ODX (Offloaded Data Transfer)

Definition

ODX (Offloaded Data Transfer)

Offloaded Data Transfer (ODX) is a feature in Microsoft Windows Server 2012 that speeds up 'copy and move' operations.

Standard copy operations are achieved by reading the data onto the server, buffering it, and writing it to another storage volume. ODX speeds this process by offloading the entire orchestration to storage and using tokenization for reads and writes without buffering. This can ultimately cut down on CPU cycles.

ODX is only available with compatible hardware. To take advantage of it, a virtual machine must be connected to the storage as a SCSI device. However, functionality is enabled automatically as long as the hardware is compatible.
