Determining the data transfer path
Proxies read data in one of three ways: connecting directly to storage to read blocks, placing the proxy inside the target cluster and attaching virtual disks, or going through the management network. The method chosen determines the load on the production network and the hypervisor.
We first review the customer's storage configuration and assign a transport mode to each job. Datastores that support direct access use direct storage access; for the rest, a proxy is placed in the relevant cluster so no traffic crosses the management network. Communication ports between proxies and repositories are listed in the firewall request before deployment.
