Offloaded Data Transfer (ODX) Support

Offloaded Data Transfer (ODX) is a Microsoft technology based on the T10 COPY Lite specification. The ODX capabilities in Windows Server 2012 and above interact with storage devices to move data through high-speed storage networks.

ODX significantly reduces client-server network traffic and CPU usage during large data transfers, because all of the data movement occurs in the backend storage network.

HPE Storage ODX implementation supports Hyper-V use, and all operations across Windows hosts connecting to the same array. It also supports volumes that are thin-provisioned. When the array's ODX is enabled, standard Copy/Paste, Windows Explorer, PowerShell cmdlets, and XCOPY.EXE should use the ODX copy offload mechanism. ODX tries at least four times to copy before falling back to the standard (non-ODX) copy.
