Abstract
Methods and apparatus for improved calculation of redundancy information in RAID storage controllers. Features and aspects hereof provide for a firmware/software element (FPE) for generating redundancy information in combination with a custom logic circuit (HPE) designed to generate redundancy information. A scheduler element operable on a processor of a storage controller along with the FPE determines which of the FPE and HPE is best suited to rapidly complete a new redundancy computation operation and activates or queues the new operation for performance by the selected component.
