NVRAM ENABLED STORAGE SYSTEMS

摘要

A method of preventing data loss is disclosed that includes writing data first to a NVRAM device, then to a storage device with volatile memory and persistent medium, and checking whether data is on the persistent medium before deleting the data from the NVRAM. A method of reducing read-modify-writes and write amplification is also disclosed that includes writing data first to a NVRAM device, accumulating data in full stripes before writing the data to a RAID system in full stripes and to each storage device in contiguous chunks sequentially.
