摘要：Storage servers use a fast, non-volatile or persistent memory to store data untilit can be written to slower mass storage devices such as disk drives. If the server crashesbefore a write can complete, the data remains safely stored in non-volatile memory. Ifthe data cannot be committed to disk when the server reboots (e.g. because the

destination mass storage device is unavailable), it is stored in a file. When the diskreappears, the data in the file may be used to restore a file or filesystem on the disk to aconsistent state.
