This directory contains source code and coefficients for SD codes, as described in the paper "Sector-Disk (SD) Erasure Codes for Mixed Failure Modes in RAID Systems", Technical Report UT-CS-13-708, University of Tennessee, May, 2013. This is a follow-on to the Usenix 2013 FAST paper, "SD Codes: Erasure Codes Designed for How Storage Systems Really Fail"

This code was developed using the GF-Complete library for Galois Field arithmetic. GF-Complete is no longer available (please see, so to use this code, you will have to substitute another library for Galois Field arithmetic.
