In VMware Cloud Director Availability, you can set a global limit for the total incoming replication traffic from all remote cloud and on-premises sites. You can also configure a limit for the replication data traffic from on-premises sites to the cloud site. Throttling the network bandwidth can prevent the network saturation and avoid overloading of the management connections with replication data traffic sharing the network infrastructure.

In VMware Cloud Director Availability, throttling the network bandwidth to the specified megabits per second limits only the replication data traffic transfer rate. The bandwidth throttling does not limit the transfer rate of other types of network traffic like data and the management traffic.

Global Bandwidth Throttling for the Cloud Site

The global bandwidth throttling limits the transfer rate of the combined incoming replication data traffic to all local Cloud Replicator Appliance instances from all remote cloud or on-premises sites. This global traffic limit operates with any number of Cloud Replicator Appliance instances. The number of data connections or the activity within the connections has no effect on the bandwidth throttling.

On-Premises Bandwidth Throttling to the Cloud Site

The outbound network bandwidth throttling from on-premises sites to the cloud site applies to each individual VMware Cloud Director Availability On-Premises Appliance instance.

Configuring replication policies with an outbound bandwidth throttling limit for the traffic from on-premises appliances to the cloud site does not affect the traffic from a cloud site to a cloud site, nor affects the traffic from the cloud site to the VMware Cloud Director Availability On-Premises Appliance.

Configuring the organization replication policy with bandwidth throttling limit affects the transfer rate from all VMware Cloud Director Availability On-Premises Appliance instances, on all on-premises sites that target the respective organization.
