AI cloud provider Fluidstack is teaming up with Nvidia, Dell, and Borealis Data Center for the deployment of exascale GPU clusters.

The clusters will be hosted in Borealis’s data centers in Iceland and the Nordics. The company’s data centers are powered by 100 percent renewable energy, using hydro and geothermal power, and utilize the cold climate for free air cooling.

Borealis operates three sites in Iceland; one in Reykjavík, one in Blönduós, and one in Fitjar in Reykjanesbær. The Fitjar facility was opened in 2018 and reportedly offers 8MW. The Blönduós campus opened in 2019 and originally offered 37MW. Borealis announced the launch of a new HPC building at the Blönduós site in 2022, increasing capacity at the site by 12MW. The data center outside Reykjavík was acquired in 2022.

The operator also acquired a facility in Kajaani, Finland, in 2024. The site, Borealis’ first international expansion, was previously owned and operated by Finnish MSP Herman IT.

The clusters will comprise Dell PowerEdge XE9680 servers with Nvidia HGX H200 GPUs, connected via Nvidia Quantum-2 InfiniBank.

“Our mission has always been to support the most exceptional AI labs, researchers, and enterprises on the planet,” said Cesar Maklary, co-founder and president of Fluidstack. “In collaboration with Borealis, Dell, and Nvidia, we can rapidly deploy high-density GPU supercomputers for both European and global customers, all while using 100 percent renewable energy.”

“We’re looking forward to working with Fluidstack, Borealis, and Nvidia to deploy advanced, sustainable AI infrastructure across Europe,” added Arun Narayanan, SVP of Compute and Networking, Dell Technologies. “Dell PowerEdge XE9680 servers combined with Nvidia’s GPUs and networking are purpose-built to efficiently support rapidly growing AI workloads, helping customers achieve unprecedented efficiency and scalability while lowering cost and energy usage.”

Fluidstack was founded in 2017 at Oxford University. With more than 100,000 GPUs under management, the company’s infrastructure is used by the likes of Mistral, Character.AI, Poolside, and Black Forest Labs.

Earlier this year, the company signed a Memorandum of Understanding with the French government to build an AI supercomputer in a facility with more than 1GW of dedicated AI compute capacity. It is expected to host close to 500,000 AI chips in its first phase.

In February 2025, Borealis secured $148 million in funding from infrastructure investment firm Infranity and Iceland’s Arion Bank, to support a planned expansion in the Nordics. The data center company was founded in 2014 and is 92.2 percent owned by Vauban Infrastructure Partners, a European infrastructure asset manager, through its Fund Core Infrastructure Fund III SCS SICAV-SIF.
