Accelerator installation information

  • The PCIe3 x16 expansion slots 1, 3, 5, and 7 support both single-width and double-width accelerators.

  • The maximum number of accelerators supported in this server depends on the drive configuration and whether the accelerator is single- or double-width.

  • This server does not support the installation of different accelerator models in the same system.

  • This server supports NVIDIA NVLink technology for specific accelerators. This technology allows two matching accelerators to communicate directly through a high-speed interconnection—NVLink bridge. This interconnection effectively combines the available memory of both accelerators for increased workload performance. For more information, see the NVIDIA website.

  • Some accelerator options shipped with an extender bracket attached or included in the option box. See the accelerator documentation for information on when this extender bracket might be required for installation.

For a list of supported accelerator models, see the product QuickSpecs on the server website at https://www.hpe.com/servers/ml350-gen10.

GPU auxiliary power cabling

Depending on the maximum power requirement of the GPU, an external auxiliary power connection might be required. See the GPU documentation for the specific auxiliary power connections required for that model.

The GPU auxiliary power cable kit consists of two cables of different lengths for:

  • GPUs installed in the PCIe x16 slots 1 and 3, use the 879289-001 power cable (1000 mm, 39.37 in).

  • GPUs installed in the PCIe slots 5 and 7, use the 876503-001 power cable (180 mm, 7.09 in).

For more information on how these cables are routed, see GPU auxiliary power cabling.

Thermal and power requirements for accelerator options

  • The fan cage option is required to meet the system thermal requirement when an accelerator is installed. For fan cage information, see Fan cage option.

  • The system operating temperature requirement will vary depending on the accelerator model, the drive configuration, and the thermal configuration setting enabled in BIOS. For more information, see the product QuickSpecs on the Hewlett Packard Enterprise website.

    To select a thermal configuration setting, from the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Fan and Thermal Options > Thermal Configuration.

  • For high-power accelerator options, Hewlett Packard Enterprise recommends using the HPE 1600 W Flex Slot Platinum Hot-plug Low Halogen Power Supply. Use the HPE Power Advisor tool to estimate the power consumption requirement based on specific system configuration. For more information on this tool, see the Hewlett Packard Enterprise website.

IMPORTANT: Workloads for high performance double-width accelerators with passive cooling can cause the fans to operate at high speeds to maintain optimum system cooling. This high-speed fan operation leads to a sound pressure level of between 75 dB(A) to 80 dB(A). Hewlett Packard Enterprise does not recommend operating the server under this passive cooling condition in or near a site where there is a reasonable expectation for a quiet environment.
