When a VM snap is taken in vSphere, the task is offloaded to the Unity system so a Unity snap is used. The Unity system takes a snaps of all the VVols are the used by that particular VM. The EMC Unity: Virtualization Integration white paper has more information on this.  VVol replication is part of the VASA 3.0 spec. If you need VM-granular replication today, you can use RecoverPoint for VMs.
Hello all,  I am using the UnityVSA to get to know VVols better.  I am familiar with the regular iSCSI-based (block) VMFS Datastores, where I can set up a snapshot schedule, as well as configure replication.  However, I can't seem to find a way to enable snapshot schedules or replication on VVols.  Can someone let me know if this is possible?  I thought one of the main benefits of VVols was the ability to snap and replicate VMs at the hardware-level, granularly, per VM, rather than per-datastore.  But I can't seem to find a way to do this.  Thanks, Bill
