Abstract: Intra-block error correction including generating reconstructed sub-portions of a portion of a dataset that is distributed into a plurality of portions that are stored on different storage devices of the storage system, wherein the dataset indicates a first number of errors that is greater than a second number of parity data portions of the dataset, determining that a sub-portion of the dataset does not match a corresponding reconstructed sub-portion of the dataset; and based on the determination, replacing the sub-portion of the dataset with the reconstructed sub-portion of the dataset.

Abstract: A method of operating a storage unit having non-volatile random-access memory (NVRAM) and solid-state memory is provided. The method includes transferring contents of the NVRAM to the solid-state memory, in response to detecting a power loss. The method includes during the transferring, having each of a plurality of channels in parallel, reading one or more of a plurality of logical unit numbers (LUNs) each corresponding to a portion of the NVRAM, performing an XOR of data of each of the one or more of the plurality of LUNs with data of a preceding LUN, and writing results of the XOR to the solid-state memory.

Abstract: A method for processing blocks of flash memory to decrease raw bit errors from the flash memory is provided. The method includes identifying one or more blocks of the flash memory for a refresh operation and writing information regarding the identified blocks, to a data structure. The method includes issuing background reads to the identified blocks, according to the data structure, as the refresh operation. The method may be embodied on a computer readable medium. In some embodiments the background reads may be based on a time based refresh responsive to an increase in raw bit error count in the flash memory over time.

Abstract: Reading data stored at a free block of a storage device is read prior to allocating the free block for storage of data. A determination as to whether a number of bit flips of the data stored at the free block is below a threshold is made. The free block is added to a pool of active free blocks to be allocated for the storage of data upon determining that the number of bit flips of the data stored at the free block is below the threshold.
