just about to start a new install of Exchange 2013 (on server 12r2) to replace our Mdaemon server.
I have bought a Dell T630 with 6 physical drives
2 for the os on a raid1, leaving me 4 drives for exchange.
The servers role is purely exchange with both mailbox & client access an nothing else
I have tried to find best policies for hard drive configs but nothing is obvious.
