IP networks in use
You have to use a public network range to run an experiment between several Grid5000 sites.
Public networks
- only some servers : 131.254.202.0/23
Routed private networks
- computing : 172.16.96.0/20
- virtual : 10.156.0.0/14
Local networks
- IPMI : 172.17.96.0/20
- 10G nets : 172.18.96.0/20 : see High Performance Networks
Network
Experiment Network
- Our network connectivity is provided by a single switch: a Cisco 6509. It provides us with a gigabit ethernet connection to each cluster node, a 10G uplink to Renater and a Gigabit uplink to the IRISA Network (used for DNS/NTP access, and connection to satellite sites).
Node names
- Compute nodes must be reserved before use with OAR on
