VVOL support?
Nothing like a paid report to get a good review :)
Anyhow, it certainly seems to address many management issues that VMware has today but as VMware will be introducing Virtual Volumes (VVOLs) which is designed to abstract provisioning, replication, snapshot etc to make it easier for VMware to manage the storage, I dont really see how well this will play in the future.
