Abstract

Storage of data according to mapped reliability groups (MRGs) of mapped redundant arrays of independent nodes (mapped clusters) is disclosed. Real reliability groups (RRGs) of a real cluster can provide compartmentalization that can reduce a probability of a data loss event occurring in a cluster storage system. MRGs for a mapped cluster employing the RRGs of the real cluster can provide additional compartmentalization that can further reduce a probability of a data loss event occurring. A data protection set can be stored according to a first group of MRGs and a redundant representation of the data protection set can be stored according to a second group of MRGs, wherein a network distance between the first and second group of MRGs is greater than a network distance between constituent MRGs of either the first or second group of MRGs.
