Meet up

A Tutorial on Reed-Solomon Coding for Fault-Tolerance in RAID-like Systems

Wednesday, 27th July in London

This meetup was organised by Papers We Love in July 2016

Overview

A Tutorial on Reed-Solomon Coding for Fault-Tolerance in RAID-like Systems by James S. Plank

The paper [1] is for systems programmers, is quite accessible (modulo an error corrected in a follow-up 7 years later [2]) and explains a strategy to survive any number of disk failures by maintaining checksums using Galois Fields (which it also explains)

You may find it useful to also look at 'The mathematics of RAID-6' [3] explaining what the linux kernels RAID6 implementation does.
