@atYevP Do you guys do anything special regarding HDD vibrations? I am assuming your special case is built with this in mind. It is crazy how many things one has to consider at such scale. Things people normally do not care about!
- brianwski 9y agoNot Yev but I also work at Backblaze. Most of the anti-vibration tech is straight forward, like the fans aren't bolted to the chassis, they are held by rubber rivets, and we have slowly but steadily improved the "pressure" that drives are held in place to limit failures, etc. From time to time, a fan will "half fail" causing large vibrations which can massively increase drive failures in the rack that bad fan is in.
- chrisper 9y agoThanks. Another question I got for you is: What is louder? The fans or all the disks together? I had a workstation with 6 spinning disks and that was already quite loud.
- atYevP 9y agoNow it's Yev - you'd have to ask our DC techs. Every time I go to the datacenter it "feels" like the loudest part are the fans, but my ears aren't attuned to what is causing which ruckus :P
