Overview of Ethernet network topology
Network devices models
- gw: Dell S5296F-ON
More details (including address ranges) are available from the Grid5000:Network page.
Omni-Path Topology
Nodes of the dahu, yeti and lama clusters are connected to Omni-Path switches (Intel Omni-Path 100Gbps), beside the Ethernet network.
This Omni-Path network interconnects both the Grid'5000 Grenoble nodes and the nodes of the HPC Center of Université Grenoble Alpes (Gricad mésocentre).
The topology used is a fat tree with a 2:1 blocking factor:
- 2 top switchs
- 6 leaves: switchs with 32 downlinks to nodes and 8 uplinks to each top switch (48 ports total)
All 32 dahu nodes are connected to a same leaf. The 4 yeti nodes are connected to another leaf. TBC for lama.
A generated topology (using the output of opareports -o topology :
