The water-cooled technology tray complies with ASHRAE class A3 specifications.
Storage (non-operating):
• Temperature: 1°C to 60°C (33.8°F to 140.0°F)
• Maximum altitude: 3,050 m (10,000 ft)
• Relative humidity: 5% to 80%
• Maximum dew point: 29°C (84.2°F)
Shipment (non-operating):
• Temperature: -40°C to 60°C (-40°F to 140.0°F)
• Maximum altitude: 10,700 m (35,105 ft)
• Relative humidity: 5% to 100%
• Maximum dew point: 29°C (84.2°F)
Server off :
• Temperature: 5°C to 45°C (41°F to 113°F)
• Relative humidity: 8% to 85%
• Maximum dew point: 27°C (80.6°F)
Server on
• Temperature: 5°C to 40°C (41°F to 104°F) up to 950 m
• Humidity, non-condensing: -12°C dew point (10.4°F) and 8% to 85% relative humidity
• Maximum dew point: 24°C (75°F)
• Maximum altitude: 3,050 m (10,000 ft) & 5°C to 28°C (41°F to 82°F)
• Maximum rate of temperature change: 20°C/hr (68°F/hr) for hard disk drives
Water requirement:
• Minimum water flow rate: 6.0 liters per minute per chassis, assuming 1.0 lpm per compute tray with 6
trays per chassis (1 tray consists of 2 compute nodes)
• Inlet Water Temperature: 18 °C to 45 °C (64°F to 113°F) for all processors up to and including 145 W
TDP
• Inlet Water Temperature: 18 °C to 35 °C (64°F to 95°F) for processors at 165 W TDP (E5-2698A v3)
• Maximum pressure: 4.4 bars
Note: The water required to initially fill the system side cooling loop must be reasonably clean, bacteria-
free water (<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or
distilled water. The water must be filtered with an in-line 50 micron filter (approximately 288 mesh). The
water must be treated with anti-biological and anti-corrosion measures. Refer to Water Treatment
Specification (part number 00J0351).
Particulate contamination
Attention:
• Design to ASHRAE Class A3, temperature: 36°C to 40°C (96.8°F to 104°F), with relaxed support:
– Support cloud such as workload with no performance degradation acceptable (turbo-off)
