OVH OVH Paris Datacenter - Water Coolant Leak

eva2000 · Jul 15, 2017

OVH servers are water cooled but apparently there was a water coolant leak in their Paris datacenter What did OVH learn from 24-hour outage? Water and servers do not mix

An external water-cooling leak crashed a Dell EMC VNX array at an OVH data centre in Paris and put more than 50,000 websites out of action for 24 hours.

OVH is the world's third largest internet hosting company with 260,000 servers in 20 data centres in 17 countries hosting some 18 million web applications.

The failure took place around 7pm in OVH's P19 data centre on June 29. This was OVH's first data centre opened in 2003. It has since been surpassed in size by a Gravelines data centre, the largest in Europe, which has a 400,000-server capacity.

The incident account says: "At 6:48pm, Thursday, June 29, in Room 3 of the P19 datacenter, due to a crack on a soft plastic pipe in our water-cooling system, a coolant leak causes fluid to enter the system.

"One of the two proprietary storage bays (racks) were not cooled by this method but were in close proximity. This had the direct consequence of the detection of an electrical fault leading to the complete shutdown of the bay."

OVH admits installing them in the same room as the water-cooled servers was a mistake. "We made a mistake in judgment, because we should have given these storage facilities a maximum level of protection, as is the case at all of our sites."

Yikes!
Last time I was building my PC I was thinking about doing water cooling. Seemed like it would be too much of a hassle.

I settled with just a Corsair H100i CPU liquid cooler.
