Network topology
- Cisco 3750 switches have a 64Gb switching capacity, and they are stacked with a 32Gb bus. The uplink of each Cisco 3750 stack is a gigabit optical fiber.
- HP Nodes are connected with HP ProCurve 2848 switches.
- The 10Mb hub of Sun nodes connects the Service Processor of Sun nodes to the
parasol-srvhead node. - Grid'5000 and Renater connectivity is provided by a Juniper M20 router.
Node names
- Head nodes are assigned to compilation, debugging and running reservations through OAR.
- Compute nodes must be reserved before use with GridPrems or OAR.
