Sandia National Laboratories

Sandia National Laboratories supports United States national security by providing science-based solutions to address threats from terrorism, cyber attacks, uncertainties over energy security and infrastructure and other challenges. To support their extensive research and development initiatives, Sandia’s IT managers are faced with consistently updating and implementing the newest, fastest and most reliable supercomputer technologies. When the laboratory sought to deploy a new supercomputer, the Sandia’s IT Facility Infrastructure and IT professionals convened to advance their approach to high-density cooling to meet Sandia’s critical need for high availability, while improving energy efficiency and processing speed.

Case Summary
Location: Albuquerque, New Mexico, USA


  • Liebert XDR rack door cooling module applied as the Sun Cooling Door
  • Liebert XDP refrigerant pumping units

Critical Need
Support high-performance computing needs while maximizing energy efficiency and delivering maximum availability.


  • Applied a rack door, refrigerant-based passive cooling system capable of removing 90 percent of server heat load before it leaves the rack.
  • Reduced energy costs by 77 percent by replacing 140 racks operating at 13 kW per rack with 36 racks operating at 32 kW per rack.
  • Minimized the organization’s environmental footprint by incorporating innovative high-density cooling technologies.

Sandia National Laboratories has developed science-based technologies to support U.S. national security since 1949. This government-owned and contractoroperated facility supports the U.S. Department of Energy’s National Nuclear Security Administration and has major research and development responsibilities in national security, energy and environmental technologies and economic competitiveness.

Liebert XDP pumping units act as an isolating heat exchanger between the building chilled water source and the circulating refrigerant. The compressor-less Units operate above dew point, providing 100 percent sensible cooling.
