Add a backup

  1. Right-click the High Availability icon.
  2. Select Add High Availability Backup.
    The High Availability feature involves the use of a second Load Balancer machine. The first Load Balancer machine performs load balancing for all client traffic as it would in a single Load Balancer configuration. The second Load Balancer machine monitors the health of the first and takes over the task of load balancing if it detects that the first Load Balancer machine failed.
  3. In the dialog box, type the port number for the heartbeat messages.
  4. Select a role:
    • Primary: sends connection data to the backup machine on an ongoing basis.
    • Backup: machine is in a standby state, continually updated and ready to take over.
    • Both: If the backup machine detects that the active machine has failed, it will take over and begin load balancing. At that point the statuses of the two machines are reversed, the backup machine becomes active and the primary becomes the standby.
  5. Select an Auto or Manual recovery strategy.
  6. Type an initial heartbeat source address.
  7. Type an initial heartbeat destination address.
  8. Click OK.
