This document discusses integrating energy efficiency and sustainability into high-performance computing (HPC) initiatives. It outlines HP's services for HPC data center consulting, design, implementation, and management. Direct air and indirect air cooling are currently common, but facilities are moving toward liquid cooling. Modular, scalable designs allow flexibility between air and liquid cooling. Co-locating HPC data centers with other building types improves opportunities for heat reclamation. Future HPC data center designs must prepare for multiple mechanical systems and large piping infrastructures to support high-density liquid cooling.

4. HPC Data Center Facility
Hot Buttons
– Research computing strategic to customer’s mission
– Flexibility, scalability and energy efficiency
– Data Center Facility funding typically NOT in IT/Research budgets
– Back-up Power a “Want”, rather than a “Need”
– HPC data centers typically NOT Tier III+ Facilities
– Large Compute Load requires additional MEP space
– High-Density Cooling (20-100 kW/rack)
• Liquid cooled IT now or in the near future
– Expedited Construction Schedule to accommodate new system
– Construction Budget often underestimated
– Campus central plant vs. Self-contained infrastructure analysis

5. HPC Data Center Facility
Current State Sustainability
– Airside Cooling
• Direct OA Economizer
− Water for humidification only
− Very low PUE
− Outside air quality must be good
− Scalable and modular
− Many configurations possible
− Must separate intake and exhaust
− Containment a good match
• Indirect OA Economizer
− Outside air quality not an issue
− More mechanical room space req.
− Very low PUE
− Outside air quality must be good
− Scalable and modular
− Many configurations possible
− Must separate intake and exhaust
− Containment a good match

9. HPC Data Center Facility
What is changing?
– New liquid cooled designs focused on high delta T to enable more
heat reclaim

10. HPC Data Center Facility
What is changing?
– More kW per rack and greater reliance on liquid cooling lead to piping
planning issues
• Space needed to inspect, service and modify piping
• Space for multiple systems
• Space for removal and replacement

11. HPC Data Center Facility
Special Opportunities
– Modular and Scalable Approach
– Co-location of building types that can yield big benefits from heat
reclaim
• Office
• Laboratory
• Central Plant
• Food Service

12. – HPC data center design issues to maximize
sustainability
• Flexibility to accommodate air and liquid cooling
• Prepare for multiple mechanical systems
• Large piping infrastructure likely
• Opportunities to maximize heat reclaim
