Idea how to improve Replication performances between VSphere vCenter 7.0.1 and vSphere Replication 8.3 using different Networks

Hi,

I need a Help to improve performances replication procedure.

 

This is scenario of my infrastructure:

two ESXi 7.0.1 with 2 NIC 1Gb 2 NIC 10Gb

Two NAS Storage with 2 NIC 1Gb, 2 NIC 10Gb

Two Switch with 8 port 1 Gb, 4 port 10Gb

 

My idea was to have:

1Gb network for Management and VM network

10Gb network for Vmotion, Storage and Replication

I have connected, all devices, one port 1Gb to Switch A and other 1Gb port to switch B, the same has been done for port 10Gb to create ridondances.

 

vSphere Server is connected to 1 Gb Networks.

 

With this configuration the Replication working but I have poor performances.

 

I have verified that we have a bottleneck with the Gateway because all traffic pass from network 1 Gb to network 10 Gb Utilized for write.

 

I have verified that vSphere Server can have a second NIC but it’s only for HA and doesn’t works as management and I can't use this to connect Replication Server to vSphere Server on the 10Gb networks.

 

The question is: to have good replications performances is I need to move all the management networks on 10Gb Networks or There are other configuration can I apply and I can  keep the management on 1Gb Networks?

Thanks for your support

Attached
