After some EE input and research I'm looking at deploying Volume licenced SBS Prmemium on Vmware Essentials.  What is the recommended disk to use for SBs and the 2008 R2. Is there much performance hit using the thin type of provisoning? MS don't recommend expanding disks on Hyper V Server but is thin provisioning acceptable for an SBS installed in vSphere. The main concern after googling is over provisioning the storage. This is not a concern as it's spinning a 1.2 TB RAID 10 15k SAS so I've plenty of spare as I'll only be proviosning both OS's plus 700 GB fopr the SBS data.

Thick disks are the ONLY disks that are Supported by Microsoft SBS and Exchange installations.

VMware also recommend using eagerzeroed thick disks for applications like Exchange/SBS.

Unless you have storage limitations, there really is no reason to use Thin disks. Some vCenter features (FT, for example) don't work with Thin disks, so just make them 'thick'.
