Hey mate, first of all 14 servers for 150 megs seems like you have to many servers, but hey I'm not a tech at all I leave all that stuff to my guys at
www.techiemedia.com I have 7 servers and a load balancer and do approx 500+ megs and the crew there keeps my stuff up and fast for over 4 years now. Do yourself a huge favor and hit up Jim over there before you make a wrong move.
