For a list of supported processors, see:

Lenovo ServerProven website

  • Processors are factory-installed only; no field upgrade.

    • 6242R

    • 6246R

    • 6248R

    • 6258R


The server contains 24 DIMM slots, which can be populated with 16 GB or 32 GB registered DIMMs (RDIMMs) in quantities of 8, 12, 16, or 24.
All DIMMs installed in the server must be the same type and capacity.
  • Minimum configuration: 128 GB using 8 RDIMMs

  • Maximum configuration: 768 GB using 24 RDIMMs

See Memory module installation for supported DIMM types and population rules.

For a list of supported DIMMs, see: Lenovo ServerProven website


List of supported memory module is different for 1st generation (Skylake) and 2nd generation (Cascade Lake) Intel Xeon processors. Make sure to install compatible memory modules to avoid system error.

  • Up to eight 2.5-inch hot-swap SATA drives using the onboard RAID controller.

  • Up to eight 2.5-inch hot-swap SAS drives using a supported RAID adatper or HBA.

  • Up to two M.2 drives mounted on a vertical M.2 backplane.

Expansion slots

  • Two PCIe 3.0 x16 slots and one PCIe 3.0 x4 slot in the I/O expansion cage

  • Two PCIe 3.0 x16 slots in PCIe expansion cage 1

  • Two PCIe 3.0 x16 slots in PCIe expansion cage 2

For detailed information, see Front view.

Input/Output (I/O) features

  • Front panel:

    • One VGA connector

    • One USB 2.0 connector and one USB 3.0 connector

  • Rear panel:

    • One serial port

Graphics processing unit (GPU)

The server supports the following double-width, full-height, full-length (FHFL) GPUs, which can be installed in the 3-slot PCIe expansion cage only:
  • NVIDIA P40

  • NVIDIA V100 16 GB

  • NVIDIA V100 32 GB

  • AMD Radeon Instinct MI25

For a list of supported GPU adapters, see:


With GPUs greater than 250W (such as the AMD MI-25) and CPUs greater than 165W and 165W low TCase SKUs (8180, 8168, 6154, 6146, and 6144), full performance cannot be guaranteed and CPU throttling might occur for ambient temperatures above 30°C.

The server also supports the following single-width, full-height, half-length (FHHL) GPU, which can be installed in the 4-slot PCIe expansion cage or in the 3-socket PCIe expansion cage:
  • NVIDIA T4 70W Low Profile 16 GB

If you choose to install a single-width, full-height, half-length GPU in the 3-socket PCIe expansion cage, you must install in either the top slot of the bottom slot. The middle slot does not have PCIe connectivity.

RAID adapters

  • ThinkSystem RAID 530-8i PCIe adapter

  • ThinkSystem RAID 730-8i 2GB PCIe adapter

  • ThinkSystem RAID 930-8i adapter

    The adapter supports data retention by using NAND flash memory down on the adapter, backed up by the ThinkSystem RAID 930 supercapacitor (called a supercap).

Host bus adapter

  • ThinkSystem 430-8i SAS/SATA 12 GB Dense HBA
  • ThinkSystem 430-8e adapter

System fans

Six dual-rotor fans

Power supplies

Two hot-swap power supplies for redundancy support
  • 2000-watt, 220V ac

In order for the ThinkSystem products to operate error free in both a DC or AC electrical environment, a TN-S earthing system which complies to 60364-1 IEC 2005 standard has to be present or installed.

Electrical input

  • Sine-wave input (50 Hz to 60 Hz) required

  • Input voltage high range:

    • Minimum: 200 V ac

    • Maximum: 240 V ac

240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland ONLY. Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.

Acoustical noise emissions (base configuration)

  • Sound power, idling: 6.7 bels

  • Sound power, operating (typical workload): 7.3 bels

  • Sound power, operating (maximum workload): 8.3 bels

  • The options supported in this server vary in function, power consumption, and required cooling. Any increase in cooling required by these options will increase the fan speed and generated sound level. The actual sound pressure levels measured 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 of other equipment; the room ambient temperature and barometric pressure; and the location of employees in relation to the equipment.

  • The declared acoustic noise level are based on specified configurations and they may change depending on configuration/condition changes.

  • The declared acoustic noise levels may increase greatly, if high-power components are installed such as high-power NICs, high-power processors and GPUs.

Heat output

Approximate heat output:

  • Minimum configuration: 2543.86 BTU, 746W (in BTU per hour and watts)

  • Maximum configuration: 6963.22 BTU, 2042W (in BTU per hour and watts)

    • Maximum configuration of two processors, 24 memory modules, two M.2 adapters, three PCIe network adapters, eight HDDs, four GPUs, two 2000W power supplies


The server is supported in the following environment:
  • Air temperature:

    • Operating:

      • ASHRAE class A2: 10–35°C (50–95°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 300 m (984 ft) of altitude increase.

    • Server off: 5–45°C (41–113°F)

    • Shipping or storage: -40–60°C (-40–140°F)

      • ASHRAE class A2: 8%–80%; maximum dew point: 21°C (70°F)

    • Shipping or storage: 8%–90%

  • Particulate contamination

    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.
  • Your server complies with ASHRAE class A2 specifications. The server performance might be impacted when the operating temperature is outside the ASHRAE A2 specifications.

  • The server is designed for standard data center environment and recommended to be placed in industrial data center.
