Ambient temperature
management
Adjust ambient temperature when specific components are installed:
• Keep ambient temperature to 35°C or lower when one or more of the following
components are installed.
– Processors with 165 to 205 watts
– DRAM DIMMs with capacity larger than 64 GB
• Keep ambient temperature to 35°C or lower when the following components are
installed in the same unit.
– Processors with 205 to 250 watts
– 24 drives
• Keep room temperature to 30°C or lower when one or more of the following
components are installed.
– Processors with 205 or more watts
– Intel(R) Xeon(R) Platinum 8356H (190W , 8 core)
– 256 GB 3DS RDIMM
– Nvidia T4
– PMEMs
Note: To avoid triggering throttle, it is advised that the ambient temperature is
kept 27°C or lower when PMEMs are installed.
Environment
ThinkSystem SR850 V2 complies with ASHRAE Class A2 specifications. Depending on
the hardware configuration, some models comply with ASHRAE Class A3 and Class A4
specifications. System performance may be impacted when operating temperature is
outside AHSARE A2 specification.
• Air temperature:
– Operating
– ASHARE Class A2: 10°C to 35°C (50°F to 95°F); the maximum ambient
temperature decreases by 1°C for every 300 m (984 ft) increase in altitude
above 900 m (2,953 ft).
– ASHARE Class A3: 5°C to 40°C (41°F to 104°F); the maximum ambient
temperature decreases by 1°C for every 175 m (574 ft) increase in altitude
above 900 m (2,953 ft).
– ASHARE Class A4: 5°C to 45°C (41°F to 113°F); the maximum ambient
temperature decreases by 1°C for every 125 m (410 ft) increase in altitude
above 900 m (2,953 ft).
– Server off: 5°C to 45°C (41°F to 113°F)
– Shipment/storage: -40°C to 60°C (-40°F to 140°F)
• Maximum altitude: 3,050 m (10,000 ft)
• Relative Humidity (non-condensing):
– Operating
– ASHRAE Class A2: 8% to 80%; maximum dew point: 21°C (70°F)
– ASHRAE Class A3: 8% to 85%; maximum dew point: 24°C (75°F)
– ASHRAE Class A4: 8% to 90%; maximum dew point: 24°C (75°F)
– Shipment/storage: 8% to 90%
• Particulate contamination
Attention: Airborne particulates and reactive gases acting alone or in combination
with other environmental factors such as humidity or temperature might pose a risk to
the server. For information about the limits for particulates and gases, see
“Particulate contamination” on page 7.
Note: The server is designed for standard data center environment and recommended
to be placed in industrial data center.
