Abstract: Processing data in a distributed data storage system generates a sparse check matrix correlating data elements to data syndromes. The system receives notification of a failed node in the distributed data storage system, accesses the sparse check matrix, and determines from the sparse check matrix a correlation between a data element and a syndrome. The system processes a logical operation on the data element and the syndrome and recovers the failed node.

Abstract: During runtime of a system, a memory controller is caused to relinquish control of a memory module that includes a volatile memory and a non-volatile memory. After the triggering, an indication is activated to the memory module, the indication causing a backup operation in the memory module, the backup operation being controlled by an internal controller in the memory module, and the backup operation involving a transfer of data from the volatile memory to the non-volatile memory in the memory module.
