AI-powered optimisation at OVHcloud While eliminating water consumption addresses one sustainability challenge, the energy efficiency of cooling infrastructure remains paramount.
OVHcloud has introduced what it calls‘ Smart Datacenters’, combining redesigned hardware with AI to reduce cooling electricity consumption by up to 50 % and water usage by up to 30 %.
The European cloud provider’ s fifthgeneration server rack features a serial cooling configuration within clusters, while maintaining parallel server organisation for maintenance access.
Hardware components including CPUs and GPUs are cooled through direct-to-chip waterblocks designed by OVHcloud, with heat dissipated through a closed-loop water circuit extending across the entire data centre.
“ We are delighted to unveil a new generation of evaporative cooling solutions, including Smart Racks,” said Miroslaw Klaba, R & D Director at OVHcloud.“ With our one integrated cooling loop design, we are paving the way for Smart Datacenters that leverage our most advanced technologies as well as artificial intelligence to tackle what was once an impossible equation.”
The cooling module, now approximately 50 % more compact than previous generations, sits outside the rack and can cool multiple rows whilst monitoring more than 30 sensors. These track pressure, flow speed and water temperature, enabling real-time adjustments to server workloads. The Smart Dry Cooler, located externally, occupies half the space and uses half the fans of earlier equipment, contributing to the 50 % reduction in cooling power consumption.
