I am trying to decide on the server requirements for a new DotNetNuke installation. I have will about 25 websites running off this installation on this server.

My decision comes down to this. What's more import for DotNetNuke: CPU power, amount of memory (RAM), or disk IO, and in what order?

Below are the two options I have for dedicated servers. Based on your experience with DotNetNuke, which is the best one for me to get?

Server 1 Config (more CPU power but slower hard drives and less RAM than option 2):
Dual Opteron 2212 Dual Core Processor (4 processors total)
2x HDD: 250GB Hard Drive SATA
RAM: 2048 MB RAM

Server 2 Config (less CPU power but faster hard drives and double the RAM):
Intel Xeon 3060 Dual Core Conroe Processor (2 processors total)
2x HDD: 146GB, 10K RPM SCSI/SAS Hard Drive
RAM: 4096 MB RAM

Thanks for any assistance!

Carol,

Either would work fine. We are running about a half million user sessions a day across about 30 sites on a single server (3 DNN the rest a mix of ASP and .Net) with a dual core P4 and 4 gigs of Ram.  The only time the server even flinches is when an app is loading the first time but once it's precompiled it runs smooth hovering at around 15% utilization). If you are after a performance bump you may want to consider 2 lower powered machines and host SQL Server on it's own box.
