Yes I do but I can not share the names with people outside of my company,
sorry.
I'll tell you it's a mid sized company with two Protectiers in two
locations that replicate, the customer has the entry level TB license model
and IBM used the protectier interface to determin the dedup savings for the
license if I am not mistaken.
It could very well be what Nick wrote but I would tell your IBM rep that
you have read about several cases and request them to ask again.
