Note
  • 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 depending on configuration/conditions.
    • Typical configuration: four processors with TDP 205W, thirty-two 64GB RDIMMs, eight SAS hard disk drives, RAID 940-8i, Intel X710-T2L 10GBASE-T 2-port OCP, two 1100-watt power supply units.
    • GPU configuration: four processors with TDP 165W, two NVIDIA A100 GPUs, thirty-two 64GB RDIMMs, twenty-four SAS hard disk drives, RAID 940-16i, Intel X710-T2L 10GBASE-T 2-port OCP, two 1800-watt power supply units.
    • Storage rich configuration: four processors with TDP 205W, thirty-two 64GB RDIMMs, twenty-four SAS hard disk drives, RAID 940-8i, Intel X710-T2L 10GBASE-T 2-port OCP, two 2600-watt power supply units.
  • 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.
