Power isn’t so bad really. These were all 2tb disks, so ended up with about 40tb total after shenanigans.
Cabling was atrocious. I’d originally been using several pulled 4 disk SAS backplanes from servers thrown out of my work, just screwed down to some pine boards in a stack.
Zip ties and sata/sas cables were the rule.
Overall the drives had 4 small power supplies initially, 300watt iirc. Cheap.
Somewhere I have an old photo from the wiring during the “rescue” but I have to look around.
Disk failure was actually not an issue for ages before. A specific thunderstorm with 2 nearby tornadoes is what caught me this time. Before that, the occasional single disk every 6 months or so.
I still have running arrays using 15 year old disks, many with more than 10 years of that powered on. If you find good models, they can last ages.
48 disks seems a nightmare in power consumption, failure rate, and overall cabling management…
What was the total capacity?
