[CentOS-mirror] New Mirror specs

Hi,

This is surely a FAQ, but I could not find the answer anywhere.

What are the needs in terms of disk space for a CentOS mirror? I understand that we can choose to carry DVD images or not, but can we choose to carry only some archs and/or releases? And in this cases, are there already any measures on disk space needed? Is there some expectancy on how this will increase over time?

I hope to set up a new 1Gbps mirror (inside a 20Gbps backbone) in Brazil ASAP, but first I need to get these and some other answers to convince the bureaucrats. ;-)

Regards,

Jonny
