FWIW I did a "making of" video soon after, in 2009: https://www.youtube.com/watch?v=lMPozJFC8g0 . Only bit I missed discussing there was that I did try to download freeware frequency generators wondering if there was some "rust note" of HDD harmonics, but those I downloaded didn't work and out of frustration I decided to start yelling instead.

Thanks for sharing!

I wouldn't want to spend too much time in there without ear protection! Is it common for data centers to be this loud?

It varies. Once I've been at a customer's data center with raised floors some ten years ago. It felt like an hurricane when you removed one of the tiles. Loud and cold (ear protection and wind breaker mandatory). Hard to communicate there, harder still to think. Not a nice place to be. Keep it in mind when choosing your career.

I got a "3M Peltor X5A" a couple years back as a "thinking cap": put on to think in thought-hostile environments. Works like a charm. Probably best 30 bucks I ever spent.

For comms use a wind-proof mic on a headset boom and earphones under the X5A.

I have trained myself so that every time I see "Oracle", I mentally translate it as "Larry Ellison needs a bigger yacht".

I keep picturing Larry pushing a lawn mower.

There's an interesting little paper 'Acoustic Denial of Service Attacks on HDDs' where they use a function generator to find resonant frequencies which cause issues with spinning disks

Janet Jackson's song Rhythm Nation caused certain 5400 rpm HDD's in laptops to crash:

In 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 hope to one day have the terrible misfortune of being acquired by Oracle.

Brilliant. Thanks.
