To get application consistent copies of your data you need something else as well¿ Replication Manager. RM would be your GUI based scheduler & VSS requestor to quiese the Exchange. Otherwise you would manually have bring it down unless you are happy with crash consistent copies of data¿But as we all know Exchange is notorious for getting easily corrupted and MS does recommend that you check any replicas with ESEUTIL. Talking about replicas clones are the only correct choice for Exchange!
I hope and assume that the physical LUN layout has been done correctly and that you already aligned the LUNS in the OS too. Do a search on Powerlink for EMC Clariion and Microsoft Exchange 2007 and you will be spoilt for choice for white papers. Likewise loads of stuff available for RM too.

I hope this helps?

Using RM makes life easier, but it is not mandatory. You can use consistency groups, but you can also bring down Exch every evening or so to have the needed consistency of the db's. Take a snapshot at that point and kick Exch into geear again.

Maybe this could help you. I wrote this with that purpose:
