Description
Notes:
• The fans will temporarily run at higher speeds on system boot due to processor
power calibration.
• 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.
– Min configuration: one 105W processor, four 16 GB DIMMs, two 480 GB SSD
drives, two onboard 10GB LAN ports, one 750W power supply unit.
– Typical configuration: two 125W processors, sixteen 32 GB DIMMs, eight SAS
hard disk drives, one 530-8i RAID Adapter, two onboard 10GB LAN ports, two
750W power supply units.
– GPU configuration: two 165W processors, thirty-two 64 GB DIMMs, eight SAS
hard disk drives, one 930-8i RAID adapter, two onboard 10GB LAN ports, eight
Nvidia Tesla T4 GPU adapters, two 1800W 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.
