Between the 40s and 80s, my grandfather worked for a bunch of companies in the tree and steel industry. One of them produced wood boards (some kind of plywood or particle wood) that you would place underneath the computer in the computer room to absorb vibrations in the building. I was always fascinated by stories like that.

As it turns out that most drives are sensitive to sounds below 100Hz or neat 1kHz. We adapted our siren pattern and eliminated the problem. We found this video after the fact..

There was a very popular online photo service that was having cooling issues in their datacenter. They brought in some large floor fans to help cool it down while they waited for repairs. Within 8 hours they were in a full panic as they have lost 40% of the disks in that whitespace. Well one guy started mapping out the lost drive physical location and realized that servers that were within a few feet of the fans had almost complete disk loss. Vibration is Hard Disk killer.
@GothAlice2 жыл бұрын
Jarrod, spot on. Had one question come up about a loss of performance after adding a bunch of new disks to the arrays, I asked: what's the harmonic frequency of the spin rates between old drives versus the new? I love when interviewers ask real questions, and begin texting other engineers. And the look, "that… is unexpected" when the responses come back.

Just wait till you accidentally find a resonant frequency for those nand chips, I bet that same frequency will also cause problems with the rest of your computer.

@@andreasjoannai6441 The resonant frequency of NAND chips typically falls into the higher end and outside the audible range of human hearing, way beyond subwoofer-related frequencies. Sub sound frequencies are incapable of resonating them. A HDD is a totally different story though.

@@andreasjoannai6441 Of course you can. But, again, the resonant frequency (specifically of NAND chips) falls into the higher end of the sound frequencies and outside the audible range of human hearing, way beyond subwoofer-related frequencies. The reading needles in a HDD are susceptible by lower up to middle frequencies. On the other hand, NAND chips would need a high frequency so strong that probably no current twitter-speakers can produce. Subwoofers are incapable of producing so high frequencies since their range is typically from around 20 Hz to 200 Hz. The upper limit of human hearing is often considered to be around 20,000 Hz (20 kHz), while beyond the range of human hearing, there are ultrasonic frequencies used in various applications such as medical imaging, industrial processes, and animal communication. These frequencies typically start from around 20,000 Hz and extend into the megahertz (MHz) range and these are the ones that can actually influence NAND chips, if strong enough.
