Maximum processor and memory configuration for Exchange

Hi,

Just to share, do you know that Exchange only be able to adopt a maximum of processor and memory? No point you put it to the max.

For Exchange 2003
Gateway or Bridghead can support up to 2 dual-core with 2GB ram
Front End Server can support up to 2 dual-core with 2GB ram
Mailbox Server can support up to 4 dual-core with 4GB ram

For Exchange 2007
Edge Transport/Hub Transport can support up to 2 dual-core with 8GB ram
CAS or UM Server can support up to 2 dual-core with 8GB ram
Mailbox Server can support up to 4 dual-core with 32GB ram

P/S please take note that MSFT do not recommend to host more than 4000 mailboxes in a server, regardless of Exchange 2003 or Exchange 2007

This is the power of 64 bit, peers...
