What is best solution for exchange 2010 redundancy DAG or NeverFail
we currently have an exchange server 2010 sp3 with around 1500 users on it.
this server is virtual
we need to setup some sort of redundancy for our email system
We are currently looking into either setting up a DAG or maybe using Neverfail
Has anyone any thoughts on which is better
if i have 7 databases on our mail server at the minute do i need to buy enterprise exchange for the second exchange DAG member?

then id server 1 goes offline server 2 databases become active
