Enhanced vMotion allows you to combine a vMotion and Storage vMotion into a single operation. Effectivly enabling a “shared nothing” vMotion. Use cases can be found in large datacenters and SMB markets; Cross host and datastore vMotion allows VM migration between clusters in a large datacenters, which may not have a common set of datastores between them.Cross host and datastore vMotion allows simpler setup and use of local disk, by removing the shared storage requirement, it lowers the barrier to entry for use of non-disruptive migrations and will be very useful for the SMB market.
