I have been assigned the task of planning and designing a new midsize network for my firm. The network will consist of 60 users, Microsoft Exchange, Microsoft SQL, Remote Access and VOIP for phones.
I'm not sure on the approach I should take, I was thinking something along these lines:
One server for AD
One server for Exchange
One server for MSSQL
One server for File Server
Is it feasible to save on getting the fourth server by combining the file server and AD server roles to a single server?
I'm not very familiar with virtualization, should I be considering it as a better alternative?
