Interesting.  I would sure like some other opinions on that.  The reason for 
going with the NetApp is to use their snapmirror feature in order to copy a 
live database at an instant in time.  Using something like rsync fails 
sometimes because the database could change enough during the sync that it 
can't recover enough to start.

I am copying my NetApp contact (Bcc - he's an escalation engineer and I don't 
want to publish his email address indiscrimately) and I am sure that he would 
also like to talk this over with your contact.  Email me privately if you 
don't want to publish his name either.
