Data center core network physical connectivity

  • Each of the Dell EMC switch models that are supported for SFS with VxRail includes ports targeted for uplink connections to the data center network.

    • You can choose the egress point from the SmartFabric infrastructure to your upstream core network at either the leaf layer, spine layer, or with dedicated border switches per the selected network topology.
    • Changing the upstream connectivity option between the leaf layer and spine layer if the SmartFabric-enabled network expands from a leaf-only architecture to a leaf-spine architecture is supported.
    • For the ports on the switches targeted for upstream connectivity, the 100GbE Ethernet ports on the Dell switches are based on QSFP28 and the 40GbE ports are based on QSFP+.
    • If the 100 GbE or 40 GbE ports are not compatible with the planned data center network, port breakout is supported on the Dell EMC Ethernet switches for VxRail with SFS. The port breakout feature reconfigures selected 40 GbE ports to run at 10 GbE speed, or reconfigure selected 100 GbE ports to run at either 25 GbE, 40 GbE, or 50 GbE. This feature can be set from the user interface derived from SmartFabric control switch.
    • See the Dell Networking Optics Specification Sheet for complete details on qualified cables and adapters for Dell EMC Ethernet switches.
