Virtual Geek has a some great performance and power consumption numbers up on his blog for virtualizing Microsoft Sharepoint. I've gotten lots of questions over the past year or so about how SharePoint would perform in a VM and this is the best data that I have seen to answer those questions. He has info about how you can download the full report from EMC's Powerlink site, but the charts and info in his blog post seem to cover the main points. The amount of savings in terms of power are so big as to be unbelievable, but after looking at the details behind them it all seems to add up. An excellent read - I recommend that you check it out.
