I will also say this, I manage/maintain several VPLEX arrays (VPLEX Local and Metro) with several Recoverpoint clusters as well.  If you can let me know who your EMC sales person is I can get our sales person to contact yours and setup a reference call with us.  We have an enterprise environment so between me and the other 2 guys on our team (combined 35+ years experience) we can definitely get all of your questions answered.  We have had VPLEX for going on 3 years now so we have seen pretty much everything you would possibly encounter. 
Is there anyone out in the community who would be willing to speak with me about their experience with VPLEX?  I've been asking my local sales team and reseller for a customer reference for a few months, and they're having trouble tracking down anyone who can/will speak to us.
