"VADP_TRANSPORT_MODE=SAN" means that the data will travel from your esx environment to the proxy through its fiber connection.
To maximize the speed you would need to make your vadp proxy a storage node, zone the proxy to be able to see the drives in the quantum library and add drives to the vadp backup pool that are attached to the proxy. Doing it this way will cause your data to travel like this:
ESX environment ---> VADP proxy (over fiber) ------> Tape drives (over fiber) - of course the metadata will go to the networker server.
If your vadp proxy is not a storage node and you don't have "VADP_TRANSPORT_MODE=SAN" configured your data will go like this:
The NetWorker VMWare Integration Guide page. 18 describes the difference between the different transport modes. Also, later in the document, the 'Planning and Best Practices' gives details on the different considerations for the different modes and performance best practices. Other than this, The NetWorker Performance Optimzation Guide
gives details on tests you can do to identify performance bottlenecks in any environment.
Basically, you need to first be sure that you are following best practices for your environment and then test individual components of the process to see which one is causing the slowness.

Hello,
"VADP_TRANSPORT_MODE=SAN" means that the data will travel from your esx environment to the proxy through its fiber connection.
To maximize the speed you would need to make your vadp proxy a storage node, zone the proxy to be able to see the drives in the quantum library and add drives to the vadp backup pool that are attached to the proxy. Doing it this way will cause your data to travel like this:
ESX environment ---> VADP proxy (over fiber) ------> Tape drives (over fiber) - of course the metadata will go to the networker server.
If your vadp proxy is not a storage node and you don't have "VADP_TRANSPORT_MODE=SAN" configured your data will go like this:
ESX environment ---> VADP proxy (over network) ------> Networker Server -------> Tape drives (over fiber)
You will increase your throughput by having your vadp server be a storage node and assign drives to it.
Hope this helps..
