Ask HN: What are the best-designed things you've ever used?
ZFS. Complete research companies unknowingly depend on the utmost reliability and flexibility ZFS has to offer. Started right with the first version included in FreeBSD in production use and never failed once while being the central storage connected to multiple HPC clusters with millions upon millions of rather small but also some vary large files. While offering five nines of uptime we even had to ability to send efficient binary forever incremental differential snapshots to remote DR locations. Meanwhile we saw many large crashed sites at companies which had downtimes of weeks using lustre. ZFS even got hated by management because it&#x27;s not giving them fancy relationships with the normies using HP&#x2F;Dell. So the last ten years are probably the best ZFS got here because some instructed architect is looking for commercial replacement but nothing better seems available.
