Abstract
Method and apparatus for managing data in a data storage system. A storage array controller device is coupled to a plurality of storage devices by an external data path, with the storage devices used for non-volatile memory (NVM) storage of user data from a host. A copy back operation is initiated by issuing a copy back transfer command that identifies a selected data set stored in a source device and a unique identifier (ID) value that identifies a destination device. A peer-to-peer connection is established over the external data path in response to the copy back transfer command so that the selected data set is transferred from the source device to the destination device while bypassing the storage array controller device. Normal data transfers can be carried out between the storage array controller and the respective source and destination devices during the copy back operation.
