NSX Load Balancer

NSX supports 2 types of load balancer deployment:
Inline or Transparent mode
One Arm or Proxy mode


            – Inline/Transparent mode cannot be deployed in Active – Active mode with ECMP enabled.
– One Arm/Proxy mode is the option for deploying load balancer functionality when Edge Gateways are deployed in ECMP

One Arm Mode/ Proxy Mode:

  • Separate instance of Edge Gateway is deployed for load balancing functionality.
  • Edge Gateway uses the single interface which will be the VIP for the servers in the server pool.
  • The VIP is in the same subnet as the server pool server’s subnet.
  • The logical routers will be the Default Gateway (D.G) for the members in the server pool.
