Benefit from Last-Mile Connectivity with Minimal Latency.

The Stockton campus delivers prime last-mile connectivity with an 18-mile 288-strand redundant fiber ring to our carrier-neutral data center housing multiple network providers. Physically independent connections to the carrier’s long-haul and metro networks deliver direct connectivity to cloud services and your enterprise.


Our colocation data center is proven and practical. Here are the specs on power, cooling, security, and connectivity ranging from rack to vault.

  • 69kV bulk substation feeds the Nautilus on-premise substation via a dedicated 12kV 10MW feed
  • 480V utility power feeds from on-site substation via diverse paths to the facility
  • N+1 block redundancy with “4 to make 3” design
  • On-site fuel storage to support 26 hours run time per generator at full load plus one full engine/fuel redundancy. Two fuel providers under contract, a third in reserve, with 24x7x365 priority fuel delivery
  • Diverse primary and reserve power distribution to each data hall
  • Power density up to 55kW for 30” racks, 35kW for 24” racks


  • The proprietary cooling technology is a primary/secondary heat exchanger coupled system. The primary side handles intake, filtering, and discharge of water from the San Joaquin River. The secondary side operates under vacuum to pull the water through the data hall, maintaining ASHRAE A1 allowable temperature ratings year-round
  • The system cools more than 800 watts per square foot without consuming any water and uses 30% less power than traditional centers
  • Each data hall has four parallel leak proof cooling distribution units – N+1 concurrently maintainable configuration, each fed by redundant open-loop systems
  • System is under vacuum –  meaning there is no threat of leaks or water touching an IT load designed to maintain ASHRAE A1 Standards

Environmental Performance

Nautilus is proud to have demonstrated the water-cooling technology can achieve the highest standards of environmental performance required by the US government and the State of California. Our ​team worked collaboratively with federal, state, and local professionals responsible for environmental stewardship to secure all regulatory approvals.

For the Stockton 1 Data Center this included water quality, air quality, public trust and natural resources, endangered species, state species, wetlands, and environment.
