vCloud Connector manages the transfer of content using a separate component, the vCloud Connector node. This flow affects the way a request moves through the system and how network connectivity must be set up.

The following figure shows the path a vCloud Connector request takes in transferring data from a vSphere to a vCloud Director (VCD) cloud.

Note

This figure depicts default settings. Port 443 is used when SSL is enabled and port 80 is used when SSL is disabled. By default, SSL is disabled for the vCloud Connector server and enabled for vCloud Connector nodes.

Enabling or disabling SSL on the vCloud Connector server affects communication from the vCloud Connector UI to the server. Enabling or disabling SSL on vCloud Connector nodes affects communication from the server to the nodes and communication between nodes.

Cross-cloud Data Flow
data transfer
1

Customer requests transfer using vCloud Connector UI.

2

vCloud Connector server tells vCloud Connector node to transfer vApp.

3

Node tells vCenter Server to export using VIM API.

4

Export begins and the following tasks happen in parallel because data is streamed.

Content is moved from datastores to source node cache.

Content is transferred from source to destination node.

Destination node calls the VCD API to import.

Content transfers from destination node cache to VCD transfer server storage.

5

VCD sends the command for the appropriate vCenter import.

6

Content transfers from VCD transfer server storage to destination datastore network and is made available through the VCD catalog.
