Simplified RAID for Byte-Addressable Memory via Media Controllers

The patent segments the RAID implementation into independent media controller units, each capable of autonomous RAID operations. By dividing the system into multiple independent controllers that can operate in parallel, the patent reduces transaction-processing time while maintaining data redundancy through distributed RAID group management across the segmented controllers.

The patent implements preliminary action by pre-calculating and storing RAID group mapping information in lookup tables within each media controller. This allows controllers to quickly determine stripe assignments and parity calculations without complex real-time computations, thereby reducing transaction-processing time while preserving reliability through pre-established redundancy schemes.

The patent extracts the complex RAID logic from the byte-addressable memory devices and relocates it to dedicated media controllers. Each media controller contains simplified logic for managing RAID groups, while the memory devices themselves remain simple storage units. This extraction reduces hardware logic complexity at the memory device level while maintaining data redundancy through the distributed controller architecture.

The patent introduces media controllers as intermediary components between the host system and byte-addressable memory devices. These controllers handle all complex RAID operations including parity calculation, stripe management, and redundancy maintenance, thereby reducing the hardware logic complexity required in the memory devices themselves while preserving full RAID functionality through the intermediary controllers.
