Abstract
A method for storing data. The method including receiving a request to write data. In response the request, selecting, a grid location in a grid to write the data, writing the data to memory, updating a data structure to indicate that the grid location is filled. The method further includes determining, using the data structure, whether a data grid in the grid is filled, where the grid location is in the data grid and based on a determination that the data grid is filled: calculating parity values for the grid using the data, determining a physical address in persistent storage corresponding to the grid location, writing the data to a physical location in persistent storage corresponding to the physical address, and writing the parity values to the persistent storage.
