This poster offers a visual representation of the logical topology of the components comprising the CRD. See https://vmware.com/go/vcat for more information.

  • The Management infrastructure cluster is prepared for NSX to allow deployment of NSX Edge Gateways. It uses both VLAN and VXLAN backed networks but does not use DFW.
  • Only management components included within the CRD are shown. Others may be included in line with local requirements
  • Networks have been combined for visual clarity. Separation of different traffic types using VLAN or VXLAN is assumed.
  • Tenant management is shown using a back-end connection to a dedicated interface on the Tenant Edge. Alternative management access techniques are equally valid.
