In VMware Cloud Director Availability, as a service provider, you can set a global limit for the total incoming replication traffic from all remote cloud or on-premises sites. You can also configure a limit for the replication data traffic from the on-premises to cloud sites. Throttling the network bandwidth avoids the network saturation and prevents the overloading of the management connections with the replication data traffic that shares the network infrastructure.
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 transfer rate is measured in megabits per second.
Throttling the global network bandwidth only applies to the inbound replication data traffic without affecting other types of network traffic like data and management. The 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 Outbound Bandwidth Throttling
The on-premises outbound bandwidth throttling applies per an individual VMware Cloud Director Availability On-Premises Appliance.
Configuring the organization replication policies with an outbound bandwidth throttling limit for the traffic from on-premises appliances to the cloud site is in megabits per second. This limit applies only to the replication data traffic from a VMware Cloud Director Availability On-Premises Appliance to a cloud site. This limit does not affect the management traffic and the replication data traffic from a cloud site to a cloud site and from a cloud site to a VMware Cloud Director Availability On-Premises Appliance.
Configuring a replication policy with a bandwidth throttling limit affects all VMware Cloud Director Availability On-Premises Appliance instances, on all on-premises sites that target the respective organization. Each VMware Cloud Director Availability On-Premises Appliance 4.0 receives and enforces the limit. Older versions of the appliance do not receive the limit.
