Abstract
The author presents a method for encoding an array of disks in such a way that the information is protected against two disk failures. The encoding requires two redundant disks and this performance is optimal. The encoding and decoding circuits require only exclusive-OR operations, giving them an advantage over other methods involving finite field operations, like Reed-Solomon codes
