Thermal rules

This topic provides thermal rules for the server.

Note
  • TDP is short for Thermal Design Power.

  • Direct Attach Cables (DAC) are supported when the bandwidth of PCIe adapter or OCP module is equal to or more than 100 GB.

Sever models with front drive bays only

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

Sever models with PCIe/OCP adapters (≥ 100GB) installed

This section provides thermal information for server models with PCIe/OCP adapters (≥ 100GB) installed.

The maximum supported DIMM quantity is 12.
