Accelerator population rules

Observe the following population rules when installing an accelerator in the node:

  • The FlexibleLOM 2U node riser cage assembly supports one accelerator option. Install the accelerator into slot 2.
  • A three-slot riser cage assembly supports a maximum of two accelerators.
    • If installing a single NVIDIA GRID K2 RAF GPU, NVIDIA Tesla K80 GPU, NVIDIA Tesla M60 GPU, NVIDIA Tesla M40 GPU, NVIDIA Tesla P40 GPU, or NVIDIA Tesla P100 GPU, install it into slot 3 and leave slot 4 empty.
    • For all other accelerator models, and to ensure proper thermal cooling, populate both slot 3 and slot 4 with accelerators.
    • The mixing of different accelerator models is not supported.

  • If installing an NVIDIA Tesla P100 GPU or NVIDIA Tesla P40 GPU, note the following guidelines and limitations:

    • The HPE Apollo r2800 Chassis does not support server nodes installed with NVIDIA Tesla P100 GPUs.

    • If NVIDIA Tesla P40 GPUs are installed in the server node, and the server node is installed in the HPE Apollo r2200 Chassis, the inlet ambient temperature must be maintained at or below 30°C (86°F).

    • If NVIDIA Tesla P40 GPUs are installed in the server node, and the server node is installed in the HPE Apollo r2600 Chassis or HPE Apollo r2800 Chassis, the inlet ambient temperature must be maintained at or below 25°C (77°F).

    • If NVIDIA Tesla P100 GPUs are installed in the server node, and the server node is installed in the HPE Apollo r2200 Chassis, the inlet ambient temperature must be maintained at or below 24°C (75.2°F).

    • If NVIDIA Tesla P100 GPUs are installed in the server node, and the server node is installed in the HPE Apollo r2600 Chassis, the inlet ambient temperature must be maintained at or below 20°C (68°F).

    • To ensure proper thermal cooling when NVIDIA Tesla P40 or NVIDIA Tesla P100 GPUs are installed in the server node, bezel blanks must be installed in specific drive bays. For more information on supported drive configurations, see the server user guide on the Hewlett Packard Enterprise website.
