Generalized Concatenated Codes for Block and Device Failure Protection

Peter Trifonov, Yuangang Wang

Abstract

A code construction based on generalized concatenated codes is proposed for protection against device and block failures in storage systems. Low-complexity encoding and repair algorithms for the proposed codes are presented. This construction improves upon recently proposed STAIR codes in terms of performance and achievable code parameters.
