OVHCloud celebrates 20 years of liquid cooling

European cloud provider OVHCloud is celebrating its 20th anniversary delivering proprietary liquid-cooled data centres.

OVHCloud has been developing, using and refining a liquid-cooled system to dissipate waste heat emitted by server components since 2003.

Over its lifetime the data centre company has grown to operate 34 data centres globally with over 450,000 servers.

The company is continually innovating, and has adopted a Delta T = 20K benchmark for its latest data centres, a designation of the temperature difference between water coming in and out of the data centre.

This rating has led to the group’s water usage effectiveness ratio of below 0.31/kWh, which represents the equivalent of a glass of water used to cool down a single server during 10 hours of use. By comparison, the cloud industry average water usage effectiveness ratio is 1.81/kWh.

OVHCloud’s data centres also operate at an average power usage effectiveness (PUE) of 1.28, lower than the industry average of 1.55.

Thanks to its innovations in eco-friendly cooling systems, OVHCloud has targeted using 100% low-carbon energy sources by 2025 and aims to contribute to global net zero on full scope emissions by 2030.
