I wouldn't want to spend too much time in there without ear protection! Is it common for data centers to be this loud?
Sure -- especially in the hot aisles it can be hard to have conversations. I doubt it's much worse than a nightclub though.

Eh? Certainly back when all the disks spun. That and the server fans and the A/C make quite the racket.

#34Does yelling at your disks shorten their lifespan?
Only one way to find out... weeks later "Yeah, we had to let him go. Too burned out. Caught him screaming at the SAN."
End up like this guy: https://m.youtube.com/watch?v=ghv31AUufNk

#35In case anyone needs to know, the shouter in question is none other than Brendan Gregg (of flame graph, eBPF, and Systems Performance fame). And the guy who took the video is Bryan Cantrill of Oxide Computer, DTrace, and Joyent.
I think Brendan is still peeved that this video is his most viewed video on Youtube even after all this time.
He shouldn't be too upset, views and video quality only have a very rough correlation if at all. It shouldn't be surprising that his most accessible video is his most watched one.

HN readers may also recognize Byran Cantrill from his famous rant about Oracle, which is frequently cited here: https://youtu.be/-zRN7XLCRhc?t=1980

Can you point me to your references that indicate HDDs running Solaris are the only ones prone to loud noises disrupting their mechanical nature?

Yes, whilst he has given so many other valuable talks around systems profiling, etc.. I firmly believe that this [1] still should be hanging in every system administrators bedroom around. https://www.brendangregg.com/Perf/linux_observability_tools....
I do have it hanging in my office rather than my bedroom. I wouldn't recommend putting it in the bedroom unless one's spouse is also a sysadmin.

#39We do Vibration Testing where I work (think satellite parts, simulating launch, etc). We moved to SSDs a long time ago because some of our test gear would shutdown at certain frequencies/levels during vib tests.

I've been in my share of datacenters and most of 'em are at least a little bit quieter now. Still loud, but not to the extent that you have to shout constantly.
