Thanks for the reply

additional VR servers were added to remote sites because the replication is happening in that country which is thousands of miles away from the primary data centres

I configured the replication using the add-on VR server and it works as expected

We have the embedded primary vSphere replication servers both in the UK and working fine with 60+ replications. The add-on appliances are in a remote country with currently 1 replication configured to use the add on.

my problem is the network traffic being sent to discover all hosts and datastores mappings within that vCenter (not replication traffic, just initial discovery)

support note the logs have: "750+ repetitions for the same host-datastore combination" and have asked me to increase CPU and RAM resources on the add on appliance which I can do but find it hard to believe its the root cause

Anyone seen this before? I am continuing to work with support. We previously had vSphere rep 5.5 setup in the same topology and configuration and had no experience like this

here is an extract of the log analysis (host names have been changed)

---------------------------------------

Searching for the references for specific hosts show 750+ repetitions for the same host-datastore combination:

e.g.

  grep "accessible true" _var_log_vmware_hbrsrv*log | awk '{print $7,$9}'| grep host-87| sort  |uniq -c
