CHICAGO – October 30, 2025 – Data center real estate investment trust CoreSite has announced a significant expansion of its relationship with managed services provider STN, securing the company's new GPU cloud venture as a customer at its CH2 facility in Chicago.
STN has selected CoreSite's Chicago data center to host "GPU One," its graphical processing unit cloud platform dedicated to artificial intelligence workloads. The deployment, scheduled to launch in April 2025, will comprise a substantial cluster of more than 1,500 liquid-cooled Nvidia B200 GPUs housed in SuperMicro servers across 24 racks.
“CoreSite has been a trusted partner throughout STN’s growth journey,” said Sabur Mian, STN CEO. “When it came time to scale GPU One, our private cloud service for AI builders, we turned to CoreSite for their leadership in liquid-cooled, high-density deployments. CoreSite is a leader in liquid cooling in the colocation data center space, and its ability to deliver a customer’s primary liquid cooling solution at CH2 for us is what sealed the deal.”
The partnership represents a continuation of a relationship that began in 2019 when STN started with a single rack at CoreSite’s SV7 facility in Santa Clara, California. The company has since expanded its footprint to include CoreSite's LA1 data center in Los Angeles and now the CH2 location in Chicago.
CoreSite is supporting the high-density deployment with liquid cooling infrastructure capable of handling more than 100kW per rack. The company noted that more than 90 percent of customers in the multi-tenant computer room where STN is located at CH2 utilize liquid cooling solutions.
The GPU One cluster is already committed to supporting workloads for robotics startup Skild Brain, among other AI-focused clients. STN stated that its managed services allow customers to focus on core AI competencies like model training, fine-tuning, and inference, while STN and CoreSite ensure infrastructure uptime.
CoreSite, which operates 30 facilities across 11 US markets, broke ground on the 18MW, 169,000-square-foot CH2 data center in 2019. The facility, located at 1432 S. Clinton Street, launched the following year. American Tower acquired CoreSite for $10.1 billion in November 2021, and Stonepeak subsequently acquired a 29 percent stake in the CoreSite business for $2.5 billion in 2022.
