My 71 TiB ZFS NAS After 10 Years and Zero Drive Failures

4U 71 TiB ZFS NAS built with twenty-four 4 TB drives is over 10 years old and still going strong. Although now on its second motherboard and power supply, the system has yet to experience a single drive failure (knock on wood).

It wasn't enough for me to just turn off the server, but leave the motherboard, and thus the BMC powered, because that's just a constant 7 watts (about two Raspberry Pis at idle) being wasted (24/7). This setup required a ton of UTP cables so eventually I got bored with that and I bought some cheap Infiniband cards and that worked fine, I could reach around 700 MB/s between systems. As I decided to move away from Ubuntu and back to Debian, I faced a problem: the Infiniband cards didn't work anymore and I could not figure out how to fix it.
