Exchange 2007 has more granular divisions. Dividing Exchange features among several server roles has advantages. More flexible deployment topology. For a small or medium company that has only hundreds of mailboxes and all users are centralized, customer can install all necessary roles on one substantial server. For a big enterprise where tens of thousands of mailboxes span numerous physical locations, customer can select to arrange each role on a separate server or even multiple servers per role to supply superior performance and fault tolerance. Better hardware utilization and scalability. Each role only installs binaries and runs services for a definite quality set. Contrasting older versions of Exchange, configuring a server that has only one or two roles will lessen Memory, CPU and disk space requirements for this server. Easy to maintain. Upgrading, applying hotfix, or other server changes that could cause server outage can be secluded to one server role. This reduces protection down time and end user impact.
