"All storage used by an Exchange guest machine for storage of Exchange data must be block-level storage because Exchange 2010 doesn't support the use of network attached storage (NAS) volumes. Also, NAS storage that's presented to the guest as block-level storage via the hypervisor isn't supported."
Is anybody running Exchange 2010 using NFS for storage of database and logs files?
I did find one person who is running Exchange 2010 under vSphere using NFS datastores for the Exchange database and log files and having no problems. We are currently using SME for our Exchange 2007 server but will not be using it for Exchange 2010. I will be using Commvault instead of SME. SMSQL, and SMVI so I get one spot where all of my backups occur.
