Before commissioning hosts for a new Workload Domain that will use NFS as the principal storage in VMware Cloud Foundation (VCF), the NFS VMkernel network adapter must be configured. This network adapter is essential for enabling ESXi hosts to communicate with the NFS storage, as it allows the hosts to mount and access the NFS datastore.

For Workload Management in VMware Cloud Foundation, VMware best practices recommend a minimum subnet mask of /24 for the ingress network. This provides sufficient IP addresses (256 addresses) to handle the requirements of Kubernetes services, load balancing, and potential future scaling within the workload domain. A smaller subnet, such as /27, would offer too few addresses and could restrict scalability, while larger subnets, like /22 or /18, are generally unnecessary and may be inefficient.
