Water requirement
Attention
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. Environment quality must be maintain over the lifetime of the system to receive warranty and support on affecting components. For more information please see Lenovo Neptune Direct Water-Cooling Standards.

Environment
Attention

Environment quality must be maintain over the lifetime of the system to receive warranty and support on affecting components. For water quality requirement, see Lenovo Neptune Direct Water-Cooling Standards.

The SD650 V2 tray, the SD650-N V2 tray and DW612 Enclosure are supported in the following environment:
  • Air temperature requirements:

    • Operating: ASHRAE class A2: 10°C - 35°C (50°F - 95°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 300 m (984 ft) of altitude increase.

    • Powered off: 5°C - 45°C (41°F - 113°F)

    • Shipping/storage: -40°C - 60°C (-40°F - 140°F)

    To use the 240 GB M.2 drive, the following conditions must be met:

    • If inlet water temperature is 45°C, then the ambient air temperature cannot exceed 27°C.

    • If inlet water temperature is 30°C, then the ambient air temperature cannot exceed 35°C.

  • Relative humidity (non-condensing):
    • Operating: ASHRAE Class A2: 8% - 80%, maximum dew point : 21°C (70°F)
    • Shipment/storage: 8% - 90%

  • Maximum altitude: 3048 m (10 000 ft)

  • Particulate contamination:

    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 solution. For information about the limits for particulates and gases, see Particulate contamination.

Note
The solution is designed for standard data center environment and recommended to be placed in industrial data center.
