Yes water isn't typically used in datacenters, halon gas can be used for example. But the noise of the nozzles releasing the gas can actually damage disk drives.

There's a nozzle for that :) - http://www.fire-protection.com.au/news/hush-nozzle

From what I understand, using water/dry pipe isn't unheard of. Some prefer it over Halon - https://blog.equinix.com/blog/2014/03/26/we-must-protect-thi... .

> We think water is superior to using the firefighting chemical compound Halon, because water Is less damaging to technology and Halon can destroy circuit cards.

Did not know Halon could destroy circuit cards. Apparently it also damages the Ozone.

Yeah, some of them are literally CFCs.

yeah, the data center affected apparently had a halon gas suppression system.
