A computing system is operable to generate a plurality of lines of coding blocks that includes a plurality of data blocks and a plurality of parity blocks. Each of the plurality of lines of coding blocks includes a corresponding subset of data blocks a corresponding subset of parity blocks. A set of segments of a segment group are generated to collectively include the plurality of lines of coding blocks. Different coding blocks of each of the plurality of lines of coding blocks are included within different ones of the set of segments, and the plurality of parity blocks are dispersed across all of the set of segments. The set of segments are stored via a plurality of nodes sets, where different segments of the set of segments are stored via memory resources of different node sets of the plurality of node sets.
