Hello 'colleagues', we are about to expand our current environment because of the coming of 22.000 mailbox-users. At the moment we serve a little less than 8.000 users on two 2007 SCC mailbox-clusters with two nodes each. We're about to purchase another six mailbox-clusters (with 4.000 mailboxes per cluster in mind), but we're not sure about the number of cla's, hubs and edges. At the moment we have two of each. Does anyone have a recommendation about this, or some hyperlink to an article about this. I'can't seem to find anything, but I guess I'm not using the right keywords :-( Thanks in advance!

I recommend that you hire a consultant. You can't expect a good answer to a question like that for free in what is basically a short-answer forum. If you get an answer, consider it to be worth what you're paying for it. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .
