An SFS with VxRail and VCF deployment requires the following:

• All SmartFabric leaf and spine switches must be running OS10.5.4.5 or a later version listed on the Dell Networking Support & Interoperability Matrix.
• VxRail nodes must be running VxRail 7.0.400 or a later version listed on the Dell Networking Support & Interoperability Matrix.
• VCF software must be version 4.5 or a later version listed on the Dell Networking Support & Interoperability Matrix.
• VCF and VxRail versions must be compatible as shown in Supported versions of VMware Cloud Foundation on VxRail.
• SmartFabric Services and a single four-node VxRail cluster is deployed for the management domain per Dell Networking SmartFabric Services Deployment with VxRail 7.0.400 with the following configuration settings:

• Automated switch configuration is set to Disabled during VxRail deployment. For more information about this setting, see New Deployment Option for SmartFabric Services with VxRail.
• An NTP server IP address is specified during VxRail deployment.
• VxRail Management Network port binding is set to Ephemeral Binding during deployment.
• Layer 3 uplinks are configured from the SmartFabric leafs to the external switches.

• Other VxRail nodes, not yet deployed, are available for one or more VCF workload domains as needed. For VCF workload domains, the Software-Defined Data Center (SDDC) Manager is used to deploy VxRail instead of the VxRail Deployment Wizard.
• At least one DNS server that is reachable from the external management networks with host records added for this deployment.
• At least one NTP server that is reachable from the external management networks.
• At least one DHCP server per the example in this guide that is reachable from the NSX host overlay networks (recommended). The DHCP server is used for NSX host overlay network (tunnel end point) TEP IP address assignments. A static IP address pool may be used instead of a DHCP server, with limitations described in VMware Cloud Foundation 4.5 on Dell VxRail.
