Abstract
In accordance with embodiments of the present disclosure, a method may be implemented to respond to receiving data A to be stored in a storage system that includes a plurality of N spans, each including a plurality of M drives. The method may include performing data storing operations. The data storing operations may include storing the data A in N portions across the plurality of spans, generating a Za parity based on an XOR operation applied to the N portions of the data A, storing the Za parity in N−1 portions across a subset of the plurality of spans, determining a Zap parity based on an XOR operation applied to the N−1 portions of the Za parity, and storing the Zap parity.
