Acoustical noise emissions
The server has the following acoustic noise emissions declaration:
Sound power level (LWAd)
Typical: 6.1 Bel
Storage rich: 6.8 Bel
GPU: 7.4 Bel
Typical: 7.0 Bel
Storage rich: 7.5 Bel
GPU: 8.2 Bel
Sound pressure level (LpAm):
Typical: 47 dBA
Storage rich: 53 dBA
GPU: 60 dBA
Typical: 55 dBA
Storage: 61 dBA
GPU: 67 dBA
These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296.
The declared acoustic sound levels are based on the specified configurations, which may change slightly depending on configuration/conditions.
Typical configuration: four 165W processors, twenty-four 64 GB DIMMs, twenty-four SAS hard disk drives, 930-8i, Intel X710 10 GB 2 port, four 1100-watt power supply units
Storage rich configuration: four 205W processors, forty-eight 64 GB DIMMs, forty-eight SAS hard disk drives, 940-16i, Intel X710 10 GB 2 port, four 1100-watt power supply units
GPU configuration: four 205W processors, forty-eight 64 GB DIMMs, forty-eight SAS hard disk drives, 940-16i, Intel X710 10 GB 2 port, eight Nvidia Tesla T4, four 1800-watt power supply units
The declared acoustic noise levels may increase greatly, if high-power components are installed such as high-power NICs, high-power processors and GPUs.
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.
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
Keep room temperature to 30°C or lower when one or more of the following components are installed.
Processors with 205 or more watts
ThinkSystem SR860 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.
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):
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)
