Storage DRS monitors datastore load and can automatically move or place VMs to maintain balance.
vSphere Replication (A) handles data replication, Storage vMotion (C) moves a VM's storage on demand (not necessarily automatically), and Resource Pools (D) manage CPU/memory resources.

The NSX Edge Cleaner tool is typically run on the Edge cluster node VM(s) to clean up the previous configuration and ensure that the node(s) are properly removed before re-deploying the NSX Edge cluster. This process helps to reset the environment and remove any leftover configurations that may affect the re-deployment.

The NSX host overlay VLAN and NSX Edge overlay VLAN must be routed to each other so Edge nodes can establish overlay tunnels with transport nodes.
DNS A records for each NSX Edge node are required for name resolution during deployment and operation.
NSX requires distinct VLAN IDs and subnets for the host overlay network (transport nodes) and the Edge overlay network to segregate traffic and avoid IP space conflicts.
