Abstract
Embodiments of the invention relate to small write performance enhancements for parallel file systems. One embodiment includes flushing a received write transaction from a first memory device to a second memory device on a node in a file system based on one or more byte-ranges within a file system block. It is determined to flush the received write transaction to a recovery log that is stored in a non-volatile storage layer of the file system. If it is determined to flush the received write transaction to the recovery log: appending data associated with the received write transaction in the recovery log of the file system, replicating the data associated with the received write transaction in another non-volatile storage layer of another node if required, and marking the one or more byte-ranges as committed.
