First, please excuse me for my poor english ... I'm french and can better write in spanish than in english.
I'm the manager of a technical service for e-learning in our university (Toulouse, south of France ... famous city for Space Research and Aeronautic Industry), and pilot for the french e-learning university of law.
We are actually migrating from WebCT 4.1 to Moodle 1.4.4. At the beginning, we were testing on a Bi-Pentium III 933, with 640Mb RAM, and 54 Gb HardDisk. We started the first act of the migration on this server.
But this server must be able to receipt courses for 17.000 students of our Toulouse's university next year. And, for the french university of law project, we must buy another server for both Moodle (with MySql bases) and a CMS. So we are looking actually to buy 2 new servers, 1 dedicated to moodle (17.000 students) and another for Moodle and the CMS (approximatively same number of students).
Can someone help ourselves for technical datas, or give us links to better appreciate minimum and optimum configurations. Must we separate database server and application one's.
Thanks for your answers
