    ePO Full Replication to SADR Failure w/ High Latency

    chris77

      Hello,

       

      I am currently testing the effects of worst-case latency and throughput on the ePO to SADR Full Replication task.

       

      My topology includes: ePO+DB---vSwitch---NetworkImpairmentTool---vSwitch---SADR

       

      I have manually set the throughput between ePO and SADR to 1 Mbps and the latency to those listed below:

       

       

      Tested Latency (one-way)Ping RTTDurationSuccess?
      0 ms~2 ms3h 27mYes
      150 ms~302 ms5h 54mYes
      300 ms~602 ms9h 05mYes
      325 ms~652 ms2h 17mFails @ 30%
      350 ms~702 ms3h 31mFails @ 30%
      410 ms~822 ms4h 03mFails @ 30%
      450 ms~902 ms4h 25mFails @ 30%

       

      So here are my questions:

       

      1.) What is the reason, from an application standpoint, that this failure would occur at latencies over 300 ms?

      2.) What can I do to make the ePO more tolerant of high latency and low throughput?

       

      Regards,
