  • Process for generating and reconstructing variable number of parity for byte streams independent of host block size
    Publication number: 20060136778
    Abstract: A method, system and program for generating parity in a data storage system are provided. The invention comprises organizing an incoming data block into a specified number of data stripes and cascading the data stripes into a parity creation mechanism. The parity creation mechanism creates a specified number of parity stripes based on the data stripes, wherein the number of parity stripes is independent of the size of the data block. The parity creation mechanism can operate offline to reconstruct lost data stripes and parity stripes without using critical system resources, wherein the number of devices required for stripe reconstruction is less than the combined number of data stripes and parity stripes.
