Note
The RDIMM supporting has the following conditions:
  • When the capacity of each RDIMM is less than or equal to 64 GB, standard fans are used.

  • When the capacity of each RDIMM is equal to or greater than 128 GB, performance fans are used.

  • When the capacity of each RDIMM is 256 GB, the ambient temperature must be limited to 30°C or lower.

Server models with GPUs

This section provides thermal information for server models with GPUs.

  • Single-wide GPU: T1000, T400, A2

  • Double-wide GPU: RTX A2000, RTXA4500, RTXA6000, A30, A16, A100, A40, H100

Note
  1. For T400 and T1000, only a maximum of six single-wide GPU adapters are supported.

  2. For the chassis with 16 x 2.5-inch front drives, a maximum of two A40 or H100 GPU adapters are supported in PCIe slot 2 and slot 5 when the ambient temperature is 30°C.

  3. A40 is not supported by the chassis with 24 x 2.5-inch front drives.
