Why Have VVOLs Taken So Long to Deliver?

Chris Evans of Architecting IT comments:

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. Although we’ve seen demonstrations of VVOLs  for some time, VVOL code has not yet made it into a GA vSphere launch.  Presumably this will change with the release of vSphere 6.0 sometime next year.  The challenges around what seems like a trivial change in storage deployment are pretty immense and require work from both the hypervisor and storage side.
