General Notes

Full HDR connectivity between switches and HDR100
connectivity to the compute nodes. Half of nodes
in a rack (44) connect to      22 downlinks of a
chassis switch as pairs of HDR100 links into
HDR200 ports of the chassis switch. The other 18
ports are uplinks to the six central switches.
