NBU workig with Data Domain on AIX 7.1

Hello everyone.

We have a Data Domain, model 4500 and we try to use DD Boost for Symantec NBU. But in this moment the configuration on the media servers has an issue. This is the problem:

Our  media server send the data over the LAN, this is because each server can't use the FC, we like to know if exist any restriction when NBU use a media server with OS on aix 7.1. The data in this moment is send over administration interface, 1 GBps, this is very slow.

We don't have 10 gigabit ethernet.

I really appreciate any information, recommentation or help to solve this issue.

I have a doubt, can I configure a SAN Client and send the data over FC? This client could be on any version of OS?

We use:

NBU 7.6.0.2 on the master and media server.
