Question : Exchange 2010 on ESX 4.1 guest best practices

I built out an Exchange 2007 VM a few years ago on ESX 3.5 and it only hosted about 30 mailboxes.  As of now we have about 250 mailboxes.  Since Microsoft seems to enjoy forcing us to build out a new server for each version of Exchange I figure it might as well be done right.

The plan is to run all Exchange 2010 roles within a single guest VM on a vSphere 4.1 host.  The VM will have 2 vCPU's, 8 GB RAM, and Windows 2008 R2 Datacenter.  I plan on attaching a virtual HD as drive D: for the storage groups.

All the info I've found so far is about ESX 3.0 or 3.5 and exchange 2007.  Am I missing something?

Keep in mind that if you are migrating from Exhange 2003/2007 you will need alot more disk space as EX2010 no longer perfors single instance
