RAID WRITE REQUEST HANDLING WITHOUT PRIOR STORAGE TO JOURNALING DRIVE

摘要

An apparatus may include a storage driver, the storage driver coupled to a processor, to a non-volatile random access memory (NVRAM), and to a redundant array of independent disks (RAID), the storage driver to: receive a memory write request from the processor for data stored in the NVRAM; calculate parity data from the data and store the parity data in the NVRAM; and write the data and the parity data to the RAID without prior storage of the data and the parity data to a journaling drive. In embodiments, the storage driver may be integrated with the RAID. In embodiments, the storage driver may write the data and the parity data to the RAID by direct memory access (DMA) of the NVRAM.
