Server Requirements in Admin Guide

Hi All,

Not sure if anyone knows this, I have a customer asking about a new server set up for their CRM and I've tried to find in the Admin guide for CRM anything about how servers should be set up - when you can get away with one server or when to split it over two. etc.

Also I vaguely remember it used to say for the SQL server you need to have 1Gb RAM for 1Gb of the CRM database, but I can't find it anywhere in order to provide to the customer.
