Another VMworld has come and gone and still we haven’t seen the production deployment of VVOLs. Just to recap, VVOLs are the evolution of the packaging of virtual machines that currently reside in data stores. The main benefit is to be able to apply storage performance and availability policies to a VM object rather than an entire datastore as we do today.
