Thermal rules for server with 9004 series processors

This topic provides thermal rules for the server with 9004 series processors.

Note

  • The maximum supported DIMM quantity is 12.

  • cTDP is short for Configurable Thermal Design Power. It refers to the maximum supported power of a processor.

  • System performance may be impacted when the operating temperature is above 35 °C.

  • When a 10 x 2.5" AnyBay backplane is used, only the following two configurations support closed loop heat sink:

    • 10 x 2.5" NVMe (Gen 4)

    • 8 x 2.5" NVMe (Gen 5)

Processor groups are defined as follows:

  • Group B: 200 W ≤ cTDP ≤ 240 W

  • Group A: 240 W < cTDP ≤ 300 W

  • Group E: 320 W ≤ cTDP ≤ 400 W

Heat sink types and fan types in the tables are abbreviated as follows:

  • Air cooling heat sink: AC

  • Closed loop heat sink: CL

  • Performance fan: P

  • Standard fan: S

Standard configurations: server models with front drive bays only​

This section provides thermal information for server models with front drive bays only.

Note

  • To support rear 2 x 2.5" SAS/SATA or NVMe (U.2/U.3) drives, the following conditions need to be met:

    • Gen 4 low-profile riser installed in Riser 1

    • No Riser 2 installed

    • No 7mm drives

    • No PCIe adapter installed in slot 2 and slot 3

  • 10 x 2.5" AnyBay front backplanes support rear NVMe (U.2/U.3) drives but do not support rear SAS/SATA drives.

GPU configurations: server models with GPU adapters​

This section provides thermal information for the GPU configuration.

The server supports the following GPUs:
  • Low-profile, half-length, single-wide:

    • NVIDIA® A2

    • NVIDIA® L4

Note

All GPU configurations require performance fans.
