I came across this wonderful resource page – Virtualizing Business Critical Enterprise Applications which talks about the successful cases and best practice to deploy the enterprise applications on top of vSphere, such as Exchange, SharePoint, SQL Server, Oracle DB.
This is exactly what I need, as I am currently working on a big scale deployment of some Enterprise applications (Exchange, SharePoint, Lync) in the vShpere environment. I will share more of my personal experiences on this topic afterwards.
