Challenges - Increasing Heat DensitiesChallenges - Increasing Heat Densities
IT• Business Continuity
• Information outages• Business loss• Raised-floor yield
• Costs• Inefficient cooling• Cancelled agreements
• Warranty• Maintenance
Facility• Reliability
• Random outages• Ghosts
• Operations• Hot spots• Low airflow• Low static pressure• HVAC incapacity• Operations costs
Data Centre Equipment TrendsData Centre Equipment Trends
• Hotter equipment, packed in smaller footprints requiring more cooling capacity
• Additional cooling capacity typically comes from adding more cooling units
• Reclaim Lost Capacity before Adding More• Seal unmanaged openings wasting cold air
• Increase airflow, static pressure and capacity• Decrease cooling costs

• There is little mixing of cold air across the boundary layer of adjacent cooling unit discharge plumes
• Some mixing of returning hot air occurs

Bypass Airflow White PaperBypass Airflow White Paper
• Extensive field research of data centres• The typical, high end data centre had:
• 2.7 X required cooling capacity installed• 10% of cabinets still had hot spot problems
• Risks the Business Continuity mission– Reduced reliability, ghosts and hardware failure
• 60% of conditioned airflow bypassed the computer equipment air intakes
Bypass AirflowBypass AirflowField Data - 23 Sites - 200,000 Ft²Field Data - 23 Sites - 200,000 Ft²
Airflow Bypass ImpactsAirflow Bypass Impacts
• 50% to 80% bypass air observed in many sites has three impacts - all unwanted• Hot Spots• Cooling unit incapacity
• Incapacity: Any condition that prevents cooling unit from delivering rated capacity - dirty filters, fouled surfaces, leaks, latent cooling, etc.
• Latent cooling penalty
Latent Cooling Penalty - Latent Cooling Penalty - From Bypass AirflowFrom Bypass Airflow
• Reduction in return air temperature results in Latent Cooling which removes moisture from the air
• Moisture removed must be subsequently replaced to maintain relative humidity above the level required for computer hardware reliability
• The energy consumed to replace lost moisture (rehumidification) is the latent cooling penalty
Related Environmental & ReliabilityRelated Environmental & ReliabilityBypass Airflow IssuesBypass Airflow Issues
• Temperature Related Outages• Too Cold - condensation shorts & bridges• Cooling Unit “Set-point Spiral”
• Reducing set-point to force cooling lowers return air temperature which increases both cooling unit incapacity and latent cooling
• Humidity Related Outages• Too High - condensation & latent cooling• Too Low - electrostatic discharge
• 22°C 72°F / 45% RH Re-circulated becomes• 29°C 85°F / 29% RH ESD Danger!
