The noise can cause problems for a hard drive? Apparently, yes. In fact, in recent years, had a host of problems hard disks when testing anti fire when the gas was released Inergen. And surprisingly enough, after some testing, this is not the gas that was causing problems, but ... the alarm. Indeed, the alarms used in data centers are very powerful (up to 120 decibels) and the change in air pressure by the sound wave has a visible impact on hard drives.
In tests, we see a drastic drop in disk performance when the alarm sounds for more than 45 seconds, and in some cases hard drives that fail or clerical errors. According to the hosts, there are some solutions to this problem. The first is to use SSDs instead of hard drives, but this radical solution is rarely feasible.
The others are hard to place in soundproof boxes, place the sirens so as not to direct them to the hard drives, multiply the alarms to prevent sound waves too high and reduce the discharge time of the gas.
