Hi I need some guidance on the hardware specification of a Hyper-v hosted web server. I need to host a website totalling about 25mb with a maximum of 100 concurrent connections. My questions is, what OS should I use, how much RAM do I need and what processor options should I go for? Surely there is a calculation I can use to find this information rather than over speccing the server just to be safe. My assumption is 4GB of RAM would be suffice, but I need to confirm this along with CPU core requirements? Any help would be greatly appreciated.

Thanks Martin, The site is coded in php and does not use a DB. Would Windows Server 2008 R2 be a sensible choice?

Hi, Windows Server 2008 R2 is your choice.
