Abstract
The disclosure provides a very flexible mechanism for a storage controller to create RAID stripes and to re-create corrupted stripes when necessary using the erasure coding scheme. Typically, this is known as a RAID 6 implementation/feature. The erasure code calculations are generated using the Galois Multiplication hardware and the system controller can pass any polynomial into the hardware on a per stripe calculation basis. The polynomial value is passed to the hardware via an input descriptor field. The descriptor controls the entire computation process.
