Abstract
A method for storing data. The method includes receiving data to write to persistent storage, calculating parity values for a grid using the data, where each of the parity values is associated with one selected from of the Row Q Parity Group, the Row P Parity Group, the Column Q Parity Group, the Column P Parity Group, and the Intersection Parity Group. The method further includes writing the data to a data grid in the persistent storage, where the data grid is part of the grid, and writing the parity values for the grid to a portion of the grid, where the portion of the grid comprises physical locations associated with a Row Q Parity Group, a Row P Parity Group, a Column Q Parity Group, a Column P Parity Group, and an Intersection Parity Group, wherein the portion of the grid is distinct from the data grid.
