To install vCloud Connector for vCloud Air, you need to meet the requirements listed here.


This guide assumes a simple configuration that connects one or more on-premise vSphere instances with vCloud Air. You can also use vCloud Director clouds, on premise or public, with vCloud Connector. For a list of complete system requirements, see System Requirements in Installing and Configuring vCloud Connector. Also note that some features, such as Stretch Deploy (Data Center Extension), have different system requirements.

vSphere 4.0 update 3, 4.1, 5.0, 5.1, or 5.5.x

A Web browser, one of the following:

Internet Explorer 8, 9, 10, 11

Chrome 22, 23

A Windows machine with Internet Explorer

The vCloud Connector user interface appears as a plug-in in vSphere Client. To use the vSphere Client, you need a Windows machine with Internet Explorer.

Downloading vCloud Connector virtual appliances

A vCenter Server administrator account for each on-premise vCenter Server you want to connect to vCloud Connector

User name, password, and IP address

Installing the vCloud Connector node

A vCenter Server administrator account or any account that includes Extension privileges for the vCenter Server in which you want to display the vCloud Connector user interface, if different from above

User name, password, and IP address

User name and password

Registering the vCloud Air vCC node with your on-premise vCloud Connector server

Proxy server

If your on-premise vCloud Connector server or node needs to go through a proxy server to reach vCloud Air, you need to specify proxy server settings during installation. You need the HTTP proxy server name and port number, and, if the proxy server requires authentication, a user name and password.


The user name can only contain lower-case, alpha-numeric characters and cannot exceed 50 characters. Do not use email addresses or domain names (for example, or xyz\user) or names that contain a period as special characters are not supported for this field.


UDT-based data transfer in vCloud Connector is only compatible with SOCKS5-compliant proxy servers, as these proxy servers support the UDP protocol. You cannot use UDT-based data transfer with any other type of proxy server.


vCloud Connector uses the following ports to communicate between its components: server, nodes, and the server and node Admin Web consoles.


Port Number



Used when SSL is enabled.

This port is used for communication between the vCloud Connector server and vCloud Connector nodes and between nodes.

By default, SSL is enabled on nodes.


Used when SSL is disabled.

This port is used for communication between the vCloud Connector server and vCloud Connector nodes and between nodes.


Required on the destination node for UDT-based data transfer.


When you copy data between your on-premise environment and a public cloud, port 8190 needs to be open on the public cloud.


This port is used to access the vCloud connector server and node Admin Web consoles using a browser.

For each cloud (on-premise vSphere or vCloud Director instance, or vCloud Air) that you add to vCloud Connector, the vCloud Connector server must be able to reach the following.

The vCloud Connector node associated with the cloud

The cloud

The vCloud Connector server accesses the cloud directly to get its inventory and for tasks such as powering on or powering off virtual machines. It accesses the cloud through its public REST API endpoint.

If there is a load balancer between a vCloud Connector node and the cloud with which it is associated, the load balancer should have session persistence enabled.
