The workload domain wizard uses two network interface controllers (NICs) during deployment. It requires that only a single vSwitch exist or the wizard will display an error. In order to use a PowerFlex datastore presented using SDC for the workload domain, the volume that backs the datastore must be seen through that network. Supplemental PowerFlex storage can be added post installation through more advanced networking.
