OH! I get it! So you’re the author of the article?
Listen bud, I don’t care who you are or where you’ve been, but cooling systems don’t “lurch.” And if an electrical panel is buzzing, you’ve got overloaded circuitry or you’ve got a short.
The only sound you hear in a data center is the whirr of cooling fans in server equipment and the constant drone of the CRAC fans. Of course there’s the occasional buzz from a server alerting to faulty hardware or a POST beep, but the words you use to personify the experience are improper.
I have two undergraduate degrees, one in English and one in Electrical Engineering, and I have graduate work in professional writing and communications. I’ve worked in IT for 20 years. You’re preaching to someone who writes engineering documentation for executives on a daily basis.
If a junior admin launches a thousand instances on servers in rack 16, and the DCIM system see a temp spike, then yes, the cooling system can “lurch” though “mild surge” is a more descriptive phrase.
Granted, a non-dynamic center, well managed doesn’t have these variations. But some DCs are not well managed (hell, some are only slightly above anarchy).
So forgive artistic licence, but since we both have been in the trenches this really comes down not to a lack of experience or knowledge on either of our parts, just literary licence and misunderstanding.
