Anyone got a 4-way exchange 2000 cluster? I'm looking at 2, to support worst case, 15,000 users each. 3 active/1 passive, 3 Virtual servers per cluster, therefore 5000 users per VS. 100Mb mailbox limits. Is this realistic thinking? Am also considering putting in some front end servers at some of our less well connected sites, and also using them for Instant Messenger servers. Any thoughts?
