IP networks in use

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

Public Networks

• computing : 172.16.128.0/20
• virtual : 10.164.0.0/14

Local Networks

• admin or ipmi : 172.17.128.0.24

Network

Physical view of the compute network

Gigabit Ethernet

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 (from sol-1 to sol-47) have a second Ethernet interface connected to 2 Cisco 3750 stacked switches but they are not activated.

• IP addressing for eth1: sol-{1-47}-eth1, using the 172.16.128.0/24 network ( 172.16.128.154 can be used as a gateway)

The Cisco are interconnected to the main FastIron router with a single 1Gbps link.

	Warning
	The second network is no longer available on sol, as one of the two Cisco switch is dead

Suno Cluster (Dell R410)

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

Topology

The main switch is a Foundry FastIron Super X. It has 2 dual 10GB modules, 4 modules with 24 gigabit ports, and 12 gigabit ports on the management module (so 60 gigabit ports are available). 4 slots are currently free.

The EdgeIron stack (helios) is connected to the FastIron with 2 aggregated 10GB links.

Myri 10G

A subset of the sol cluster (sol-[29-50]) is connected to a 10G Myrinet switch.
