Ben,
First, thanks for sharing your experiences.  Very enlightening.

I'm curious why you decided to use devclass=file volumes, instead of using
the DD580 as a VTL.  It does have a VTL personality, doesn't it?

TSM config - Easy. Created some "FILE" device classes and pointed them
to the NFS mount points.

You also did some analysis about what type of data got what level of
reduction.  How did you go about testing this?  Do you use separate storage
pools to segregate the data and then run a test?  I don't see any other way
to do it.

Thanks.
