13 VxRail Networking Guide with Dell EMC S4148-ON Switches | version 1.0
As the customer’s environment grows with added VxRail nodes, a basic topology can quickly scale up to 32
server nodes while utilizing only 64 x 10GbE ToR ports (32 x 10GbE ToR ports per switch) for connecting to
the server nodes. The 2 x 100GbE ports on the S4148-ON use ISL ports and upstream connectivity for a
potential 2:1 oversubscription ratio
2.1.3 Dual-switch topology with Z9100-ON switches
In this setup, the Dell EMC S4148-ON switches are the ToR switches, and the Z9100-ON switches are the
upstream switches. The links to the upstream switches (Z9100-ON) are utilizing 100GbE.
