Windows Server offloaded data transfers (ODX)
Offloaded data transfers (ODX) support was added in release 3.0.53 of the storage virtualization software. As with VAAI, offloaded data transfers enables high speed copy operations by offloading the entire copy operation to the array. This feature is beneficial for virtual machine (VM) clone operations, significantly reducing host CPU and network utilization. Users of ESXi will notice the similarities with VAAI third party / full copy primitive.
