Vcloud Conector Appliance Considerations:
*The Virtual Appliance must be deployed to a Vcenter server and available Vcenter Server clients. User access is via Vsphere client -via Vclould Connector must have right log into Vcenter server.
*Workload copy operation user the Vcloud connector appliance as middleware so network latency and bandwidth between clouds need to be put in an account. Most cases it may be preferred to run on multiple instance of Vcloud Connector across multiple Vcenter Server instances to avoid network latency or consuming excessive bandwidth.
