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.
