    FoE and APE Scenaro across WAN question

    steverunner

      Can anyone help me understand how FoE would perform in the following scenario?

       

      We have our main polling engine in our UK data center, and an additional polling engine (APE) in the United States.

       

      We plan in installing FoE so that the UK server is the active primary, and the APE in the US is the passive failover system.

       

      Question: What happens when the US to UK WAN link is down?

       

      (A) if the main polling engine is functional, will it continue to poll nodes on it's side of the WAN link?

      (B) if the WAN link does down, and THEN the main polling engine crashes...how will the passive failover know to take over?

       

      Thanks for your help/advice on this.
