Worth sharing a pointer to a really neat set of papers that describe
open source friendly RAID6 and erasure encoding algorithms that were
presented last year and this at FAST:

If I remember correctly, James Plank's papers also have implemented and
benchmarked the various encodings,
I have seen the papers; I'm not sure it really makes that much
difference. One of the things that bugs me about these papers is that
he compares to *his* implementation of my optimizations, but not to my
code. In real life implementations, on commodity hardware, we're
limited by memory and disk performance, not by CPU utilization.
