Abstract
Writing to a storage system with data striping includes storing blocks of data in local memory until one or more full-stripe write operations can be performed, thus reducing write amplification on the data striped storage system. Crash recovery information includes storing the data associated metadata to respective persistent storage devices. Metadata associated with data from several clients is combined into fixed-size data blocks and stored on the respective persistent storage device.
