A couple of months ago VMware released some whitepapers about running Exchange 2010 and MS SQL Server on VMware vSphere.
The VMware communities site has a spot called VIOPS where you can see posts from members in the community about recently posted documents. There are some nice documents available about virtualizing Exchange 2010 and SQL server 2008 on vSphere 4.1.
There are a couple on Exchange and a couple on SQL Server, for each product a “best practices document” and an “availability and recovery options” document.
On the bottom I added some other links related to virtualization of SQL and Exchange.
On the following link you can find the four documents all together:

Microsoft’s reaction on running Exchange Server 2010 on VMware vSphere
DELL has some whitepapers available about Exchange 2010 on vSphere with Equalogic storage underneath:
HP published a whitepaper about Exchange 2010 and storage, not directly a focus on virtualization, but it shows the evolution in IOPs needed comparing different versions of Exchange (2003/2007/2010). It shows 2010 really is less demanding on the IOPs side. Although it’s about HP storage you can filter out the info that applies to other storage vendors.
