Environmental specifications

Summary of the environmental specifications of server. Depending on the model, some features might not be available, or some specifications might not apply.

Ambient temperature management​

Ambient temperature management

Adjust ambient temperature when specific components are installed.

Keep the ambient temperature to 30°C or lower when ThinkSystem NVIDIA BlueField-3 B3220 VPI QSFP112 2P 200G PCIe Gen5 x16 Adapter is installed in PCIe riser 1 (PCIe slot 9).

Environment​

Environment
ThinkSystem SR780a V3 complies with ASHRAE Class A2 specifications. System performance may be impacted when operating temperature is outside ASHRAE A2 specification.
  • Air temperature:
    • Operating
      • ASHRAE 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).
    • Server off: 5°C to 45°C (41°F to 113°F)
    • Shipment/storage: -20°C to 60°C (-4°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)
    • 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.
Note
The server is designed for standard data center environment and recommended to be placed in industrial data center.

Water requirements​

Water requirements

  • Water temperature:

    • ASHRAE class W45: up to 45°C (113°F) inlet temperature to the rack

  • Maximum pressure: 4.4 bars

  • Minimum water flow rate: 10.0 liters per minute per Chassis

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.
  • Particulate contamination
    Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the device that is described in this document.
