HI There, I am working with a new customer on designing an Exchange 2010 that is highly available. I am trying to design the correct number of servers.
What i was thinking is having 4 servers with the following setup.
2 x Mailbox servers with DAG
2 x Servers with HT and CAS and load balance these in some method
Is it possible to have just 2 servers with all the above roles.
We will be using external mail filtering for spam and filtering.
Any advise and suggestions would be greatly appreciated.
