VTL and Boost protocol (On same fc port?)
Dear DD Experts!
We test some backup environment at the customer. The system has VTL and Boost protocol license.
We want to test both protocols. Before we test both protocols i have some questions:
- If we use VTL and Boost on the same DD it can coexist on same FC port?
- Or VTL and Boost requires an own dedicated port? It can work?
- What is the best practice or recommendations?
Thanks in advance:
Pal

Hi Pal,
I seem to recall the administration guide mentions this, but I could be wrong as I'm going from memory.
However, to answer your specific points:
> - If we use VTL and Boost on the same DD it can coexist on same FC port?
A single host-side FC port may not be used for both DD Boost over FC and VTL traffic to the same Data Domain system.
> - Or VTL and Boost requires an own dedicated port? It can work?
- A single host-side FC port may be used for DD Boost for FC traffic to a Data Domain system A, and for VTL traffic to Data Domain system B.
- A single host-side FC port may be used for DD Boost over FC traffic and for other traffic to non-Data Domain devices.
> - What is the best practice or recommendations?
The current maximum number of devices that can be configured with DD Boost Over FC is 64. This is a device count. The maximum number of stream counts is dependent on the Data Domain System. You can find a knowledge base article describing supported stream counts at the following URL:

The DD Boost administration guide should help provide guidance and recommendations:

Hope that helps.
cheers, Rich.
