Note

  • The declared acoustic sound levels are based on the following configurations, which might be different from the actual configurations:

    • Typical: 8 x standard fan, 2 x 205W CPU, 2 x standard heat sink, 16 x 64 GB RDIMM, 10 x 2.5 NVMe drive, 1 x ThinkSystem Broadcom 57416 10GBASE-T 2-port OCP, 2 x 800W PSU.

    • Storage rich: 8 x performance fan, 2 x 330W CPU, 2 x performance heat sink, 16 x 64 GB RDIMM, 12x 2.5 NVMe drive, 1 x ThinkSystem Broadcom 57416 10GBASE-T 2-port OCP, 2 x 1300W PSU.

  • Idle: The steady-state condition in which the server is powered-on but not operating any intended function.

  • Operating 1: The maximum acoustic output of 50% CPU TDP or active storage drives.

  • Operating 2: The maximum acoustical output of 100% CPU TDP or GPU TDP.

  • The declared sound levels may change depending on configuration/conditions, for example, with high-power NICs, high-power processors and GPUs, such as ThinkSystem Mellanox ConnectX-6 HDR/200GbE QSFP56 1-port/2-port PCIe Adapter, ThinkSystem Broadcom 57454 10GBASE-T 4-port OCP Ethernet Adapter.

  • 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.
