Among redundant arrays of independent disks（RAID）-6 codes, maximum distance separable（MDS）based RAID-6 codes are popular because they have the optimal storage efficiency. Although vertical MDS codes exhibit better load balancing compared to horizontal MDS codes in partial stripes, an I/O unbalancing problem still exists in some vertical codes. To address this issue, we propose a novel efficient data layout, uniform P-code（UPC）, to support highly balanced I/Os among P-coded disk arrays（i.e., PC）....
