Starting with Cloud Foundation 3.9.1, you can isolate vmkernel traffic (management, vSAN, vMotion, or overlay) across multiple physical NICs (pNICs). You can enable four pnics per host in NSX for vSphere workload domains, and up to six pnics per host in NSX-T workload domains. Each vDS supports two pNICS, so you must define additional vDSes and map traffic per vDS as appropriate. This capability is available for Cloud Foundation 3.9.1 deployments or when upgrading to Cloud Foundation 3.9.1.
- Management domain (by using these hosts in the Cloud Foundation bring-up process)
- Creating VI workload domains
- Adding clusters to the management domain or VI workload domains
- Adding hosts to a cluster
For multi-pNIC use cases and API examples, see About Using Hosts with Multiple Physical NICs with VMware Cloud Foundation.
- four pNICs (one vDS and one N-VDS)
- six pNICs (two vDS and one N-VDS)
Traffic isolation across physical NICs is not supported through the UI. You must enable the additional pNICs on hosts before commissioning them to Cloud Foundation. You can then update the API spec to map traffic flow to reflect your physical topology. For information on using APIs, see VMware Cloud Foundation API Reference Guide.
