One more thing to watch out for at data centers - fire drills

Releasing inert gas from fire suppression units that were over pressurized resulted in an extremely loud noise – causing cabinets full of hard drives to vibrate – which got transmitted to the read – write heads of the drives.

Amazing sort of outage + data loss, and this time the physical security plant chief gets to write up the RCA.

A quick comment: for the N2 systems we built in our datacenters we added mufflers to reduce the noise which raised the price for the system by only 5%. Totally worth it. Yet many datacenters do not add them.
