> I bet we'll get one in Rust eventually. Maybe from Oxide computer company? Crucible is our storage service: https://github.com/oxidecomputer/crucible RFD 60, linked in the README, contains a bit of info about Ceph, which we did evaluate: https://rfd.shared.oxide.computer/rfd/0060

Yes, it could be NTFS behind the scenes, but this is still an apples to oranges comparison because the storage service Oxide created is Crucible[0], not ZFS. Crucible is more of an apples to apples comparison with Ceph. [0] https://github.com/oxidecomputer/crucible

Yes! Crucible[0] is on our list of upcoming episodes. We can touch on it tonight, but it's really deserving of its own deep dive! [0] https://github.com/oxidecomputer/crucible

Same is true of Oxide, it'll be up to actual experience to see how well it works. Oxide seems to have written their own distributed block storage system (https://github.com/oxidecomputer/crucible), have their own firmware, kernel and hypervisor forks, etc -- when any of that breaks, good luck!

I fully expect there will be data-loss bugs and poor performance during recovery in their in-house distributed block storage solution. That's just in the nature of the problem domain, and this is all new code: https://github.com/oxidecomputer/crucible

They use Crucible on top of ZFS. https://github.com/oxidecomputer/crucible I don't think they have anything for S3-like service but there are other options for that, e.g. https://garagehq.deuxfleurs.fr or MinIO. I am not sure whether they have their own SSDs or use of the shelf SSDs just with their firmware or something.

Just to add some additional detail: the control plane (Omicron[0] -- named before the COVID variant!), the user-level portion of the hypervisor (Propolis[1]) and the storage subsystem (Crucible[2]) are all open source. And while our focus has been building them for our own product, we know that they are at least usable outside of Oxide![3][4] [0] https://github.com/oxidecomputer/omicron [1] https://github.com/oxidecomputer/propolis [2] https://github.com/oxidecomputer/crucible [3] https://artemis.sh/2022/03/14/propolis-oxide-at-home-pt1.htm...
