A method, apparatus, and system for implementing a multi-level redundant array of independent disks (RAID) architecture to increase data storage system performance and/or redundancy of data. In one embodiment, the RAID architecture includes, at the lowest or n-th layer, a plurality of nodes or storage devices implementing striped, mirrored, and/or other RAID algorithm, and assigned a system identification or LUN (logical unit number). Each LUN is part of a larger data storage system that may employ one or more other RAID organizations such as a RAID 4 or RAID 5.
