Actually I have more customers using Data Domains without the VTL license than 
with it.

With a Windows TSM server, you can just write to it via TCP/IP using a CIFS 
share(NFS mount with an AIX TSM server).
If you have sufficient TCP/IP bandwidth for your load, no fibre connections 
needed.
>From the TSM point of view, you configure it as a file pool.

You get the benefits of dedup and (if you have a 2nd one at your DR site) 
replication.  
Neither good or bad, just different.
Very simple setup, works great if it meets your throughput requirements.

The fact you actually need to pay a "VTL license" is just plain scary.

When u bought it, did they think you're gonna use it as a fileserver? I'm not 
to specialized into Data Domain, but arent they marketed as backup hardware? So 
you get a disk, but if you want to use it for something else than that, you 
need to pay a license?

Sorry for sounding bitter, but I've always heard people referring to Data 
Domain as a VTL.

Not supported by what?

If you've got a DD, then the simplest way to connect it to TSM is via files.  
Some backup apps require something that looks like a library, in which case 
you'd be buying the VTL license.

FWIW, if you're already in DD space, you're paying a pretty penny.  The VTL 
license isn't chicken feed, I agree, but it's not a major component of the 
total cost.
