      It was distributed as an in-joke at a few Microsoft professional events, it wasn’t for the general public.

      Right. A lot of people loved that product. A lot of other people didn't understand why it existed. This was for both. :)

      (General comment) The mid-2000s were such an inflection point in the course of sovereign technologies. Industries testing consumer-hosted hardware solutions and distributed identity federation. I regret we couldn’t have had more of that succeed, but I understand the outcome.

      Convenience and cost trumped everything, because no one understood (or believed there would be) consequences to handing over their data and habits to "free" services. Drug pusher model got them hooked, and now here we all are as a society...

      home server was the future we could have without being locked in all sort of clouds where they use us as a product. imagine it with UWP technology today, etc.. an utopian concept nowadays, sadly..

      Let's not forget that the product, which I loved, was affected by data corruption bugs. Which convinced me to build a zfs home server still running.

      fixed now thanks to the proper solution they implemented, in part, inspired by it. that is now server/serverfarm wide working, and still awesome. it was a product of inspiration.

      The Erasure Encoding that was at the heart of Home Server is used by the entire industry now. If you have data in the cloud, chances are very high it's protected by that bit of research that came to market in WHS first. RAID was on life support long ago.

      RAID is just a special case of Erasure Coding; some EC profiles in use are actually equivalent to RAID. The bigger win IMO is the intelligent sharding and recovery of data chunks across large clusters (or pools of disks). EC by itself is really just a fancier RAID level.

      Really the math behind all of this is ancient; we've just figured out better ways to apply it than the old "one disk, one filesystem" model that RAID piggybacked on.

          LRC is a very special case. Having locality for recovery operations is what makes modern coding so critical to cloud ops. Reed-Solomon hit the wall years ago because it didn't solve locality, thus, speed.

          Do you have a citation for this approach? I'm aware of multiple solutions for RS's issues with read amplification in failure scenarios, but other than that RS is still the baseline and good on its own (and often used as the foundation for more complex schemes).
