we plan to launch a big internet project (worldwide learning portal) and we are not sure abou hardware which is usually needed to support such a portal.
At the moment - we need really rough figures to be able to predict our costs per user / ROI etc. We know that reality can be different and this can never be predicted precisely.
Here is some information for you to be able to give us advices:
1) Our server will be visited 24/7 evenly with more/less no peaks.
2) Generally users will be browsing static pages and we count that 1 user will make traffic only about 2MB per hour.
3) Each server will have 100Mbps connectivity to internet.
4) Our (optimistic :) prediction is that there will be about 20 000 concurrent users browsing at one moment.
Is there any configuration of one server that can manage such a number of concurrent users? Or we need more servers?
Could you tell us approximate hardware specification we need for this project?
Thanks a lot in advance,
Tomas
In all seriousnesss though, 1 dual core, dual proc server with 15k scsi drives and 4GB of RAM and take it from there.
FYI, I can run about ~100 pageviews a second with each pageview making 2 db calls on a single proc server with 2GB of ram running ASP.NET and SQL Server.
