Note: The storage requirement per appliance is doubled during the HCX upgrade and redeploy operations, as a second appliance is created for the duration of the operation.

The other HCX virtual appliances deploy per service mesh.

The network extension appliance (HCX-NE) has a one-to-one relationship to a distributed virtual switch (DVS).
