Doesn't it undup when it goes to tape?
Or am I still living in 5.5 and thinking in VTL dedup?

Subject: [ADSM-L] Deduplication and Collocation

Hello,

I had a student ask me today "What happens if you have collocation
turned on for a storage pool that you are deduplicating?"  I did not
know what to answer because in my mind I thought "well, if the data is
collocated then I need to have a copy of that data on that client's
tape, otherwise I am going to be mounting another client's tape to get
back a de-duped piece of data which would negate the collocation"

I'm looking at the redbooks for this but I only see 6.1 and in 6.2 they
added client side dedup as well (which I also have questions about)

Can anyone shed some light on this?

Thanks!
Mooney
