I am setting up a website on win2008/sql2008 (64 bit) on a dedicated server, which may get 50K to 100K users/visitors. Concurrent users at any time may be 1000 (max). Users will log in 4 to 6 times a month and spend 10 minutes (maximum) on the site for minimal data entry. There will be some reporting run at night. The site has no image transfer facilities, except for one member photo.
I am wondering if any of the following specs will be enough for the server.
1) Core i7-860- 8GB RAM, 1.5TB bandwidth
2) 2x 5420 - 8GB RAM - 5TB bandwidth.
How do I calculate bandwidth and server capacity utilization? Am I getting a much bigger box than needed with # 2. The data entered by users is minimum. Users choose 10 to 15 drop down fields, type in a few numbers and click sybmit..
I am planning to get 100 MBPS port speed. Do I really need that much or will 10 MBPS be enough?
