  Hello everybody,
  
  I want to know the hardware requirements for installing an exchange server 2007 unified messaging for about 100-150 users.
  
  I read the minimum hardware requirements presented by Microsoft, but of course these are the "minimum" requirements and not the recommended ones.
  
  SO i wonder if a quad-core AMD Opteron processor with 2*2 GB of memory and Raid 5 hard disk, each with 1 TB of space is really required or is it too much ?
  
  Maybe we can reduce the 1 TB space for each mirror hard disk in the Raid 5 to let's say 250 GB each...will it still be feasible and recommended since the hard disks are the most expensive parts in the server?
  
  Thanks a lot
  
  Elliot
