Operating mode 26672
Note

  • These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296.

  • Idle mode is the steady state in which the server is powered on but not operating any intended function. Operating mode 1 is 50% CPU TDP. Operating mode 2 is 100% CPU TDP.

  • The declared acoustic sound levels are based on the following configurations, which may change depending on configuration or conditions.

    • Typical: 4 x 270W CPUs, 32 x 64 GB RDIMMs, 24 x 2.5" SAS HDDs, 1 x RAID 545-8i, 1 x Intel E610-T4 10GBASE-T 4-port OCP, 4 x 2000W PSUs

    • Max.: 4 x 350W CPUs, 64 x 64 GB RDIMMs, 48 x 2.5" SAS HDDs, 3 x RAID 940-16i, 2 x Intel E610-T4 10GBASE-T 4-port OCP, 4 x 3200W PSUs

  • 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​

Manage the ambient temperature for your server depending on the specific hardware components installed.

Note
The tables below show the temperature limits for servers without a liquid-cooling module (Processor Neptune® Core Module). When the liquid-cooling module is installed, the CPU supports temperatures up to 45°C regardless of the fan type or number of drives. However, other components like the GPU and NIC adapters still need to follow the same temperature limits as air-cooled systems, which are listed below.

Environment​

Environment

ThinkSystem SR860 V4 complies with ASHRAE Class A2 specifications under most hardware configurations, and depending on specific hardware configuration, it may also comply with ASHRAE Class A3, Class A4, or Class H1 specifications. Refer to Ambient temperature management for information about temperature requirement for specific hardware. The server's performance may be impacted if operated outside the specified ASHRAE temperature classes it complies with.

    Attention
    Airborne particulates and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the server. For information about the limits for particulates and gases, see Particulate contamination.

Water requirements​

Water requirements
ThinkSystem SR860 V4 is supported in the following environment:

  • Maximum pressure: 3 bars

  • Water inlet temperature and flow rates:
    • For servers with Processor Neptune® Core Module, the water inlet temperature and water flow rate can be as follows:
      Water inlet temperatureWater flow rate
      50°C (122°F)1.5 liters per minute (lpm) per server
      45°C (113°F)1 liter per minute (lpm) per server
      40°C (104°F) or lower0.5 liters per minute (lpm) per server
Attention
The water required to initially fill the system side cooling loop must be reasonably clean, bacteria-free water (<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water. The water must be filtered with an in-line 50 micron filter (approximately 288 mesh). The water must be treated with anti-biological and anti-corrosion measures. Environment quality must be maintained over the lifetime of the system to receive warranty and support on affecting components. For more information, see Lenovo Neptune Direct Water-Cooling Standards.
  • Particulate contamination
    Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the device that is described in this document.
