vSphere Replication Appliance, Communicating to Remote ESXi Hosts Port 80??

I have a very odd issue.

Our setup looks as follows

VC01 (vCenter Managing)

          Datacenter A (Primary - South Datacenter)

               ESXICLUSTER01

                    vSphere Replication Appliance 01 (VM)

          Datacenter B

               ESXICLUSTER02

         Datacenter C

               INDIVIDUAL REMOTE STAND ALONE  HOSTS (40+)

DRVC01 (vCenter Managing)

          Datacenter D (Secondary - North Datacenter)

               ESXICLUSTER02

                    vSphere Replication Appliance 02(VM)

Basically, in short, we have replication setup on 20 VMs ONLY between Datacenter A and Datacenter D.

HOWEVER, we're seeing a ton of traffic from the vSphere Replication Appliance in Datacenter A and the Stand along remote ESXi hosts in Datacenter C. All of this traffic is on Port 80, and it's bi-directional. The ESXi remote hosts are communicating to the replicaiton appliance, and vice versa. However, NOTHING is being protected at the Datacenter C remote locations. Why is the vSphere replication appliance being so chatty with the management network of remote ESXi hosts which it is not protecting? This is saturating our remote location circuits with hundreds of thousands of transmits.

Hi,

In all VR releases VRMS adds all hosts in the vCenter server inventory to all VR servers - for potential usage of accessing target datastores. There is no feature to limit to specific clusters.

Each VR server connects to the different hosts and lists available datastores.

To investigate the network saturation due to this listing of available datastores, you might want to look at VR server logs at /var/log/vmware/hbrsrv* and perhaps open a SR to have the VMware support team assist.

Regards,

Martin
