Our experience in virtualization

I work in Intel IT. We have been studying the benefits of virtualizatoin and have start deploying it at a larger scale since last year. We were planning for a 10:1 to 16:1 consolidation ratio. I believe we are targeting 14:1 to 20:1. My colleague has documented our experience and lesson learnt in a white paper. It is an interesting read.
