SharePoint Capacity Planning Tool - Beta
Be the first kid on your block to try it out. https://connect.microsoft.com/programdetails.aspx?ProgramDetailsID=1602
This handy little tool will allow you to input your number of users, number of locations, bandwidth, preferred hardware, and even usage profiles and then have it spit back a suggested farm topology and suggested hardware. Pretty cool stuff.
A couple of warnings. The tool is still beta so be sure you verify what it is telling you. I have seen some crazy scenarios where you get back the need for 25 servers because you messed up the storage space. J So be smart. Also, you will have to sign up for a Microsoft Connect account. But that is a good thing. Lots of fun betas our there you can apply for.
If you do try the tool out do give your feedback. That is the only way it gets better. Those of us in the real world have to help.
