch n°8 : node-16 to node-36 (21 nodes)
  • switch n°5 : node-37 to node-55 (19 nodes)
  • switch n°6 : node-56 to node-74 (19 nodes)

The switches are dedicated to Grid5000 (since january 2007; before that, they were shared with the local cluster).

You can choose the switch for your reservation with OAR, using the switch number: oarsub -l nodes=15 -p switch=X

Helios Cluster (Sun X4100)

All the nodes are connected in gigabit ethernet to 2 Foudry EdgeIron switches (one Edgeiron 48GS and one EdgeIron24GS). The switches are interconnected using a 2x10Gbps stack (10GBps in each direction). The nodes are connected to the following switches:

  • switch n°1 : helios01 to helios48 (48 nodes)
  • switch n°2 : helios49 to helios56 (8 nodes)

You can choose the switch for your reservation with OAR, using the switch number: oarsub -l nodes=15 -p switch=X

OS used: 2.2.6.35

Sol Cluster (Sun X2200 M2)

All the nodes are connected (in a non blocking way) to the main Foundry FastIron Super X switch.

47 nodes have a second Ethernet interface connected to 2 Cisco 3750 stacked switches.

Topology

The main switch is a Foundry FastIron Super X. It has 2 dual 10GB module and 2 24 gigabit ports modules.

The Cisco 3750 stack (Azur) is connected to the FastIron switch with a 10GB link; The EdgeIron stack (helios) is connected to the FastIron with 2 aggregated 10GB links.

Each frontend is connected to the FastIron switch.

Myrinet

74 azur nodes and 54 helios nodes are connected to the 128 ports Myrinet 2000 switch.

You can submit jobs with OAR on Myrinet nodes using the 'myrinet' property: oarsub -l nodes=10 -p "myrinet='yes'".
