description Variable Redundancy Distributed (VRD) RAID controller in a data storage environment contains embedded RAID logic permitting to choose and compute a desired redundancy coding scheme from a plurality thereof pre-programmed and embedded in a Compute Engine in the VRD RAID controller. "Write" or "Read" requests which are received from data generating entities, contain information identifying a type of the redundancy coding scheme of interest. The controller decodes the request, and automatically applies the desired computation to the incoming data without burdening the CPU with the computational activity. The variable redundancy computational ability of the subject systems provides an extremely versatile and flexible tool for RAID operations.
