This guide starts with VxRail and OMNI already deployed as instructed in the Dell EMC Networking SmartFabric Services Deployment with VxRail guide. A single or multirack SmartFabric with one or more VxRail clusters may be used for this deployment. The example in this guide uses a two-rack SmartFabric with one four-node VxRail cluster. Uplink connections from the SmartFabric to the external switches are Layer 3, as shown in SmartFabric topology with connections to VxRail nodes and external network. Configuration of uplinks and external switches are detailed in the above guide.
