My organization is moving to Exchange 2007 from 2000. Our new server is a Dell Poweredge with 8GB of RAM. It currently has about 50 mailboxes on it and will ultimately have about 90. Of those, only about 50 are user mailboxes. The rest are resources and shared mailboxes.
My store.exe process is using almost 6GB or RAM, even after a recent reboot!! I only have about 655MB free and I have only moved about half my mailboxes over. According to the system requirements I should be able to get away with 2.5GB so I figured 8 would be much more than enough.
The next most memory hungry process is for our Sunbelt Ninja Anti-Virus/Anti-SPAM software which uses about 350MB of RAM. The swap file is set to a minimum of 4GB and max 8GB. Should I up that to 8-12GB?
Do I need to upgrade to 16GB RAM? Is there some tuning or setting changes I should make?
