Known problem, but not well documented
I've had a customer affected by this in the past, if I recall it's down to the frequencies emitted by one specific design of nozzle, and there are advisories out there for the fire suppression systems advising against its use in data centres.
The outage we saw affected 15k rpm drives, across several different SAN equipment manufacturers. 10k and 7k drives escaped largely unscathed.
However the damage was severe enough to totally offline around 50% of those 15k rpm drives, to the point that they wouldnt even come back after a power cycle.
Biting the hand that feeds IT
