Environmental specifications

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

Note

  • SD665 V3 tray contains two nodes; one left node and one right node (when viewed from front of enclosure). Both are compute nodes.

  • Up to six SD665 V3 trays can be installed in the DW612S 6U enclosure.

Acoustical noise emissions
SD665 V3 Tray:
  • Sound power level (LWAd):
    • Idle: 6.5 Bel
    • Operation: 7.7 Bel
Note

  • These levels were measured in controlled acoustical environments according to procedures specified by ISO 7779, and are reported in accordance with ISO 9296.

  • The declared acoustic noise levels are based on specified configurations with 6 air-cooling PSUs in the DW612S 6U enclosure, and may change depending on configuration/condition changes.

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)

  • 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)

Note
The solution is designed for standard data center environment and recommended to be placed in industrial data center.
Water requirements
6900W (200-208 Vac) DWC power supply

  • Water temperature:

    • ASHRAE class W+: up to 50°C (122°F)

  • Maximum pressure: 4.4 bars

  • Minimum water flow rate:1.0 liters per minute per power supply

    • For inlet water temperatures up to 45°C (113°F), 1.0 liters per minute per power supply

    • For inlet water temperatures between 45°C - 50°C (113°F - 122°F), 1.5 liters per minute per power supply

7200W (220-240 Vac and 240 Vdc) DWC power supply

  • Water temperature:

    • ASHRAE class W+: up to 50°C (122°F)

  • Maximum pressure: 4.4 bars

  • Minimum water flow rate:1.5 liters per minute per power supply

    • For inlet water temperatures up to 45°C (113°F), 1.5 liters per minute per power supply

    • For inlet water temperatures between 45°C - 50°C (113°F - 122°F), 2.0 liters per minute per power supply

SD665 V3 tray installed in the DW612S enclosure is supported in the following water temperature

  • Water temperature:

    • ASHRAE class W45: up to 45°C (113°F)

      • CPU up to 400W TDP

      • DIMMs up to 64 GB capacity

    • ASHRAE class W32: up to 32°C (89.6°F)

      • 128GB DIMMs

  • Maximum pressure: 3.5 bars

  • Typical water flow rate for ASHRAE class W45: 12 liters per minute (lpm) per enclosure, assuming 2.0 liters per minute per compute tray with 6 trays per enclosure (1 tray consists of 2 compute nodes)

  • Minimum water flow rate for ASHRAE class W32: 9 liters per minute (lpm) per enclosure, assuming 1.5 liters per minute per compute tray with 6 trays per enclosure (1 tray consists of 2 compute nodes)

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.
