Method and system for mirrored multidimensional RAID

摘要

The method for storing data. The method includes receiving a write data request, and the memory mode for the data is determined to be mirrored mode, an independent device redundant array (RAID) RAID grid locations in the grid based on the stored mode and writing a data by selecting, and to write data into the memory, and updates the data structure, and to show that the buried RAID grid location, and determine that the data grid is filled including. Based on the determination, to determine the first physical address and the second physical address of the persistent storage during corresponding to RAID grid location, the first physical persistence storage in corresponding to the first physical address writing data to the specific location, writing data to a second physical location of persistent storage during corresponding to the second physical address writing, the persistent storage parity value associated with the data grid.
