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

  • The 6U enclosure supports up to six trays.

  • Each tray contains two nodes; one left node and one right node (when viewed from front of enclosure).

  • SD650 V3 tray contains two compute nodes.

Acoustical noise emissions
SD650 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 (one enclosure with 6 PSUs), and may change depending on configuration/condition changes.

  • Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employee's location in relation to the equipment. Further, compliance with such government regulations depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.

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.
