Load balancing is not working within an environment.

Issue:

Load balancing is not working within an environment.

Cause:

  • An Internet service has not been created.
  • One of the servers' NIC drivers has been updated.
  • Persistence setting on the Internet service has maintained stickiness to other nodes.
  • Traffic is originating from a single IP address.

Workaround:

  • An Internet service has not been created.
  • An Internet service must be associated with a public IP address and the virtual machines must be attached to that Internet service as node services.

  • One of the servers' NIC drivers has been updated.
  • Have the customer:

    1. Connect to the server from Infinicenter Console.
    2. Disable the NIC associated with the node service.
    3. Restart the virtual machine, if possible but not required.
    4. Connect to the server from Infinicenter Console.
    5. Enable the NIC associated with the node service.
    6. Test load balancing.

  • Persistence setting on the Internet service has maintained stickiness to other nodes.
  • Reset persistence on the Internet service.

  • Traffic is originating from a single IP address.
  • In some cases, customers test load balancing using third party software where the testing software generates traffic from only one or two IP addresses. Depending on the load balancing algorithm, this can cause the traffic to always go to the same server.

    Try testing software that uses multiple IP addresses.
