Abstract
A method for calculating parity values including calculating a first set of parity values using datum stored in RAID Grid locations in a first PCB, where datum associated with the RAID Grid locations in the first PCB is obtained in a first order that is based on a Hilbert curve. The method further includes calculating a second set of parity values using datum stored in RAID Grid locations in a second PCB, where datum associated with the RAID Grid locations in the second PCB is obtained in a second order that is based on the Hilbert curve. The method further includes storing at least a portion of the first set of parity values and a second set of parity values in a cache, memory, or persistent storage, where each of the first parity values and second parity values is associated with a separate RAID Grid location in the RAID Grid.
