EVENODD code[1]
Description
A binary array code that can correct any two disk failures (i.e., two erasures). See [2] for more details.
Decoding
Efficient decoding algorithm against two erasures [1].
Parents
- Generalized EVENODD code — Generalized EVENODD codes reduce to EVENODD codes for \(r=2\) [2].
- MDS array code — EVENODD codes are examples of MDS array codes [3].
