Various implementations described herein relate to systems and methods for a storage device (e.g., a Solid State Drive (SSD)) to perform a Compute Function (CF). One or more embodiments include a method by which a data transfer is annotated to call out a computation to be performed by the storage device on data before, after, or in parallel with reading the data from or writing the data to the storage device. One or more embodiments include a storage device including a controller, wherein the controller is configured to perform a method including receiving a command from a host, the command identifying the CF, and in response to receiving the command, performing the CF on at least one of internal data stored in the storage device or external data transferred from the host to determine the computation result of the CF.

Data exchange between host and storage device using compute functions

Various implementations described herein relate to systems and methods for transferring data from a source device to a destination device including receiving, by the destination device, a copy request from a host, performing, by the destination device, transfer with the source device to transfer data from buffers of the source device to buffers of the destination device, and writing, by the destination device, the data to a non-volatile storage of the destination device.

Systems and methods for data copy offload for storage devices

Various implementations described herein relate to systems and methods for providing data protection and recovery for drive failures, including receiving, by a storage device, a write request from a host operatively coupled to a storage device, and determining, by the storage device instead of the host, an XOR result by performing an XOR operation of new data and existing data. The new data is received from the host. The existing data is stored in the non-volatile storage.
