2 years back when I was working on SharePoint 2007 , virtualization of SQL Server was not recommend due to performance and clustering issues. When it comes to SharePoint 2010 , I see most of the MVPs support SQL Server Virtualization. I could catch up with the latest advancements of the virtulazation so I would like to know the your opinion and also answers for following queries.
Are the performance and clustering issues resolved (I/O speed..etc) , If yes, what special instructions do we have to follow ( dedicated H/W , I/O benchmarks.. etc)
Known Issues when we go this option
This farm is decidated to host Internet sites with user base around 100K (anonymous mostly) , So do we have any special considerations to follow?
Any size of feedback is appreciated, thanks
