Abstract:
One embodiment provides a storage system. The storage system includes storage system control logic to identify at least one target storage device in response to detection of a failed storage device, request a state of a target device logical block address (LBA) from each of the at least one target storage device, and read data associated with a mapped device LBA from each target storage device and write the data to at least one replacement storage device. Another embodiment provides a storage device. The storage device includes device control logic to determine a state of a target device logical block address (LBA) in response to a request; a host interface to provide a reply to the request, the reply including a state indicator related to the state of the target device LBA; a map table including a plurality of device LBAs and respective state indicators; and non-volatile memory (NVM) including data related to at least one mapped LBA.
