Hi

I have been tasked with find a new moodle server.

We currently run moodle 1.9 with about 3000 users having about 100-200 concurrent users. We use it as our schools VLE and it is used quite a lot with homework, videos and quizzes/surveys being completed on it. 

We have moodle set up on a windows 2008 server, IIS 7 with MySQL and phpmyadmin. 

We are going to be upgrading to moodle 2.4. What specs and setup would people recommend? 

Have people used flash memory? Or sticking with standard HDD? What speed? Setup?

I read that as a general rule you could look at 1GB RAM per 10 concurrent users? How have you found this? 

Thanks
