When should I purchase server ?Per Processor licences?
When you are an external user accessing a server or when you count the CALs required and the total cost is more than the cost of per processor licensing option. This is called break-even point. For example, say you have 120 staff and student computers accessing your server with four processors. You can pay $80 a user or $7,000 per processor (the figures for illustration only). Per user would cost $9,600, while per processor would cost $28,000, making the former option more cost effective.
