Technical rules for GPU

GPU configuration that you implement on your server requires a specific PSU configuration as well as configuration of other components..

GPU installation rules​

GPU installation rules
  1. ThinkSystem ST650 V2 does not support mixing GPUs between PCIe slots 1 and 4 or between slots 5 and 8.

    • When a GPU is installed between PCIe slots 1 and 4, only the same type of GPUs can be installed in other slots between 1 and 4.

    • When a GPU is installed between PCIe slots 5 and 8, only the same type of GPUs can be installed in other slots between 5 and 8.

  2. When NVIDIA A6000/RTX4000/A2/L4/T4 GPUs are installed between PCIe slots 1 and 4, these slots do not support any RAID adapter, HBA, or Retimer.

  3. When NVIDIA A6000/RTX4000/A2/L4/T4 GPUs are installed between PCIe slots 5 and 8, these slots do not support any RAID adapter, HBA, or Retimer.

  4. When NVIDIA A6000/A2000/RTX4000 are installed between PCIe slots 1 and 4, SAS tape drive or 430-8i SAS HBA are not supported.

  5. The installation of a full-length double-width GPU adapter should follow the rules specified below:

    • Follow the installation sequence: slot 1 >> 3 >> 7 >> 5

    • One or two FL PCIe adapter holders are required to have been installed corresponding to the PCIe slot(s) for the FL GPU adapter(s) to be installed. See PCIe adapter holder replacement for the installation and removal of a PCIe adapter holder.

    • When a FL DW GPU adapter is installed in PCIe slot 1, only the same type of GPU can be installed in slot 3; different types of FL DW GPUs can be installed in slot 7 and then slot 5.

    • When there is only one FL GPU installed between PCIe slots 1 and 4 or between slots 5 and 8, one or two FL GPU fillers are required to be installed on the air baffle on the same side of the FL GPU for proper cooling and airflow.

    • See GPU filler replacement for the installation and removal of a FL GPU filler.

  6. The installation of a ThinkSystem NVIDIA A2/L4 GPU adapter should follow the rules specified below:

    • When a ThinkSystem NVIDIA A2 or L4 GPU is installed—

      • between PCIe slots 1 and 4: the other slots between slots 1 and 4 only support low-profile PCIe adapters

      • between PCIe slots 5 and 8: the other slots between slots 5 and 8 only support low-profile PCIe adapters

      • The system does not support T4 GPU (T4 GPUs and A2/L4 GPUs cannot be installed in the system at the same time).

    • When one or more A2/L4 GPUs are installed between PCIe slots 1 and 4 or between PCIe slots 5 and 8, one or two A2/L4 GPU air ducts are required to be installed on the fan cage at the same side as the installed A2/L4 GPU for proper cooling and airflow. See A2/L4 GPU air duct replacement for the installation and removal of an A2/L4 GPU air duct.

    • A T4 filler is required to be installed on the server cover for proper cooling and airflow when one or more A2/L4/T4 GPU adapters are installed. See T4 filler replacement for the installation and removal of a T4 filler.

  7. Active GPUs can be installed in PCIe slots 1, 3, 5, and 7; ThinkSystem NVIDIA A2/L4 GPUs can be installed in PCIe slots 1 to 8.

Note

  • When A2/L4 GPU(s) are installed, up to four drive backplanes are supported.

  • When other types of GPUs are installed, only up to two backplanes or backplates are supported, and no optical drive or tape drive can be installed.

  • One PSU configuration does not support GPU greater or equal to 70W.
