ING Romania datacenter last weekend went offline after a fire drill. The storage systems were upset by the vibrations caused by the release of inert gases.

ING Romania Saturday held a fire drill in its data center, but at 13.00 began to pose problems due to the emissions of gases, reports the bank. The fault was not until 23:00 that day and customers were able to carry out any transactions or online banking. ING Romania switched to his backup updatacentrum and let them know the problems took longer to resolve than expected “because of the size and complexity of the interference.

In the drill, the ING tested the extinguishing system, which is often based on server rooms on the ejection of inert gases, typically nitrogen and argon. The gases reduce the oxygen level, which does extinguish the fire. These types of systems, the equipment does not damage nor makes for great temperature drops. However, a side effect is that the gases are emitted under such high pressure through small holes in the storage cylinders that can come at relatively much noise.

According Motherboard reached the noise level at ING Romania 130 decibels. “It was as high as our measuring instruments could record,” said an employee. The vibrations that caused the sound, influenced the hard drives: the vibrations of the actuators made sure that deviated the read and write heads of the tracks. Motherboard refers to a paper by IBM, which states that a small deviation of the head due to vibrations from the sound of all gas emissions to stop reading and writing provides.
