More details about the network topology (deprecated)

• 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 frontend.rennes.grid5000.fr
