Hi all,

Erasure coding - is it a safe for use in production on an all-flash array? I'm specifically talking about VMware's vSAN here, however the question is fairly broad.

The alternative is one I'm most familiar and comfortable with; RAID1(/10) mirrored to another node(s) to provide simple/reliable fault tolerance. However, there are plenty of people talking up the new RAID5/RAID6 erasure coding features as it substantially reduces overheads. Apparently there is far less risk of failure due to the much lower URE rates in flash storage.

I'm curious what you guys think? Is it risk adverse? @scottalanmiller has posted up some passionate threads in the past about why R5/R6 is the devil (which I totally agree with) so where do you stand with erasure coding?

Thanks
