Abstract
Example storage systems, storage devices, and methods provide secure transfer of data between peer storage devices using protection information. Data operation commands may be received that use a protection information data block format for transferring a target data block between peer storage devices. A local data operation may operate on the target data block in a first storage device and compare at least one protection information tag value to a first data check value. At least one destination verification protection information tag value and the target data block may be transferred to a second storage device through a peer communication channel. The destination verification protection information tag value may be compared to a destination data block protection information tag value by the second storage device. The second storage device may then execute a data operation on the target data block. Protection information tag values may include guard tag values, reference tag values, and application tag values managed by the peer storage devices.
